چکیده
J. Econ.Entomol.79: 1139-1142 (1986) ABSTRACT A Heliothis cone trap captured significantly higher numbers of male European corn borers, Ostrinia nubilalis (Hubner), than a sticky wing trap. Behavioral observations revealed that the difference in number of males captured was related to the proportion of moths approaching the traps that was subsequently captured. Cone traps baited with a 97:3 blend of (2)and (E)-ll-tetradecenyl acetate captured 87%of those males that entered the trap compared with 6% for the wing traps.

Comparison of mating disruption and mass trapping with Pyralidae and Sesiidae moths
Mating disruption and mass trapping for control of lepidopteran pests use synthetic sex pheromone to prevent males from finding and mating with females. Here, we identify the behavioral mechanism underlying mating disruption and mass trapping of American plum borer, Euzophera semifuneralis (Walker) (Lepidoptera: Pyralidae), peachtree borer, Synanthedon exitiosa Say, and lesser peachtree borer, ...
متن کاملGenetic variation in the strongly canalized sex pheromone communication system of the European corn borer, Ostrinia nubilalis Hübner (Lepidoptera; Pyralidae).
The major difference in pheromone production between the so-called E and Z strains of the European corn borer Ostrinia nubilalis is controlled by two alleles at a single autosomal locus. E-strain females produce an (E)-11-tetradecenyl acetate pheromone with 1-3% of the Z isomer, whereas Z-strain females produce the opposite blend. In laboratory-reared insects we found that F1 females produced, ...
متن کاملNo linkage between genes controlling female pheromone production and male pheromone response in the European corn borer, Ostrinia nubilalis Hübner (Lepidoptera; Pyralidae).
The E and Z pheromonal strains of the European corn borer, Ostrinia nubilalis, are characterized by female production of and male preference for opposite blends of (E)-11-and (Z)-11-tetradecenyl acetate. It is known that the pheromone production is controlled by an autosomal gene and that the males' behavior is determined by a sex-linked gene. A third gene, autosomally inherited, has been shown...
متن کاملImpact of trap design, windbreaks, and weather on captures of European corn borer (Lepidoptera: Crambidae) in pheromone-baited traps.
Pheromone-baited traps are often used in ecological studies of the European corn borer, Ostrinia nubilalis (Hübner) (Lepidoptera: Crambidae). However, differences in trap captures may be confounded by trap design, trap location relative to a windbreak, and changes in local weather. The objectives of this experiment were, first, to examine differences in 0. nubilalis adult (moth) captures among ...
