Assessment on Biological and Morphometric Parameters of Jatropha Leaf Webber Cum Fruit Webber, Pempelia morosalis (Saalm Uller) along with Associated Natural Enemies in Eastern Uttar Pradesh of India

Abstract:
The present investigation was conducted in Biocontrol laboratory of the Department of Entomology and Agricultural zoology, Institute of Agricultural Sciences, BHU, Varanasi to study growth and development of Pempelia morosalis (Saalm Uller) on Jatropha under laboratory conditions during April 2009 to May 2010. The studies were conducted at constant temperature of 27±2°C and 75% relative humidity. All observations of biological and morphometric parameters were replicated 6 times up to successive three generations results revealed that a single female of Pempelia morosalis laid 41 to 60 eggs during the life span. Eggs were whitish, flat, oval to round, often in groups of 8 to 15. Eggs were hatched into larvae within 5 to 7 days. First and second instar larvae were plain, pale yellowish green colour that were changed to brown during third instar to fifth instar with dorsal longitudinal stripes. Larval development was completed in 25 to 30 days. Pupal period lasted for 7 to 8 days. The newly emerged adult was grey in colour with snout like labial palp in the head with hyaline hindwing. Male was slightly smaller than female with pointed abdominal tip. The average longevity of male and female was 5 to 6 and 7 to 8 days, respectively. Two parasitoids were found on leaf webber larvae i.e., Bracon hebetor (Say) and Tachinid sp. Both parasitoids were successfully completed their biology on 4th instar larvae of P. morosalis. On providing two leaf webber larvae for a pair of B. hebetor, a total of 36 to 49 individual parasitoids were obtained, whereas in case of Tachinid sp., a total of 21 to 37 individual parasitoids were obtained in research study.
