Pecan foliage is attacked by three species of aphids [Monellia caryella (Fitch), Melanocallis caryaefoliae (Davis), and Monelliopsis pecanis Bissell], resulting in damage that can reduce tree nut yield. In this study, we assayed the ovipositional response of the green lacewing Chrysoperla rufilabris (Burmeister) to M. caryella and M. caryaefoliae at high and low aphid densities and the developm...
Abstract Background The predatory mite, Blattisocius mali Oudemans (Mesostigmata: Blattisociidae), feeds on various species of storage mites such as Tyrophagous putresentiae (Schrank). In this study, life table parameters and consumption rates B. were determined when fed the eggs larvae T. putrescentiae prey under laboratory conditions. Results Based age-stage two-sex analysis, total pre-ovipos...
Gustatory stimuli have at least 2 kinds of function: They can support immediate, reflexive responses (such as substrate choice and feeding) and they can drive internal reinforcement. We provide behavioral analyses of these functions with respect to sweet taste in larval Drosophila. The idea is to use the dose-effect characteristics as behavioral "fingerprints" to dissociate reflexive and reinfo...
Thediamondbackmoth,Plutella xylostella (L.) (Lepidoptera: Plutellidae), amajor pest of cruciferous crops throughout the world, has demonstrated an ability to develop resistance to many different classes of insecticides, including proteins from Bacillus thuringiensis that are expressed in plants (Bt plants). The ovipositional preferences and larval survival of strains (resistant strain, RR; hete...
Ivermectin treatment of all cattle on a badly infected farm failed to interrupt the transmission of P. bovicola, even though ovipositional blood spots were drastically reduced in numbers for an entire summer season following treatment. Regular weekly to fortnightly dipping of all cattle in 50 ppm deltamethrin immediately reduced vector fly numbers to less than 1 fly per cow face. Sustained dipp...
