Quantifying the Impact of Parasitoids on Diamondback Moth
نویسندگان
چکیده
The accurate measurement of parasitoid impact on diamondback moth, Plutella xylostella (L.) populations is important to both the evaluation of exotic parasitoids for introduction, and to the integration of parasitoids with other cropping practices, particularly pesticides. Parasitoid impact is usually measured by samples for percent parasitism. Problems with the accuracy of this approach, and its application in tropical conditions, are discussed. Two other approaches, the recruitment and graphical methods, are outlined, and some data on preliminary trials with these methods are

Hymenopterous Parasitoids Associated with Diamondback Moth: the Taxonomic Dilemma
Attempts to control diamondback moth Plutella xylostella (L.) using insect parasitoids have not been entirely successful. Parasitoids which have been utilized include Diadegma species and Cotesia plutellae. A better understanding of the systematics of these Hymenoptera could lead to their more effective exploitation in biological control. Diadegma is a very large and difficult genus of lchneumo...
متن کاملSelection of Effective Species or Strains of Trichogramma Egg Parasitoids of Diamondback Moth
Twenty-seven Trichogramma and Trichogrammatoidea species or strains of different origin were tested on diamondback moth (Plutella xylostella (L.)) for host acceptance and host suitability. The experiments were conducted at 27 ± 2oC and 75-90% RH. Depending on their initial parasitization activity, the number of offspring produced and emergence ratio, 18 Trichogramrna species were identified as ...

Augmentative release of the endoparasitoid Cotesia plutellae (Kurdjumov) to control diamondback moth, Plutella xylostella (L.), in cabbage, Brassica oleracea variety capitata (L.), would be expensive for growers if done continually during a growing season. A method for establishing released parasitoids would be very beneficial in the control of this pest. One method under consideration is to us...
متن کاملParasitoids associated with the diamondback moth, Plutella xylostella (L.), in the Eastern Cape, South Africa
Seasonal fluctuations of diamondback moth and its hymenopteran parasitoids were recorded weekly from April 1997 to November 1999 at four cabbage sites in the Grahamstown area of the Eastern Cape, South Africa. Two sites were commercial farms with active spraying programmes; the others were unsprayed. Infestation levels were highest during spring (September to November) and autumn (March to May)...
متن کاملRole of Parasitoids in Managing Diamondback Moth in the Cameron Highlands, Malaysia
Three major primary parasitoids of the diamondback moth, Plutella xylostella (L.), are found in the Cameron Highlands, Malaysia. Cotesia plutellae (Kurdjumov) was discovered in the early 1970s, Diadegma semiclausum (Hellén) and Diadromus collaris (Gravenhorst) were introduced in the mid 1970s from New Zealand and Australia. Field studies in the early 1980s showed that C. plutellae was the domin...
