The biology and behaviour of mud wasp, Sceliphron madraspatanum (Fabricius) and its possible role in insect pest management were studied under vegetable agroecosystem. The gravid female lays a single egg (2.75±0.33 mm in length) in a mud chamber that is provisioned almost exclusively with orb-weaver spiders, wolf spiders and jumping spiders available in the vegetable agroecosystem. Total numbers of spiders provisioned in each cell was negatively correlated with their mean body weight. However, the wasps avoided provisioning of lynx spider, the most predominant spider in this ecosystem, due to its short and reduced abdomen and also the presence of large, strong and erect setae over its body. In the agroecosystem, mud wasp was found to constitute the third trophic level in the food chain comprising of the vegetable crops–insect pests–spiders–S. madraspatanum and thereby their role could be detrimental for the pest management.Keywords

The seasonal incidence and biology of plume moth, Sphenarches caffer infesting bottle gourd was studied in Varanasi, Uttar Pradesh. The incidence of plume moth started from May and reached its peak during the first week of August. A solitary, larval endoparasitoid, Apanteles paludicole Cameron (Braconidae) was found to co-exist with this pest almost from beginning with peak parasitization of 40.91%. Among the biotic factors, higher parasitization by this endoparasitoid and relatively lower temperature amongst the abiotic parameters from November onwards might be responsible for the minor pest status of S. caffer on bottle gourd in this region.Keywords

Effect of nitrogen levels on the natural enemy fauna on rice variety PR118 was studied at Balloke village (Dist. Ludhiana) during kharif 2005 and 2006. The mean per cent populations of insect predators and parasitoids were higher at 103.69kg N ha−1 (225kg urea), whereas spider fauna was more abundant at higher dose of nitrogen (172.81kg N ha−1: 375kg urea). During 2005 and 2006, the overall diversity index in the crop season was higher (2.162 and 1.948, respectively) when higher dose of N was applied (172.81kg N ha−1).Keywords

Background: Investigations were carried out to record the spreading frequency of seven known endosymbionts specifically Portiera, Cardinium, Rickettsia, Fritschea, Wolbachia, Hamiltonella and Arsenophonus between the field populations of Bemisia tabaci collected from two host plants, viz. brinjal (Solanum melongena) and tomato (S. lycopersicum). Methods: Individual flies from each host were scanned for symbiotic bacterial infection with specific primers amplifying the 16S rRNA gene of Portiera, Cardinium, Hamiltonella, Rickettsia and Wolbachia, and the 23S rRNA gene of Arsenophonus and Fritschea. Findings: The primary endosymbiont, Portiera aleyrodidarum remained present in the samples of B. tabaci on both host plants brinjal and tomato but a variation was observed in the distribution frequency of secondary endosymbionts. Application: This irregular distribution of secondary endosymbionts strengthens the hypothesis that each endosymbiotic bacterium not only has a role in the survival but may also have a part in the polyphagus nature of B. tabaci.Keywords
