A laboratory study was carried out on biology of sugarcane woolly aphid (SWA) predator, Dipha aphidivora Meyrick (Lepidoptera: Pyralidae). Dipha aphidivora occupied 5.6 ± 0.81, 24.61 ± 3.41, 7.80 ± 0.51, 1.65 ± 0.54 and 3.89 ± 0.74 days for incubation. total larval period, pupation, longevity of adult male and female, respectively. The total life cycle lasted for 43.27 ± 5.84 days. During its total larval period of 24.61 ± 3.41 days, a single D.aphidivora consumed on an average 6,074.84 ± 87.6 sugarcane woolly aphids.Keywords

Laboratory experiments were conducted to evaluate the safety of Nomllraea rileyi to larval parasitoid, Microplitis maculipennis and honeybee, Apis cerena indica. The concentration of the fungus used was 2 x 103 conidia per liter of water and Tweens 80 (0.02%) was used as spray emulsion. The fungus proved safe to larval parasitoid and honeybees. No mortality of the larvae or adults was noticed.Keywords

Cotesia ruficrus (Hal.) took a period of 16.1 days from oviposition to adult emergence. Oviposition to larval egression took 1 ].9 days and pupal period for 4.1 days. Adults survived for 12.26 (females) and 8.1 (males) days with food. Without food they did not thrive beyond 2.2 days. Sex-ratio with male dominance was 1.0: 1.4 (F: M).Keywords

Larvae of cotton bollworm, Helicoverpa armigera (Hiibner) resistant and susceptible to fenvalerate and endosulfan were tested for susceptibility to a nuclear polyhedrosis virus. The LC50 values were less in resistant strains than in susceptible. The resistance ratio to HaNPV was highest in fenvalerate resistant strain (0.88) followed by endosulfan resistant (0.64) strain.Keywords

Surveillance studies conducted on the sorghum armyworm Mythimna separata (Walker) and its natural enemies revealed that the pest actively was from June to December during 1992 and up to October during 1993. The activity attained peak during September with 59.42 and 34.25 per cent incidence during 1992 and 1993, respectively. Nine parasitoids were recorded parasitizing 18.16 and 17.55 per cent larvae during 1992 and 1993, respectively. The parasitoids Pseudogonia sp., Compsiiura sp. and Goryphus sp. were active in the early part of the season which were followed by Cotesia ruficrus and Exorista xanthaspis in the middle of the season (September-October). Correlation studies on parasitism indicated significant positi ve correlation with maximum temperature (r=0.645) and significant negati ve correlation with minimum relative humidity (r=-0.693) during 1992 and non significant correlation with abiotic factors during 1993.Keywords

In laboratory tests, Amblyseius ovalls (Evans) at 1:25, 1:50 and 1:100 predator-prey ratios eliminated Polyphagotarsonemus latus (Banks) on 9th, 12th and 17th day respectively, but could not check the muItiplication or prey at 1:I50 ratio.Keywords
