Forest edges enhance mate-finding in the European gypsy moth, Lymantria dispar
… barriers due to habitat fragmentation may reduce mate-finding ability in some species, particularly in heterogeneous landscapes containing low-density populations. This study focuses on the effects of habitat type and edge on mate-finding in an invasive defoliator, the European gypsy moth. Adult …

Modelling Allee effects in a transgenic mosquito population during range expansion
… their range into new areas, they may undergo mate-finding Allee effects such that their ability to successfully reproduce becomes difficult at low population densities. With new technology, creating target specific gene modification may now be a viable method for mosquito population control. …

Isolation and characterization of the female sex pheromone of the sugar beet cyst nematode, heterodera schachtii, and an analysis of male precopulatory behaviour /
… Characterization of the male-attractive material revealed that it was heat stable and water soluble. The aqueous medium conditioned by female H. schachtii was found to be biologically active and stimulated male behaviour in a concentration dependent manner. The activity of the crude …

COMPARATIVE GENOMICS OF CHEMOSENSORY GENE FAMILIES AMONG MEMBERS OF THE HELIOTHINAE
… insect-host plant interactions. These processes, mate-finding and acceptance, as well as host plant identification and use, strongly contribute to diversification and speciation among plant-feeding insects, including the Lepidoptera. Chloridea virescens and Chloridea subflexa are an ideal pair …

Allee effects and the persistence of small populations
… are important, as despite strong theoretical findings that a demographic Allee effect can prevent small founder population establishment, empirical evidence is limited. Additionally, social pressure is demanding alternative ‘greener’ tools to achieve eradication of new incursions. The Allee …
