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...
