The effects of 2 benzoylphenylurea insect growth regulators, OMS 2017 and diflubenzuron, on 4th instar larvae of Aedes aegypti were investigated in the laboratory. Apart from delayed lethal action, possible effects on the reproductive potential were also studied. A baseline concentration of each compound causing 30% emergence inhibition was determined. At this concentration, OMS 2017 affected fecundity of the mosquito but diflubenzuron did not. The fertility of females that survived OMS 2017 exposure also was decreased; 23% of the eggs reached the 4th larval instar. Diflubenzuron did not cause any reduction in fertility. The basal follicle number showed great variability after both treatments as it was alternatively equal, lower, or higher than in the control.
在实验室中研究了两种苯甲酰脲类昆虫生长调节剂OMS 2017和敌敌畏对埃及伊蚊四龄幼虫的影响。除了延迟致死作用外，还研究了其对繁殖潜力的可能影响。确定了每种化合物导致30%羽化抑制的基线浓度。在此浓度下，OMS 2017影响蚊子的繁殖力，但敌敌畏没有。在OMS 2017暴露中存活下来的雌性蚊子的生育力也有所下降；23%的卵发育到四龄幼虫。敌敌畏没有导致生育力的任何降低。两种处理后基础卵泡数量变化很大，因为它有时与对照相等、低于或高于对照。
