Abstract

Objective: To determine the sensitivity of Blattela germanica L (B. germanica L) to differenct doses of insulin.

Methods: B. germanica were reared in laboratory conditions at (25±2) °C and (50±5)% relative humidity (RH), and exposure period of 12:12 L/D. Different concentrations, viz. 5, 10, 15, 20 and 25 µ of insulin N, R, (N+R) were prepared and injected to 10 treated cockroaches with another 10 cockroaches which were injected with normal saline as control group.

Results: Insulin N with a dose of 20 µ caused more than 70% mortality of B. germanica in this study. There was a significant difference between 20 µ of insulin N with other doses of 5, 10, 15 and 25 µ, and its comparison with other forms of medication also showed obvious difference (P<0.05).

Conclusions: It can be concluded that effective drug doses of insulin which can be used as posion bait or gel against German cockroaches could be utilized in the control of B. germanica in the future field studies.

Keywords: Blattela germanica; Insectary; Insulin; Rearing; Sensitivity.
