DEET‐cyclodextrin inclusion complexes for mosquito and tick repellency: Extended repellency time and no zebrafish embryotoxicity

open access: yesPest Management Science, EarlyView.
Hydroxypropyl‐β‐cyclodextrin (HPβCD)–N,N‐diethyl‐meta‐toluamide (DEET) complex extended tick repellency to 168 h. Full protection against Aedes aegypti for 7 h with HPβCD‐DEET. HPβCD reduced DEET release and skin retention significantly. No embryotoxicity observed below 325 mg L−1 in zebrafish model.

SOME OBSERVATIONS ON OVIPOSITION IN THE FOWL [PDF]

open access: yesQuarterly Journal of Experimental Physiology and Cognate Medical Sciences, 1953
1. Six out of nine hens were able to lay their eggs after spinal transections, but the process took much longer than normal.2. Ovulation was almost completely inhibited in the spinal birds.3. Observations at laparotomy show that during oviposition the uterus is not everted as claimed by Wickmann, but that the egg passes from the uterus into the vagina ...

Behavioural manipulation of the cabbage stem flea beetle (Psylliodes chrysocephala L): Prospects for push–pull strategies in oilseed rape

open access: yesPest Management Science, EarlyView.
Behavioural manipulation of Psylliodes chrysocephala provides promising opportunities for sustainable pest management in oilseed rape systems. This review synthesises evidence on glucosinolates and their volatile isothiocyanate derivatives as phagostimulants and attractants, alongside the repellent or antifeedant effects of non‐host plants, plant ...

Behavioral responses of adult female tobacco hornworms, Manduca sexta, to hostplant volatiles change with age and mating status

open access: yesJournal of Insect Science, 2002
We present evidence for two behaviors influenced by intact, vegetative plant odor -- upwind flight and abdomen curling -- in female Manduca sexta and demonstrate the influence of the age and mating status of the moths on these behaviors.

Electrophysiological Responses and Reproductive Behavior of Fall Webworm Moths (Hyphantria cunea Drury) are Influenced by Volatile Compounds from Its Mulberry Host (Morus alba L.)

open access: yesInsects, 2016
Hyphantria cunea (Drury) is an invasive pest of Morus alba L. in China. β-ocimene and cis-2-penten-1-ol among eleven electro-physiologically active leaf volatiles from M.

Microbiome‐mediated chemical communication in insects: Implications for pest management

open access: yesPest Management Science, EarlyView.
Microbiome–semiochemical interactions involve the following processes: direct microbial synthesis, host gene regulation, precursor biotransformation, microbiome modulation and indirect ecological signaling. Abstract Insects rely on semiochemicals to regulate aggregation, mating, foraging, and host selection. This review synthesizes evidence that insect‐

Oviposition of the invasive two-spotted leafhopper on an endemic tree: Effects of an alien weed, foliar pubescence, and habitat humidity

open access: yesJournal of Insect Science, 2004
The two-spotted leafhopper, Sophonia rufofascia (Kuoh and Kuoh), is an exotic pest from South-East Asia that attacks a wide variety of plant species in Hawaii.

The role of urea in the oviposition behaviour of Japanese encephalitis vectors in rice fields of South India

open access: yesMemorias do Instituto Oswaldo Cruz, 2003
The effect of urea on the oviposition behaviour of culicine vectors of Japanese encephalitis was studied in rice fields. Gravid females had a strong preference for oviposition in urea treated areas in rice fields, while no such preference was exhibited ...

Intercropping with legumes can reduce insect pest pressure but does not increase yield in winter oilseed rape (Brassica napus L.)

open access: yesPest Management Science, EarlyView.
Intercropping winter oilseed rape with spring faba bean reduced cabbage stem flea beetle and pollen beetle damage but also reduced crop yield. Sowing the intercrop simultaneously with winter oilseed rape was essential to maximize crop protection against cabbage stem flea beetles. Abstract BACKGROUND Winter oilseed rape (WOSR, Brassica napus) is a major

Variation of the Oviposition Preferences of Aedes aegypti in Function of Substratum and Humidity

open access: yesMemorias do Instituto Oswaldo Cruz, 2002
Two Aedes aegypti (L.) populations were studied in the laboratory regarding the preference for three types of breeding sites, i.e., flasks containing only water, flasks with a plant and flasks with a stick.
