Population Genetic Structure and Geometric Morphology of Codling Moth Populations from Different Management Systems

Codling moth management and chemical ecology.

Lepidopteran insects use sex pheromones to communicate for mating. Olfactory communication and mate-finding can be prevented by permeating the atmosphere with synthetic pheromone. Pheromone-mediated mating disruption has become a commercially viable pest management technique and is used to control the codling moth, Cydia pomonella, a key insect pest of apple, on 160,000 ha worldwide. The codlin...

Biological and genetic differences between populations of diamondback moth from different geographic origins

The diamondback moth, Plutella xylostella (Lepidoptera: Yponomeutidae), is a major pest of Brassicaceae and has a worldwide distribution. Biological and genetic differences were studied between populations native to South Africa, Benin, Brazil, France, Japan, United States, Martinique, Réunion Island, Uzbekistan and five localities in Australia. To observe the variability of oviposition behavio...

Resistance Management Update on Organophosphate Resistance in Codling Moth

In 2003, organophosphate (Guthion) resistance was surveyed in codling moth from populations throughout Washington State. Populations were collected using pheromone traps during first and second flights from apple and pear and sampled for Guthion resistance using the standard adult topical bioassay. Select populations were also sampled for pyrethroid and chloronicotinyl resistance. All orchards ...

Measuring local genetic variability in populations of codling moth (Lepidoptera: Tortricidae) across an unmanaged and commercial orchard interface.

The genetic structure of adult codling moth, Cydia pomonella (L.), populations was characterized both inside a managed apple, Malus domestica Borkdhausen, orchard and in surrounding unmanaged hosts and nonhost trees in central Chile during 2006-2007. Adult males were collected using an array of sex pheromone-baited traps. Five microsatellite genetic markers were used to study the population gen...
