This review is the first comprehensive treatment of the biology of nonfrugivorous fruit flies of the family Tephritidae. Feeding habits of destructive and useful species, morphology of immature stages, and hypotheses regarding structural homology and the evolutionary biology of nonfrugivorous tephritids are reviewed, including zoogeography and theories involving resource heterogeneity, guild st...

Although Singapore has an intensive dengue control program, dengue remains endemic with regular outbreaks. We report development and use of a novel adult oviposition trap, the Gravitrap, in managing dengue cluster areas. The Gravitrap is a simple, hay infusion-filled cylindrical trap with a sticky inner surface to serve as an oviposition site for gravid female Aedes mosquitoes. Wire gauze fitte...

Several parameters on the oviposition site preference of Aedes albopictus were studied, including color, container type, salinity, and water type. Dark-colored glass jars, especially black, blue, and red ones were preferred over light-colored jars. The black-colored ovitrap with a paper strip performed better than other types of containers. Seasoned tap water had the highest egg count when comp...

The underlying mechanisms of decision-making behaviour are poorly understood. Oviposition site selection (OSS) in the Drosophila melanogaster fruit fly provides a useful system for studying simple decision-making. OSS is influenced by both genetic and environmental variation. Variation of the foraging gene (for) is known to affect OSS. Given a choice of highand low-nutrient oviposition sites, g...

Amphibians exhibit diverse reproductive behaviors, including nine documented types of amplexus, the behavior in which male and female frogs position themselves for courtship, oviposition, fertilization. All known forms amplexus involve on top or line horizontally (cloacal apposition) with female. Here, we report a novel form observed Lau’s leaf litter toad (Leptobrachella laui; Megophryidae) Ho...

Abstract Background Olfactory cues have been shown to an important role in guiding gravid mosquito females selected sites for egg laying. The objective of this study was determine the influence emanations from soil a breeding site and putative oviposition pheromone nonane on oviposition-site selection natural populations Anopheles gambiae sensu lato (s.l.) Culex quinquefasciatus . Methods This ...

Organisms use incomplete information from local experience to assess the suitability of potential habitat sites over a wide range of spatial and temporal scales. Although ecologists have long recognized the importance of spatial scales in habitat selection, few studies have investigated the temporal scales of habitat selection. In particular, cues in the immediate environment may commonly provi...

Data in the literature have shown that treatment with caffeine (CAF) blocks development and causes death of Aedes aegypti (Ae. aegypti), in the larval stage. Since adults are not produced, CAF was considered a potential bioinsecticide, useful for controlling these mosquitoes that transmit human viral diseases. Similar results were obtained in tests with used coffee grounds (UCG). Considering th...
