Written in English
The European corn borer, a destructive pest of many agricultural commodities as well as ornamental and native plants, was not found after 265 pheromone-traps were placed and monitored in Western Washington.

This is a research project. Western bean cutworm (WBC; Striacosta albicosta) has invaded the Northeast Region in recent years. This pest species new to the Northeast attacks corn (Zea mays; including field and sweet corn) and both dry beans and snap beans (Phaseolus vulgaris), feeding on developing corn kernels or beans.

A trapping system utilizing attractive pheromones is described for the suppression and survey of western pine beetle,Dendroctonus brevicomis LeConte (Coleoptera: Scolytidae), populations over large forested areas and for extended periods of time. Two types of compactable sticky traps are described. A large vane trap was developed for population by: For example when corn plots were treated with a regular dosage of kg, 2,4-D/ha, aphid numbers on the corn averaged 1, whereas on the untreated they averaged only (Oka and Pimentel ). Corn borer infestation averaged 28% in the 2,4-D treated corn population compared with only 16% in the untreated corn population.
Enter Non-Technical Summary in this block. California growers account for 46 percent of fruit and nut crop production output in the United States and 62 percent of the national value of fruit and nut crops, with annual farm receipts for these crops exceeding $ billion. Managing arthropods (principally insects and mites) in horticultural crops presents a number of challenges for both. If there’s a sex pheromone trap in the center of the room, it will draw the male from wherever it may be. We may see that male in the trap and think the source of the infestation is in the center of the room, where the trap is. But, since that male could have come from anywhere in the room, the infestation source could be anywhere.

Generally, leaf and tassel feeding can be ignored. If beetles are present and feeding on corn silks, an insecticide should be applied only if on average the silks are being cut off to less than 1/2 inch before 50% pollination has taken place.
This rarely happens on a field.

European Corn Borer, Ostr-in-la nub-Halis Leaves are damaged by larvae feeding in the whorl; tunnelling is seen in the stalk; stalks break, ears fall due to feeding in the ear shank. Earlier generation larvae destroy food-conducting vessels with consequent weakening of the plant, re- duction of ear size and weight, of number of grains and grain.
Trichogramma Ostriniae and European Corn Borer in Sweet Corn: Ina survey of organic growers found that the most important research priority was “insect pests” and that beneficial insect habitat was very high on their list of interests.

Pope. Control in corn that has already pollinated, will likely be less than 50%. 1 larva/ear at dent stage corn is approximately equal to a 4 bushel/acre loss (Nebraska and Iowa data).
Ear damage opens the door for molds, a concern in food grade corn. Larvae in the ear will NOT be controlled.
Pheromone-mediated mating disruption (MD) represents an important tool to manage insect pests in agriculture and forestry. MD relies on the release of synthetic sex pheromones from dispensers in crops, interfering with mate finding and reproduction of a pest through both competitive and non-competitive mechanisms.
MD programs primarily rely upon “passive” dispensers, used at high Cited by: 1. There are typically 2 to 3 generations of corn borer that affect corn fields. This update will focus more on the first generation.
Generation 1. The first generation of European corn borer usually emerges around late May or early June. They are dependent on heat units for growth and spread.
