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

Eocanthecona furcellata (Wolff) (Hemiptera: Pentatomidae) is an important polyphagous predator of several agricultural, horticultural and forest insect pests. The biology and feeding potential of E. furcellata were investigated on Bihar hairy caterpillar, Spilosoma obliqua (Walker), a lesser known prey under laboratory conditions. Gravid female laid on an average 203.6±12.56 eggs during its life time. Nymphs passed through five instars in 22.25 to 27.25 days and developed into adults. First instar nymphs had the shortest duration (2.5 to 3.25 days) while fourth instar took maximum days (5.5 to 6.5) to complete, while second, third and fifth instars completed in 5.07 ± 0.26, 5.20 ± 0.71 and 5.24 ± 0.39 days, respectively. Female bugs were bigger in size and lived up to 28 days, while males survived up to 18 days when fed on second instar larvae of S. obliqua. Neonate nymphs devoured 1.6 larvae of S. obliqua while second, third, fourth and fifth instar nymphs consumed 7.73, 11.93, 12.13, 18.67 larvae of S. obliqua, respectively. Individual male and female in their adult stage consumed average 84.25 and 125.5 larvae, respectively, and total consumptions were 136.31 and 177.56 larvae during their life-cycle. From the study, it is evident that S. obliqua could be used as an alternative host to mass rear E. furcellata under laboratory conditions when the main host is scarce or not available.Keywords
