Okine et al.: Diadegma insulare Viability after Cold Storage 503 LOW TEMPERATURE EFFECT ON VIABILITY OF DIADEGMA INSULARE (HYMENOPTERA: ICHNEUMONIDAE) PUPAE AND EFFECT OF THIS PARASITOID ON FEEDING RATE OF DIAMONDBACK MOTH LARVAE (LEPIDOPTERA: PLUTELLIDAE)

Laboratory tests with Diadegma insulare (Cresson), a parasitoid of the diamondback moth ( Plutella xylostella (L.)), were conducted to evaluate the viability of cocoons stored at 4 ° C for varying lengths of time and also the effects of parasitism by D. insulare on the feeding rate of diamondback moth larvae. The percentage of adults emerging from cocoons declined steadily with time spent in st...

Spread and global population structure of the diamondback moth Plutella xylostella (Lepidoptera: Plutellidae) and its larval parasitoids Diadegma semiclausum and Diadegma fenestrale (Hymenoptera: Ichneumonidae) based on mtDNA.

The diamondback moth (DBM) (Plutella xylostella) is one of the main pests of brassicaceous crops worldwide and shows resistance against a wide range of synthetic insecticides incurring millions of dollars in control costs every year. The DBM is a prime example of the introduction of an exotic species as a consequence of globalization. In this study we analyzed the genetic population structure o...

Comparison of Diadegma insulare (Hymenoptera: Ichneumonidae) and Microplitis plutellae (Hymenoptera: Braconidae) as biological control agents of Plutella xylostella (Lepidoptera: Plutellidae): field parasitism, insecticide susceptibility, and host-searching.

Parasitism of Plutella xylostella (L.) third and fourth instars was evaluated in a cabbage field in Geneva, NY, in 1999. Over the entire season, average parasitism was 33.6% for third instars and 53.6% for fourth instars, and the main parasitoids were Diadegma insulare (Cresson) and Microplitis plutellae Muesbeck. In the early season, total parasitism was low, and mainly caused by D. insulare. ...
