Bioecology of pyrrochorid plant bug Iphita limbata (Stal)

Abstract :

Iphita limbata is a macropterous but flightless, phytophagous bug feeding on the seeds of Sterculia foetida. The studies on bio-ecology, activity pattern and sexual dimorphism in Iphita limbata from specified areas of Madras Christian College, Tambaram reveals that the occurrences of males were more than the females. Predominant mating behavior was found during the months of late December, January and February during which females were in mated condition. Iphita limbata prefers a relatively high humidity and an optimum temperature of 36.1°C for the population to flourish. The activity of Iphita limbata was found to be closely correlated to environment parameters especially temperature. The males are smaller than females. The reproductive organs of males consist of a pair of testis connected with paired seminal vesicle and a median ejaculatory duct; females consist of 7 pairs of teleotrohic ovarioles on either side of the alimentary canal with a spermatheca
