The biology of four species of aphidophagous syrphids, namely, Paragus serratus (F.), Episyrphus balteatus (De Geer), Ischiodon scutellaris (F.) and Dideopsis aegrota (F.) was studied on guava aphid, Aphis gossypii Glover, during 2007-08 and all the four species successfully completed their life cycle on A. gossypii. P. serratus had the shortest life cycle on A. gossypii with a total developmental period of 20.7 ± 1.36 days, followed by E. balteatus (21.5 ± 1.17 days), I. scutellaris (21.8 ± 0.91 days) and D. aegrota (26.3 ± 1.08 days). The total larval period of P. serratus, I. scutellaris, E. balteatus and D. aegrota averaged 9.8 ± 0.82, 10.6 ± 0.43, 10.0 ± 0.56 and 11.2 ± 0.64 days, respectively. The pupal period, fecundity and longevity of the syrphids on A. gossypii were recorded. In order to complete the larval period, each larva of P. serratus, I. scutellaris, E. balteatus and D. aegrota required a total of 333.7 ± 59.12, 380.7 ± 75.85, 410.8 ± 87.60 and 472.5 ± 56.89 numbers of A. gossypii, respectively.Keywords

Adults of Scymnus coccivora Ayyar (Coleoptera: Coccinellidae) were stored in five different temperature regimes of 5, 10, 15, 20 and 29°C along with 50 per cent honey as adult food, and the percent survival and fecundity at weekly interval were recorded during September - October 2004 in the weather condition of 31.9 ± 2.2°C and 68.8 ± 7.1 per cent relative humidity at Insectary, Department of Agricultural Entomology, Agricultural College and Research Institute, Madurai. The adult survival was 81.7 and 31.7 per cent on 35th and 56th day after storage, respectively when stored at 15°C. Adults of S. cocciwJra drawn from 20°C continued to lay eggs for up to 49 days which were 28.4, 23.4, 18.O, 15.4, 12.7, 7.4 and 4.0 eggs/female on 7, 14, 21, 28,35, 42 and 49th day after storage, respectively. Temperature at 20 and 15°C were favourable for the storage of adults with survival for prolonged period while 5 and 10°C were detrimental to survival and fecundity.Keywords
