Effect of different lining paper materials and infusions on oviposition preference of Aedes aegypti (Diptera: Culicidae) gravid mosquitoes

open access: yesScientific Reports
Aedes aegypti (Linnaeus) mosquito is a vector responsible for increasing global public health concerns due to its rapid geographical spread and increasing vectorial capacity. Understanding the breeding behavior of Ae.

Comparative susceptibility of different legume seeds to infestation by cowpea bruchid Callosobruchus maculatus (F.) (Coleoptera: Chrysomelidae)

open access: yesPlant Protection Science, 2009
The comparative susceptibility of seeds of ten legumes to infestation by Callosobruchus maculatus was studied in choice and no-choice experiments. Cowpea, garden pea and pigeon pea seeds recorded the significantly highest number of eggs oviposited and ...

Swallowtail Butterflies Use Multiple Visual Cues to Select Oviposition Sites

open access: yesInsects, 2021
Flower-foraging Japanese yellow swallowtail butterflies, Papilio xuthus, exhibit sophisticated visual abilities. When ovipositing, females presumably attempt to select suitable leaves to support the growth of their larval offspring.

Butterfly fitness under changing food qualities [PDF]

open access: yes, 2014
The present thesis investigates how different food qualities over the whole life cycle and across generations affect butterfly development and reproduction, and addresses the following main questions: (1) What effects have varying nitrogen ...

Viability analysis and the importance of fine‐scale variables influencing roadkills of a toad population

open access: yesThe Journal of Wildlife Management, EarlyView.
Fine‐scale population variables better explain roadkill patterns in natterjack toads (Epidalea calamita) than habitat proxies, with mortality driven mainly by local abundance, reduced by roadside embankments, and decreasing as the season advanced. Despite high roadkills, population viability analyses indicate no immediate extinction risk under current ...

A note on the mosquito oviposition pheromone

open access: yes, 1989
Mosquitoes of the genus Culex, e.g. Culex quinquefasciatus, release a volatile pheromone from their eggs that induces gravid females to oviposit around the pheromone source.

Coexisting ant species differ in ability to meet their intrinsic nutritional needs

open access: yesOikos, EarlyView.
Coexisting species are often assumed to reduce competition by foraging for foods that differ in nutrient composition, but few studies test whether field nutritional differences correspond to intrinsic differences in macronutrient selectivity. We compared field estimates of worker trophic position (tissue isotopes: δ15N) and worker tissue stoichiometry (

Feeding-induced rearrangement of green leaf volatiles reduces moth oviposition

open access: yeseLife, 2013
The ability to decrypt volatile plant signals is essential if herbivorous insects are to optimize their choice of host plants for their offspring. Green leaf volatiles (GLVs) constitute a widespread group of defensive plant volatiles that convey a ...

Deposition and longevity of oviposition-deterring pheromone in the cabbage seed weevil

open access: yes, 1991
The cabbage seed weevil (Ceutorhynchus assimilis Payk.) lays eggs singly into pods of oilseed rape (Brassica napus L.) through punctures bored with the mouthparts, preferring pods not recently used for oviposition.
