Long‐term impact of exposure to Royal Guard, a pyriproxyfen‐based bed net, on pyrethroid‐resistant malaria vectors from Cameroon using DNA‐based metabolic resistance markers

open access: yesPest Management Science, Volume 81, Issue 4, Page 2165-2180, April 2025.
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]

open access: yesJournal of Experimental Biology, 1941
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.

The impact of low erythrocyte density in human blood on the fitness and energetic reserves of the African malaria vector Anopheles gambiae [PDF]

open access: yes, 2013
Background Anaemia is a common health problem in the developing world. This condition is characterized by a reduction in erythrocyte density, primarily from malnutrition and/or infectious diseases such as malaria.

Attraction of cabbage stem flea beetle (Psylliodes chrysocephala) to host plant odors

open access: yesPest Management Science, EarlyView.
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

open access: yesPest Management Science, Volume 81, Issue 7, Page 3548-3556, July 2025.
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 larval diet on female reproductive output of the European coccinellid Adalia bipunctata and the invasive species Harmonia axyridis (Coleoptera: Coccinellidae)

open access: yesEuropean Journal of Entomology, 2008
Cannibalism and intraguild predation (IGP) are both common phenomena amongst aphidophagous coccinellids and serve as vital alternative feeding strategies which can prolong survival during periods of aphid scarcity.

Effects of prescribed fire on Cope’s Gray Treefrog (Hyla chrysoscelis) across habitat scales and life stages [PDF]

open access: yes, 2017
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 fertilization in maize increases attractiveness of nocturnal herbivore‐induced plant volatiles to Spodoptera frugiperda natural enemies

open access: yesPest Management Science, EarlyView.
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 ...

Comparative behavioral and EAG responses of female obliquebanded and redbanded leafroller moths (Lepidoptera: Tortricidae) to their sex pheromone components

open access: yesEuropean Journal of Entomology, 2007
Studies were conducted investigating the responses of female obliquebanded leafrollers, Choristoneura rosaceana (Harris) and redbanded leafrollers, Argyrotaenia velutinana (Walker) (Lepidoptera: Tortricidae), to components of their sex pheromone ...
