Development of synthetic volatile attractant for male Ectropis obliqua moths

Journal of Integrative Agriculture, 2016
The tea geometrid Ectropis obliqua is one of the most serious leaf-feeding insect pests in tea (Camellia sinensis) in East Asia. Although several volatile chemicals emitted from tea plants have been reported to be attractive to E.

Use of Baited Pitfall Traps for Monitoring Pales Weevil, \u3ci\u3eHylobius Pales\u3c/i\u3e (Coleoptera: Curculionidae) [PDF]

, 2017
Pitfall traps baited with ethanol and turpentine serve as an effective tool for monitoring pales weevil (Hylobius pales) populations. Males and females are equally attracted to this bait. Neither component alone showed any attractiveness. The presence of

Ageing and sex attraction of Teratorhabditis nematode

Acta Scientiarum: Animal Sciences
Sex attraction was observed in the free - living nematode Teratorhabdits palmarum (Gerber & Giblin-Davis, 1990). Attraction by means of pheromones provides the ability to find and distinguish appropriate individual with which to mate.

Microbial Odorant Detection Guides Drosophila Parasitoids Seeking Hosts in Fermenting Fruits

Advanced Science, EarlyView.
Yeast microbes in fermenting fruits attract both host flies and their parasitoid wasps. Female Leptopilina boulardi detect yeast‐emitted ethyl esters via two olfactory receptors, LbouOR167 and LbouOR136. A conserved residue, Leu159, is critical for binding these compounds, enabling female wasps to locate host‐rich habitats.

Field Evaluation of Trap Components for the Introduced Pine Sawfly, \u3ci\u3eDiprion Similis\u3c/i\u3e (Hymenoptera: Diprionidae) [PDF]

, 2017
Three sizes of the Conrel Delta trap, a yellow cardboard tube trap, and the Pherocon II standard trap generally used in detection surveys were evaluated. Tests were run for 41 days in the summer of 1980 and 35 days in the spring of 1981.

Ecology and evolution of pyrazines in insects

Biological Reviews, EarlyView.
ABSTRACT Chemical communication is the oldest and most widespread form of signalling among and within organisms. Among the many compounds involved in such communication, pyrazines – nitrogen‐containing heterocyclic molecules – are especially intriguing due to their widespread occurrence across the tree of life, from bacteria and fungi to insects and ...

Ovulating Female of Nine‐Spined Sticklebacks (Pungitius sinensis) Are Attracted to Substances Derived From Male Kidneys

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Male sticklebacks (Gasterosteidae) produce an adhesive protein called “spiggin” in the tubular epithelial cells of their kidneys, which they use to attach plants or plant debris together and build nesting sites. Spiggin is a glycoprotein excreted in urine.

Proximity to bait and social interactions influence individual wild pig (Sus scrofa) visitation at bait sites

The Journal of Wildlife Management, EarlyView.
Individual wild pig bait site visitation and time to initial detection is primarily influenced by space use (i.e., proximity to bait) and whether wild pigs from other social groups visited before. Specifically, females are less likely to visit a bait site if an adult male visits a site before them.

Wheat fertilization affects oviposition preference of wheat midge, Sitodiplosis mosellana (Géhin) (Diptera: Cecidomyiidae)

Pest Management Science, EarlyView.
Wheat fertilization increased plant growth, nitrogen and protein levels, influencing the wheat volatile profile and affecting female wheat midge choice to lay eggs. This could partly result from the observed changes in the VOC profile. Abstract BACKGROUND In Canada, the orange wheat blossom midge (hereafter called wheat midge), Sitodiplosis mosellana ...
