Drosophila Melanogaster Oviposition and Toxicity Studies on a Chip
Oviposition or egg-laying is an important behaviour used to assess the biological processes in Drosophila melanogaster. This behaviour is affected by physical and chemical properties of the substrate, which have not been investigated precisely and parametrically with existing manual approaches. …

Investigations into the oviposition behaviour of the mosquito Anopheles gambiae
… vectors in sub-Saharan Africa. How they locate oviposition sites is not fully known, but a greater understanding of this subject may lead to more effective monitoring and trapping of gravid females. This project investigated potential oviposition semiochemicals and the oviposition behaviour of …

Calliphorid Hygrosensation Perception and the Effect of Humidity on Oviposition Behavior
… conditions, such as humidity, have inhibited oviposition. While the effects of temperature on blow fly behavior are well established, humidity remains less understood. This research examined the oviposition behavior of Phormia regina (Diptera: Calliphoridae) under varying humidity levels …

Effects of Water Parameters on Container Mosquito (Diptera: Culicidae) Oviposition and Performance
… under differing depth and larvae densities. Oviposition studies showed that <em>Ae. albopictus </em>had a preference for deeper habitats (χ<sup>2</sup>= 14.2902, p= 0.0139) but did not prefer any surface areas (χ<sup>2</sup>= 7.2321, p= 0.0649) though there was a trend that indicated that …

Daily patterns of oviposition mediate sexual conflict in a polygynandrous mating system
… sexual conflict. However, little is known about oviposition behaviour or how it affects male/female interactions. In this study, I observed and quantified oviposition behaviour, tested whether the absence of males affected the temporal pattern of oviposition, and looked for relationships between …

Oviposition Site Selection By Mosquitoes: Predator-Released Kairomones And Responses To Different Taxa
Oviposition site selection is a critical reproductive behavior for egg-laying organisms that offer little to no parental care. Determining the mechanisms females use to assess sites is critical to understanding life history traits, community structure, and species interactions. Mosquitoes are …

Oviposition Preferences for Infusion-Baited Traps and Seasonal Abundance of Culex Mosquitoes in Southwestern Virginia
… Virginia to determine the bionomics and ovipositional preferences of Culex restuans Theobald and Culex pipiens Linnaeus using ovitraps and gravid traps. Both species have been implicated as enzootic and epizootic vectors of West Nile virus (WNV) and these studies provide information on …

Oviposition behaviour of Neltumius arizonensis Schaeffer (Coleoptera: Bruchidae) : a biological control agent of Prosopis spp. in South Africa
… of this study was to examine and quantify the oviposition behaviour of N. arizonensis females under different conditions to determine whether eggs of conspecifics or of another bruchid species, Algarobius prosopis (LeConte), affected oviposition. Diet, the number of mates, the duration of …

Morphological differentiation of eggs and comparative efficacy of oviposition and gravid traps for Aedes vectors at different habitats
… understand the efficacy of gravid traps and oviposition traps as surveillance methods for these mosquitoes, field studies were conducted in three different habitat types. Ae. triseriatus, Ae. albopictus, Ae. japonicus, and Aedes aegypti eggs were described with the aid of color images and …

Fine structure of the ovipositor and studies of feeding and oviposition site selection by the serpentine leafminer, Liriomyza trifolii (Burgess) (Diptera: Agromyzidae)
… the suitability of a host plant for feeding, oviposition, and subsequent larval development. Two greenhouse experiments were conducted to evaluate the effects of photoperiod and application of plant growth regulators on two factors: 1) feeding and oviposition site selection and 2) spatial …
