Biological pest control with mass-produced arthropod natural enemies is well developed in greenhouse crops and has often resulted in the evolution of complex ecosystems with persistent populations of multiple arthropod natural enemy species. However, there are cases where arthropod natural enemies are either not effective enough, not available, or their use(More)
21 Mate recognition in animals evolves during niche adaptation and involves habitat and 22 social olfactory signals. Drosophila melanogaster is attracted to fermenting fruit for 23 feeding and egg-laying. We show that, in addition, female flies release a pheromone (Z)24 4-undecenal (Z4-11Al), that elicits flight attraction in both sexes. The biosynthetic 25(More)

Understanding how insects recognize these signals is a current challenge in chemical ecology research.(More)
Transgenic Lilium lines have been generated by Agrobacterium -mediated transformation that have enhanced resistance to Botrytis cinerea as a consequence of ectopic expression of a rice chitinase gene. The production of ornamentals is an important global industry, with Lilium being one of the six major bulb crops in the world. The international trade in(More)
Olfaction and gustation play critical roles in the life history of insects, mediating vital behaviors such as food, mate and host seeking. Chemosensory receptor proteins, including odorant receptors (ORs), gustatory receptors (GRs) and ionotropic receptors (IRs) function to interface the insect with its chemical environment. Codling moth, Cydia pomonella,(More)
Insect olfactory receptors (ORs) are tuned to volatile chemicals, they are expressed in the membrane of olfactory sensory neurons (OSNs), housed in sensilla on the antenna. The olfactory apparatus is under strong selection and ORs are tuned to vital chemical signals, mediating social communication, feeding and oviposition, and avoidance of predators and(More)

Olfaction plays a dominant role in the mate-finding and host selection behaviours of the codling moth (Cydia pomonella), an important pest of apple, pear and walnut orchards worldwide. Antennal transcriptome analysis revealed a number of abundantly expressed genes related to the moth olfactory system, including those encoding the olfactory receptors (ORs)(More)
Mate finding and recognition in animals evolves during niche adaptation and involves social signals and habitat cues. Drosophila melanogaster and related species are known to be attracted to fermenting fruit for feeding and egg-laying, which poses the question of whether species-specific fly odours contribute to long-range premating communication. We have(More)
Insects use chemical signals to find mates, food and oviposition sites. The main chemoreceptor gene families comprise odorant receptors (ORs), ionotropic receptors (IRs) and gustatory receptors (GRs). Understanding the evolution of these receptors as well as their function will assist in advancing our knowledge of how chemical stimuli are perceived and may(More)
