Solenopsis mealybug, (Phenacoccus solenopsis) infests cotton at Perambalur district of Tamil Nadu. During the surveys carried out during 2008-10, coccinellids Scymnus nubilus Mulsant, Hyperaspis maindroni Sicard, green lacewing, spiders, Aenasius bambawalei Hayat, Homalotylus eytelwenii Ratzeburg (Encyrtidae) Promuscidea unfasciativentris Girault and Coccophagus sp. (Aphelinidae) were recorded. The per cent emergence of S. nubilus was highest (68%) during second week of February and lowest (6%) during last week of November. The highest percentage (18%) of H. maindroni was recorded during second week of February and lowest (2%) during third week of March. The highest parasitisation (76%) by A. bambawalei was recorded during last week of February whereas it was lowest (8%) during last week of December. Similarly, the highest parasitisation (28%) by P. unfasciativentris was recorded during third week of February whereas it was lowest (2%) during third week of March. But the percent parasitized mealybug by Coccophagus sp. was very lower than others. A. bambawalei and P. unfasciativentris were most common parasitoids on mealybug P. solenopsis in cotton.Keywords

Field trials were conducted on the releases of Cotesia flavipes Cameron (Indonesian strain) against sugarcane stalk (Chilo auricilius Dudg.) and internode (Chilo sacchariphagus indicus Kapur) borers at IISR Farm, Lucknow for consecutive three crop seasons 1996-97 to 1998-99. The parasitoids were released in one block @ 2000 mated females/ha/month split into four doses from July to October and the other block was treated as check. The results indicated reduction of 56.2, 69.6 and 43.1 per cent in stalk borer infestation in parasitoid released blocks as compared to check, in October during 1996-97, 1997-98 and 1998-99, respectively. The results remained inconclusive in cases of internode borer due to low infestation.Keywords

Laboratory investigations were carried out on rearing, biology, host stage suitability and storage of Indonesian strain of larval parasitoid Cotesiaflavipes (Cameron) using Chilo auricilius Dudgeon as a host. The parasitoid could be successfully reared on larvae of C. auricilius for 11 successive generations without affecting the biotic potential greatly. Adults of C. flavipes lived for 8.7±3.3 (male) and 5.4±2.3 (female) days. The egg + larval, cocoon and total developmental periods of the parasitoid were 15.2±0.3, 8.5±0.3 and 23.7±0.4 days, respectively. Third to fifth instar larvae of C. auricilius were significantly more preferred for oviposition wherein they completed their development successfully. Three day old cocoons could be stored at 10°C for 15 days with 71.6 per cent emergence.Keywords

Elasmus zehntneri Ferriere a larval parasitoid of the sugarcane top borer, Scirpophaga excerptalis Walker has been reported from different states of the Indian Union. Gupta (1954) reported its parasitisation to range between 5 to 6 per cent from January to May in Uttar Pradesh, Bihar and Punjab and 10 to 15 per cent from July to September in Bengal and Maharashtra (Erstwhile Bombay) states.Keywords

Field evaluation of the exotic larval parasitoid, Allorhogas pyralophagus Marsh was carried out under field conditions at the Indian Institute of Sugarcane Research (IISR) farm (Lucknow), Simbhaoli (Gbaziabad) and Majethia Farm (Sardarnagar) against the larvae of the top borer, Scirpophaga excerptalis Walker. The recovery of the released parasite was poor and only a few cocoon masses of released parasite were recovered at IISR farm and Simbbaoli. The parasite, in spite of repeated releases for many years could not be established in the released areas. Parasitation and emergence behaviour of the wasp was also studied under laboratory conditions using field-coHected top borer - Infested canes. The wasp parasftised the top borer larva In the cane through the silken covering present over the slit formed during feeding of host larva. The wasp, after completing its development on host larva, emerged through tbe same silt.
