Host plant water status is thought to influence dispersal of the xylophagous leafhopper Homalodisca vitripennis Germar, especially where plants are grown under high evaporative demand. Preference by adult H. vitripennis for plants grown under different water deficit and nitrogen form fertilization regimens was studied under laboratory conditions. Leafhopper abundance and ovipositional preferenc...

High mixing ratios of ground-level O3 threaten trophic interactions. In the present study, we conducted laboratory assays, where insect larvae and adults were not directly exposed to O3, to test the feeding behavior and attraction of the coleopteran leaf beetle Agelastica coerulea to early and late leaves of Japanese white birch (Betula platyphylla var. japonica) treated with ambient or elevate...

abstract: the potato tuberworm, phthorimaea operculella (zeller), is an important insect pest of potato (solanum tuberosum l.) in the storage and field in most parts of the world especially in tropical and subtropical regions due to its close relationship with the host, high reproductive potential and high economic losses. information on host preference, life table parameters and digestive en...

Aphids are one of the most serious pests of crops worldwide, causing major yield and economic losses. To control aphids, natural enemies could be an option but their efficacy is sometimes limited by their dispersal in natural environment. Here we report the first isolation of a bacterium from the pea aphid Acyrthosiphon pisum honeydew, Staphylococcus sciuri, which acts as a kairomone enhancing ...

Red palm weevil, Rhynchophorus ferrugineus (Coleoptera: Curculionidae) is a key pest of palm-based ecosystem. Globally R. reported from 50 countries infecting 40 species. are attracted to wounded, damaged, dying palms or apparently healthy palms. gains entry into when female weevils drawn tissue volatiles lay eggs. The females use the rostrum bore form hole for oviposition. Because its cryptic ...

Female Anopheles gambiae were more likely to oviposit when they mated with males that were two days old than when they mated with older males. The females' age at the time of mating and blood feeding did not influence ovipositional patterns. Females were no less likely to oviposit when they mated after blood feeding and maturing eggs. Sperm were present in the seminal vesicles of males 28 hours...

Ovipositional preference and larval survival of the diamondback moth, Plutella xylostella (L.), were compared among cabbage, Brassica oleracea L. variety capitata; glossy collards, Brassica oleracea L. variety acephala; and yellow rocket, Barbarea vulgaris (R. Br.) variety arcuata in different treatments of planting density, host plant age, intercropping, and water stress in 2003 and 2004. P. x...
