Abstract

The biology of pentatomid bug Halyomorphia marmorea F. which causes tender nut drop in arecanut has been studied. The investigations were conducted during poist-monsoon seasons of 1985 and 1986. Under laboratory conditions, the female and male bugs lived for 38.0 and 33.8 days, respectively. Fe-males laid, on an average, 4 egg clusters, each comprising 28 eggs. The incubation period varied from 4-6 days with an average of 5.1 days. There were five nymphal instars each with an average duration of 3.7, 6.1, 5.1, 6.5 and 9.3 days, respectively. The description of different instars is furnished in detail. The nature and extent of damage to arecanut and host range of this pentatomid bug are also discussed.
