LIFE HISTORY AND LABORATORY REARING OF EMESAYA B. BREVIPENNIS (HETEROPTERA: REDUVIIDAE) IN SOUTHERN ILLINOIS
Abstract
The life history of Emesaya b. brevipennis (Say) was studied in southern Illinois from April to December 1998. The bug also was reared in the laboratory on Drosophila sp. at 26 ± 3.0°C under a 16:8 (L:D) photoperiod. This bivoltine species apparently overwintered as eggs. First instars were found primarily from early to late May and mid-July to mid-August, second instars from late May to early June and from late July to mid-August, third instars from late May to mid-June and during August, fourth instars primarily from early June to early July and early to late August, fifth instars primarily from mid-June to mid-September, and adults from late June to early December. In the laboratory, the incubation period averaged 33.91 d. The five nymphal stadia averaged 11.27, 7.84, 8.85, 11.14, and 16.75 d, respectively. Total developmental time averaged 89.76 d.Downloads
