The taeniaticornis -group of genus Apanteles Foerster from China is revised, in which a total 3 species are recorded and illustrated. One new species, named, A. parectangular Liu & Chen, sp. nov. described illustrated, key to Chinese the -group, provided.

-1. Tobacco hornworms, Manduca sexta, were reared on either tobacco leaves or synthetic diet. 2. Glucose and trehalose levels in the hemolymph were significantly lower in leaf-reared larvae. 3. Levels of trehalose were higher in the earlier part of each stadium. 4. Fourth stadium levels of trehalose were generally greater than fifth stadium levels. 5. Trehalose, but not glucose, levels were low...

In the comprehensive rearing of lepidopterans from peninsular India, eleven species of Lycaenidae were parasitized by ten species of wasps. Four new taxa of lycaenid associated microgastrine wasps Parapanteles eros Gupta n. sp., P. arka Gupta n. sp., P. esha Gupta n. sp., and P. regale Gupta n. sp. reared from Chilades pandava (Horsfield), Curetis thetis (Drury), Prosotas dubiosa (Semper), Taju...

The diamond back moth Plutella xylostella (L.) is the most serious pest of Brassicaceae in the world. It is resistant to many insecticides which has led to a search for alternative techniques of control, principally biocontrolbased pest management. The impact of P. xylostella and its parasitoids was analysed in a 6-month study of cabbage crops in the Brasilia region of Brazil, from June to Nove...

Surveys for Stenoma catenifer Walsingham, the avocado seed moth, and its associated larval parasitoids were conducted in the Departments of Junín, Huánuco, Cusco, and Madre de Dios in Perú. Fruit infestation levels in some areas ranged from 0 to 58%, and parasitism of S. catenifer larvae in Junín and Huánuco was 23%. Five species of hymenopteran parasitoid in two families, Braconidae (Apanteles...

A baculovirus present in the female reproductive tract of the parasitoid wasp Apanteles melanoscelus has been isolated and partially characterized. Viral DNA is double stranded, circular, and of highly variable molecular weight ranging from 2 x 10(6) to 25 x 10(6); the DNA is of homogeneous density at rho = 1.694 g/ml. Acrylamide gels resolve 18 polypeptide bands in the case of purified virions...

Investigations carried out on the parasite-hyperparasite complex of the coconut pest Opisina arenosella Walker indicate that the hyperparasites considerably reduce the population of the parasites and thus lower the efficiency of the latter as biological control agents. Over half the cocoons of the parasitoid Apanteles taragamae Vier., were parasitised by the hyperparasites, with Aphanogmus mani...
