Corn farmers in the Philippines have incurred great yield losses in the past decades because of ACB infestation Bt corn in the Philippines was designed to be resistant to the Asiatic corn borer (ACB), Ostrinia furnacalis (Guenee), one of the nation's most destructive corn pests
. The present corn borer control recommendation advocates a schedule of insecticide applications as a preventive measure The Philippines approved GM corn for commercial use in December 2002, primarily to help farmers control the Asian corn borer, a highly destructive insect pest that lowers yields and can destroy up to 80 percent of a crop. Farmers were using pesticides to fight the insect, which created a human and environmental health risk and increased. These are the corn seedling maggots (Atherigona oryzae Malloch.), the root grubs (Leucopholis irrorata (Chev.)), the corn borer (Ostrinia furnacalis Guenee) and the corn earworm (Helicoverpa armigera Hubn.). The most damaging is the corn borer, the other pests may cause sporadic damage
Bt corn in the Philippines was engineered to be specifically resistant to the Asiatic Corn Borer (ACB), Ostrinia furnacalis (Guenee), the most devastating corn pests in the industry. It was introduced as a practical and ecologically sustainable solution for poor corn farmers, a major bullet to combat poverty and improve livelihood . To control corn borer, apply trichocards 20-25 days after palnting with 100 cards per hectare, space at 10m x m. However, if infestation exceeds the tolerable limit, spray with insecticides at recommended rate. Another method in controlling pest during tasseling stage is through detasseling The Bureau of Agricultural Research (BAR) sees native corn's continued cultivation in the Philippines despite the growing popularity of higher-yielding hybrid varieties. BAR, an agency under the Department of Agriculture, is cooperating with the Institute of Plant Breeding of the University of the Philippines Los Baños (IPB-UPLB) and DA regional field offices (RFOs) in implementing [
North Luzon farmers have found a hybrid corn variety originally developed to fight the highly devastating Asiatic corn borer to be similarly resistant to the just emerging fall armyworm that is now infesting Philippines' corn farms. A relatively new pest in the Philippines that has already invaded Southeast Asia from its As such, the plants have a built-in mechanism of protection against targeted pests, including Asian corn borer. The farm level economic benefit of planting Bt corn in the Philippines in the period 2003 to 2016 is estimated to have reached US$724 million, ISAAA reports Caterpillar of the Asian corn borer, Ostrinia furnacalis, inside a maize cob. The caterpillars are pinkish-brown Observable damage symptoms of ACB (a) and non-ACB (b) infestations in corn plants surveyed in Isabela province, The Philippines, during the 2010 wet growing season. - Asian corn borer (ACB) and non-ACB pests in GM corn (Zea mays L.) in the Philippines. Figure 2 The pest is called Asian corn borer (scientific name: Ostrinia furnacalis). Over the past decade or so, corn borer infestation has occurred yearly with pest pressure constant to increasing over time, said the paper entitled, Impact Assessment of Bt Corn Adoption in the Philippines
The Asian corn borer is most commonly found throughout Asia and Southeast Asia. More specifically, it is located in China, the Philippines, Indonesia, Taiwan, Malaysia, Thailand, Sri Lanka, India, Bangladesh, Japan, Korea, Vietnam, Lao, Myanmar, and Cambodia. There are also a limited number in the Solomon Islands, Africa, and parts of Australia Ang isang uod ng Asian Corn Borer o ACB kada halaman ay napag-alamang makakabawas ng hanggang 17% sa ani ayon sa Centre for Agriculture and Bioscience International (CABI). Ang bilang ng mga butas sa tangkay ay maaring gawing indikasyon sa pagbaba ng ani. Ang ACB ang pinaka-mapaminsalang uod ng mais dahil ito ay kumakain sa ubod ng puno ng mais
Techniques for control of the Asian corn borer in the Philippines. Author Affiliation : Department of Entomology, College of Agriculture, University of the Philippines at Los Banos, College, Laguna, Philippines. Conference paper : Proceedings of the Asian Regional Maize Workshop 1988 No.3 pp.105-116 ref.19 Asiatic corn borer. This diet includes wheat germ and kidney bean as major ingredients. Since 1981, the corn group at IPB (Insti tute of Plant Breeding) of the University of the Philippines at Los Banos has conducted a research project on breeding for the corn borer resistance. An artificial diet, on whic Syngenta developed a corn line resistant to the Asiatic Corn Borer (ACB) larvae, a periodic pest of corn in the Philippines. This corn line referred to in this document as Bt 11, was developed to provide a method to control yield losses from insect feeding damage caused by the larval stages of ACB, without the use of conventional pesticides.
Survey of Asian corn borer (ACB) in Chapter2 showed that Bt corn efficiently reduce borer pest problem and damage to plants by 44%. No secondary pest outbreak was found in Bt cornfields yet, occurrence of ACB though at an insignificant level, could imply potential development of Bt toxin resistance Dark-headed and Abundant in lowland Rice, corn, sugarcane, Luzon, Visayas, Gold-fringed and upland rice fields. grasses Mindanao 3. 4 Striped stem borer Chilo suppressalis (Walker) Pink stem borer Common stem borers in the Philippines.

In the Philippines, Bt corn adoption has grown by leaps and bounds
Cauayan, Isabela, Philippines - Plantings of Genetically Modified (GM) corn increased from 10,769 ha of Bt corn in 2003 to 455,391 ha (94% stacked trait events, 4% Bt corn and 2% glyphosate tolerant corn) in 2010. Cagayan Valley is the major corn growing regions with 251,925 ha planted to GM corn in 2010 Bt corn or YieldGuard 818 Corn Borer is a genetically modified organism (GMO), where a specific Bt gene is inserted to produce a protein that protects the corn plant from feeding by Asiatic corn borers (ACB). This makes the corn plant naturally resistant to attack by ACB The tropical corn borer, Ostrinia furnacalis (Guenee), is one of the most damaging pests in areas where corn has been grown for several years in Thailand. This insect caused yield losses of more than 50% in many districts and up to 96% in Malaysia, and the Philippines (Areekul, 1971a).. To seek answers to the issues on GM corn adoption in the Philippines, the thesis focused to find answers on the general question: How can genetically modified (GM) corn and its attributed changes in agricultural practices affect the agro-ecosystem's biodiversity and the economic status and social life of the farmers? Survey of Asian corn borer (ACB) in Chapter2 showed that Bt corn.
Bayer said the variety has a dual mode of action for protection against fall armyworm, corn borer, corn earworm, and other above-ground pests notorious for wreaking havoc on corn crops leading to. In the Philippines and parts of Southeast Asia, Asian corn borer (Ostrinia furnacalis) is a serious pest of maize, and injury from this insect often is associated with the occurrence of bacterial stalk and ear rot (caused by Erwinia chrysanthemi pv.zeae).The effect of transgenic insect protection on the incidence of bacterial stalk and ear rot was studied in the Philippines with seven field. The Asian corn borer is a serious pest of maize in Vietnam, Indonesia, Thailand, and the Philippines. 25 One of the major reasons for the low productivity of maize in India and Pakistan is damage by insects, notably spotted stem borers. 24 Stem borers damage the vascular tissue of the plant and provide a portal of entry for stalk and ear rots.
The first day of the activity was dedicated to presentations regarding the following topics: Corn Insect Pests in the Philippines, Insect Resistance Management of Bt corn and its Implementation in the Philippines, Role of Refuge in Delaying Insect Resistance to Bt crops, Addressing Developed Resistance of Target Insect Pest of Bt crops. Caasi-Lit, M. T., & Fernandez, E. C. (2006). Survey of alternate host plants of Asian corn borer (Ostrinia furnacalis (Guenee)) in major corn production areas of the Philippines Asian corn borer, a major pest that was found to steal 30-40% corn yield from Filipino farmers. It carries a transplanted gene from Bacillus thuringensis (Bt), a common soil bacterium, that produces a protein which when eaten by the corn borer makes the insect sick and eventually die. After 10 years of commercial planting, the geneticall The potential yield from GM corn was said to be double or triple the national average of three metric tons per hectare. Among the genetically-modified variants locally available is Bacillus thuringiensis (Bt) corn, which has a built-in resistance against the Asiatic corn borer
Over the last two decades, corn growers in the Philippines (as in other countries) have widely adopted genetically engineered corn containing both Bt and herbicide-tolerance traits. A major corn pest there is the Asian corn borer (a relative of the European corn borer) Internationally, my focus has been on the Philippines, the first Asian country to adopt Bt corn technology for Asian corn borer, a pest closely related to European corn borer. In January 2006, Filipino scientists hosted by the PI attended the annual meeting (in Toronto) of entomologists working on this multi-state project College, Laguna, corn while also serving as oviposition sites for corn borer Philippines: University of the Philippines Los Baños. but not supporting larval growth.

Farmers planting the genetically-engineered Bt corn are asking seed producers to make planting materials more affordable. A study by the Biotechnology Coalition of the Philippines (BCP) show that. Before the introduction of Bt crop, corn was a problematic crop to grow during the dry months. This is because of the Asian Corn Borer that is endemic to the Philippines and preys on crops like corn to devastating effect. Corn farms afflicted by Asiatic Corn Borer (ACB) and Ostrinia furnacalis (Guenee) could hardly come up with efficient yield Bt-corn contains gene from soil bacterium Bacillus thuringiensis, enabling the crop to produce its own insecticide to beat off corn borer. Despite strong opposition, the second Bt-corn testing of Pioneer Hi-Bred Philippines is ongoing at Polomolok town in Southern Cotabato. The first test concluded March last year in General Santos City

For more information and inquiries, please contact Department of Agriculture MIMAROPA - Regional Agricultural and Fisheries Information Section (RAFIS). What is Corn Borer Transgenic corn producing Cry1Ac toxins from Bacillus thuringiensis (Bt) provides effective control of Asian corn borer, Ostrinia furnacalis (Guenée), and thus reduces insecticide applications. However, whether Bt corn exerts undesirable effects on non-target arthropods (NTAs) is still controversial. We conducted a 2-yr study in Shangzhuang Agricultural Experiment Station to assess the. The first GE variety of corn, which was commercialized in 1996, expressed a Bt toxin that targeted European corn borer, southwestern corn borer, and several other pests (see Table 1-2). GE corn with resistance to glyphosate was released in 1997, followed by a variety with resistance to glufosinate in the next year (Dill, 2005) Maize (/ m eɪ z / MAYZ; Zea mays subsp. mays, from Spanish: maíz after Taino: mahiz), also known as corn (North American and Australian English), is a cereal grain first domesticated by indigenous peoples in southern Mexico about 10,000 years ago. The leafy stalk of the plant produces pollen inflorescences and separate ovuliferous inflorescences called ears that yield kernels or seeds, which. The refuge system is an important requirement to keep pests such as corn borer from becoming resistant to Bt corn. Romero said the proliferation of illegal seeds threatens the corn industry in the Philippines. The two kinds of illegal seeds discreetly sold in the market are named ukay-ukay seeds and sige-sige seeds, Romero bared.

Yadao 4. 1 Crop Protection Cluster, University of the Philippines Los Baños, College, Lagun It's called biotech corn because its genes have been altered to develop resistance to corn borers and to tolerate chemical herbicides that are sprayed to kill weeds in corn fields. The Philippines, which grows approximately 2.5 million hectares of corn, is the only country in Asia to approve and grow a major biotech feed and food crop 1980). Therefore, other methods to control Asian corn borer would be desirable. In some parts of the Philippines, detasseling corn plants is practised as a corn borer control method (Yadao 1983). Removal of tassels is commonly used in hybrid seed production to prevent pollination of female parents, and a ratio of one male row to three. Eurobellia annulata is a predatory earwig which can be used as biological control for the Asian corn borer (Ostrinia furnacalis Guenee). It released into the field at the rate of 1 per square meter to control the Asian corn borer population. The technology is a way to mass-rear the earwigs using factitious hosts (dog food and corn cob)
Bt helps ward off the voracious corn borer and should help bring down pesticide use, says Monsanto. The decision had been hotly contested by anti-GM protestors and even some provincial governments. GM corn also enabled the Philippines to export corn silage as the disease-resistant corn plants remain free from holes from pest infestation. CropLife Philippines is an association of companies that help improve the productivity of Filipino farmers and contribute to Philippine food security in a sustainable way Waxy or glutinous corn is one of the major crops grown in the Philippines with over a million Filipino farmers, depending on it as their main source of income and employment. With the increasing population of Filipinos and the rise in the market demand for cornicks, local production of waxy corn grains has always been barely able to support the demand of the processing industry A major pest of corn, the European corn borer (Ostrinia nubilalis) will also feed on over 300 different garden plants including peppers, snap beans, potatoes, tomatoes, apples and gladiolus.Damage to corn is caused by the young larvae which chew leaves and tassels. Later they tunnel all parts of the stalks and ears, resulting in reduced plant vigor, broken stalks, poor ear development and.

Asian Corn Borer, Ostrinia furnacalisr Ostrinia furnacalis, Asian corn borer moth is an important insect of maize, millet, mung bean, and many grasses. It is also known as Oriental Corn Borer or Asian Maize Borer The Department of Agriculture of the Philippines recognized the importance of Bt maize when it gave approval for commercial planting of Monsanto's Bt maize in December 2002. Aside from other data, the basis of this approval was the demonstrated efficacy of this material against the Asiatic corn borer (ACB) under Philippine conditions The so-called Bt corn is one of the products of research by companies that spend a lot of money for research and development. The Bt corn is now a favorite variety of corn farmers in Isabela, Ilocos and elsewhere because this so-called genetically engineered corn can protect itself from the destructive Asian corn borer. This pest bores holes in the stem of the corn plants, often resulting in. The corn is really clean and the profits are good, the ISAAA quoted Paraluman as saying. Carlos Andico, another farmer from the same village, said Bt corn was the answer to their biggest problem, the Asiatic corn borer pest, which if unchecked, could cut corn harvest by 30 to 40 percent depending on the location and on the weather

GM yellow corn was planted to more than 700,000 hectares; more than half the area for yellow corn. Two types of GM corn are planted, Roundup Ready (herbicide tolerant) and stacked Bt/Roundup Ready (Asian corn borer resistant, herbicide tolerant). Seeds of Bt corn were not available in 2013 because farmers prefer the stacked Bt/Roundup Ready. - Rice (Philippine Rice Research Institute - PhilRice) - Papaya, sweet potato, eggplant, tomato, coconut (University of the Philippines at Los Banos - UPLB) - Corn (private industry) • GM corn approved for commercial cultivation: - MON 810 corn (corn borer resistant), (Monsanto (2002) - NK 603 corn (herbicide tolerant), Monsanto (2005 The Philippines is an archipelago of some 7,107 islands located between 4° and 21° N latitude and 116° and 127° E longitude.
