INSECTS NOT KNOWN TO OCCUR IN THE UNITED STATES RED PUMPKIN BUG (Coridius janus (Fabricius)) Economic Importance - This pentatomid has caused severe damage to pumpkins in India, pumpkins and gourds in Burma, and is a major pest of several cucurbits in West Pakistan. It also attacks egg- plant, melon, and beans. The nymphs and adults are gregarious and often become so numerous as to almost cover the host plant. A heavily infested plant wilts and may die due to the large amount of sap sucked from the stem and leafstalks by both nymphs and adults. Distribution - Burma, India, Ceylon, and West General Distribution of Red Pumpkin Bug Hosts - Principally a pest of cucurbits including pumpkin, gourd, melon, and cucumber. It has also been recorded on eggplant and beans. Life History and Habits - These bugs overwinter as adults, emerg- ing around mid-May. Mating takes place only once a year, this occuring during the rainy season, July to September. Oviposition begins 3-4 days after mating, with each female capable of pro- ducing up to 100 eggs. The eggs are laid in strings of 18-20 on the ventral surface of the leaves of the host plant. The ventral side of the leaves are rough and hairy which probably aids in keeping the eggs from falling to the ground. The average incuba- tion period is 5-6 days. There are 5 nymphal instars which require a total of 23-29 days to mature. The adults do not fly extensively and congregate on the host with the nymphs. Both stages suck the sap from the plant causing it to wilt and die. Hemiptera:Pentatomidae No. 194 of Series - 197 -.
