Dried apricot is one of the stored fruit most endangered to be infested by the Indianmeal moth, Plodia interpunctella (Hübner). The aim of the present study was to identify volatile compounds from dried apricot that elicit an electrophysiological response in P. interpunctella adults. The volatiles were collected from the headspace of a glass vial with dried apricots using closed-loop-stripping ...

1. Cyclic dynamics of various periods are pervasive in many insect populations where interactions with natural enemies are known to be important. How stage-structured processes within the host population, such as competition and cannibalism, affect these interactions has received little attention so far. 2. Using the well-studied laboratory host–parasitoid system of Plodia interpunctella and Ve...

Concerns over insect resistance, regulatory action, and the needs of organic processors have generated renewed interest in developing nonchemical alternative postharvest treatments to fumigants used on dried fruits and nuts. Low-temperature storage has been identified as one alternative for the Indianmeal moth, Plodia interpunctella (Hiibner), and navel orangeworm, Amyelois transitella (Walker)...

1. Animals raised in good environmental conditions are expected to have more resources to invest in immunity than those raised in poor conditions. Variation in immune activity and parasite resistance in response to changes in environmental temperature, population density and food quality have been shown in many invertebrate species. 2. Almost all studies to date have examined the effects of ind...

BACKGROUND/OBJECTIVE The Indianmeal moth Plodia interpunctella is a highly prevalent food pest in human dwellings, and has been shown to contain a number of allergens. So far, only one of these, the arginine kinase (Plo i 1) has been identified. OBJECTIVE The aim of this study was to identify further allergens and characterise these in comparison to Plo i 1. METHOD A cDNA library from whole...
