Quantifying the Impact of Parasitoids on Diamondback Moth
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 i...
متن کاملHymenopterous 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 کاملHost specificity assessments of Cotesia plutellae, a parasitoid of diamondback moth
Cotesia plutellae is being assessed as a potential biological control agent for introduction against Plutella xylostella in New Zealand. As the literature on C. plutellae provided variable assessments of its host specificity, further information was collected from the laboratory and field. Our field assessments in Fiji indicated that this parasitoid did not attack other Lepidoptera in or around...
متن کاملpostnatal studies of bats (pipistrellus kuhlii and miniopterus schreibersii) & histomorphology and histochemistry studies of organs and diseases of (neurergus microspilotus and n. kaiseri)
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
