The Role of Attractants and Feeding Stimulants in The Selection of Cucurbita Flowers by Diabroticite Beetles, (Coleoptera: Chrysomelidae)
… indole, produced a substantial response in an electroantennogram bioassay. Field testing of indole using sticky traps showed it to be a potent attractant of the western corn rootworm, Diabrotica virgifera virgifera Le Conte and the striped cucumber beetle, Acalymma vittatum (Fabr.). The …

Chemical Manipulation of Honey Bee Behavior
… melon flowers and knapweed in field experiments. Electroantennogram recordings were conducted to verify an olfactory response of the bees to the tested compounds. Pheromonal compounds were readily detected by bee antennae; whereas, the HCAs did not elicit significant responses in the bee antennae. …

Effects of an insecticide on German cockroach behavior
… antennal grooming, and tarsal grooming. Electroantennogram studies showed that the vapors of the propoxur formulation were detected by the antennae. Adults of the susceptible VPI strain responded more strongly to the insecticide vapors, relative to the controls, than did adults of the …

Mating Success in Low-Density Gypsy Moth Populations
… disruption treatments. Finally, a portable Electroantennogram (EAG) device was evaluated for its ability to detect disparlure sprayed for mating disruption in gypsy moth populations. The study found no relationship between the dose of artificial airborne pheromone and response of gypsy moth …

Biology and host finding of predaceous hister beetles (Coleoptera: Histeridae) associated with Ips spp. (Coleoptera: Scolytidae) in loblolly pine (Pinus taeda L.)
The most common predaceous Histeridae (Coleoptera) found associated with Ips engraver beetles (Coleoptera: Scolytidae) in Louisiana were Platysoma attenuata LeConte, Pla. cylindrica (Paykull), Pla. parallelum (Say), and Plegaderus transversus (Say). Seasonal abundance of histerids in flight traps …

Factors affecting the response of thrips to an olfactory cue
… Spain has occurred. Additional experiments using electroantennogram (EAG) technique showed that Spanish WFT can detect MI at least at the peripheral olfactory reception level, and suggest that the non-response is due to failure in the olfactory signal pathway of the central nervous system. While …

Plant-insect interactions between female dogwood borer and apple
… sensilla present. Coupled gas chromatography and electroantennogram detection (GC-EAD) analyses of headspace collections from damaged and undamaged tissues from apple and dogwood trees were conducted to examine and compare the antennal responsiveness of female dogwood borer to host plant …

Sex pheromone studies on the grass grub (Costelytra Zealandica (White)) and the common army worm
… phenols but none of these was active. An electroantennogram was developed to measure the antennal response to phenol and a number of closely related phenolic materials. In all the tests, phenol gave the largest response. A comparison at the antennal level between phenol and a crude female …

Utilizzo di tecniche elettrofisiologiche e comportamentali indirizzate al controllo eco-compatibile di popolazioni di insetti di interesse ambientale, sanitario e agronomico
The Mediterranean fruit fly, Ceratitis capitata Wied., is a worldwide pest for horticulture because of its high biological potential, the difficulty of control and the broad polyphagy, mainly addressed, in Southern Europe, to pomaceous (apples and pears) and citrus (oranges) cultures. Information …
