Impact 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 ...
متن کاملHigh-efficiency Pheromone Trap for the European Corn Borer (Lepidoptera: Pyralidae)
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 ble...
متن کاملQuantitative assessment of biotic mortality factors of the European corn borer (Lepidoptera: Crambidae) in field corn.
Five treatments were used to exclude naturally occurring predators and parasitoids, based on body size and flight ability, to assess their effect on Ostrinia nubilalis (Hübner) populations on corn plaits. Two initial O. nubilalis egg densities (one egg mass and three egg masses per plant) were assigned to each treatment. Egg predation was higher in uncaged treatments than in caged treatments. F...
متن کاملLate-instar European corn borer (Lepidoptera: Crambidae) tunneling and survival in transgenic corn hybrids.
Field studies were conducted in 1996 and 1997 to determine injury by and survival of late-instar European corn borer, Ostrinia nubilalis (Hübner), on genetically altered Bacillus thuringiensis Berliner corn, Zea mays L. Cry1Ab events 176, Bt11, MON810, and MON802; Cry1Ac event DBT418; and Cry9C event CBH351 were evaluated. Plants of each corn hybrid were manually infested with two third-, fourt...
متن کاملOviposition by European Corn Borer (Lepidoptera: Crambidae) in Response to Various Transgenic Corn Events
Oviposition preference by European corn borers, Ostrinia nubilalis (Hübner), for or against transgenic corn would influence amounts of refuge required for resistance management. The objective of this research was to determine if various Bacillus thuringiensis (Bt) corn transgenic events influence O. nubilalis oviposition. All commercially available events (currently 5) were evaluated, plus 1 ex...
