We used recently detected P450 DNA‐based markers of pyrethroid resistance in both Anopheles funestus and Anopheles gambiae to demonstrate that although pyrethroid‐resistant mosquitoes have higher ability to survive and live longer after exposure to Royal Guard, this net significantly affects their lifespan, blood feeding ability and interestingly ...

Ovulation and Oviposition in Anura [PDF]
ABSTRACT The normal rhythm of sexual activity of both Xenopus and Rana is controlled by secretions of the anterior lobe pituitary. Progesterone and testosterone, as well as extracts of A.L.P., evoke ovulation in normal and hypophysectomized Xenopus.

Attraction of cabbage stem flea beetle (Psylliodes chrysocephala) to host plant odors
Oilseed rape (Brassica napus, OSR) cultivation in Europe is threatened by the cabbage stem flea beetle (Psylliodes chrysocephala, CSFB). Limited management options due to resistance and environmental concerns necessitate innovative control strategies. This study explores CSFB responses to volatile organic compounds (VOCs) emitted by host and non‐host ...

Factors affecting detection and trapping efficacy of Mediterranean fruit flies
Trapping efficacy for medfly and other fruit flies depends on environmental factors, with ambient conditions having the strongest effect. Cold acclimation can skew population estimates, making careful data interpretation essential for accurate population assessments and early detection of invasive pests.

Effects of prescribed fire on Cope’s Gray Treefrog (Hyla chrysoscelis) across habitat scales and life stages [PDF]
Fire may alter both aquatic and terrestrial habitat used by all amphibian life stages, yet, our knowledge of its effects on amphibians is primarily limited to adult responses. I present an integrated approach to test the response of Cope’s Gray Treefrog (

Silicon (Si) fertilization enhances the attractiveness of plant volatiles emitted by fall armyworm‐infested maize plant to the predatory earwig Doru luteipes by triggering the emission of the terpene neryl acetate. Abstract BACKGROUND Silicon (Si) fertilization has been well‐documented to enhance plant resistance against insect pests by increasing the ...
