Abstract
Survival of larvae of blackheaded fireworm, Rhopobota naevana (Hübner), was determined in two experiments where insects were submerged in water of different temperatures or dissolved oxygen content. Water temperature at high (8.2-13.1 ppm) dissolved oxygen did not affect survival significantly; 47% survived at 2°C and 41% at 10°C after 9 d. Dissolved oxygen affected survival significantly; only 7% survived in water oflow dissolved oxygen (5.1-7.1 ppm) at 10°C for 3 d compared with 91% at high dissolved oxygen (8.8-9.8 ppm). Flooding to control fireworm larvae was evaluated on three commercial cranberry marshes. A 25-50-h spring flood while vines were dormant resulted in a significant reduction of larvae. Data show that flooding may be useful to manage blackheaded fireworm.
