Role of Bacteria in Mediating the Oviposition Responses of Aedes albopictus (Diptera: Culicidae)
Only volatiles collected from larval rearing water elicited significant electroantennogram responses in females, and water containing Psychrobacter immobilis, Sphingobacterium multivorum, and an undetermined Bacillus species elicited significantly higher oviposition than control water without bacteria.
Synergism of pheromone and host‐plant volatile blends in the attraction of Grapholita molesta males
The observed enhanced male attraction to mixtures of pheromone and plant volatiles will facilitate the development of lures for G. molesta adult flight monitoring.
IMMUNOLOCALIZATION OF TOMATO YELLOW LEAF CURL SARDINIA VIRUS IN NATURAL HOST PLANTS AND ITS VECTOR BEMISIA TABACI
The antiserum labelled, for the first time, the primary glands of the salivary gland system of TYLCSV-viruliferous B. tabaci, suggesting that the circulative pathway of TY LCSV can be completed as intact virions.

Five volatile synthetic chemicals tested as potential oviposition attractants of Aedes albopictus do not appear to be effective lures for baiting ovitraps for surveillance or control of this mosquito.
Male and Female Antennal Responses in Heliothis virescens and H. subflexa to Conspecific and Heterospecific Sex Pheromone Compounds
The hypothesis that autodetection of sex pheromones occurs in females of both H. virescens and H. subflexa is supported, although whether females behaviorally respond to any, or to combinations, of these compounds remains to be elucidated.
Diurnal variation of walnut tree volatiles and electrophysiological responses in Cydia pomonella (Lepidoptera: Tortricidae).
Walnut volatile emissions differ widely from apple ones, but both share many compounds that are EAD-active in C. pomonella, however, among Ead-active compounds there are three walnut-specific ones, which should be further tested in behavioural assays.
Sexual Approach in the Praying Mantid Mantis Religiosa (L.)
It is concluded that males of M. religiosa can assess the activity state of the females and respond to this information by modulating their speed of approach, probably reducing the risk of being detected and possibly cannibalized.
Transmission of Spanish pepper- and potato-PVY isolates by aphid (Homoptera: Aphididae) vectors: epidemiological implications
Transmission tests between different species of aphids using PVY∘-infected pepper and tobacco as source plants indicated that M. persicae was the most efficient vector, followed by Aphis gossypii Glover and Acyrthosiphon pisum Harris.

It is concluded that Z11-16:Ald is a potent antagonist of the behavioral response of O. nubilalis and stimulates a different odor receptor neuron than the pheromone components of O.
Day-Night and Phenological Variation of Apple Tree Volatiles and Electroantennogram Responses in Cydia pomonella (Lepidoptera: Tortricidae)
Volatile compounds from apple trees were collected in the field from attached apple branches enclosed in plastic bags in the morning and at dusk and during three growth periods (after petal fall, immature fruit, and close-to-full ripening [CFR]).
