Description :
The sting bug, Canthecona furcellata Wolff. (Hemiptera: Pentatomidae) is a major pest of tropical tasar silkworm, A. mylitta. The total nymphal period of C. furcellata with an average was 20 days and the adult life span of male and female were 18.9 ± 1.260 days and 29.5 ± 1.078 days respectively. The nymphal duration and adult life span of Canthecona furcellata is long. So they feed for longer duration on tasar silkworm, hence the cocoon production much more reduced due to its regular presence in tasar plantations. The egg laying capacity of C. furcellata with an average 28.6 ± 2.826 eggs per batch and 260.4 ± 44.873 eggs per female during her life span. The pre-copulation and copulation period of pentatomid bug varied from 5 - 7 days and 12.45 ± 0.368 hr. respectively as well as the oviposition period was 16.2 ± 1.594 days recorded.
