| Abstract | ||||
| The effect of host plants(rose and broad bean ) on the developmental of the hairy rose beetle insect, Tropinota squalida Scop.immatureand mature stages were studied under laboratory conditions (25±2oCand 70±5% R.H).The incubation period of T. squalida eggs, larval duration on both tested host plant was approximately the same. The shortest duration of pupal stages( male and female)was(29.20± 0.8,and 27.1± 0.5 day)when reared on rose followed by(35.20±0.9and32.85±0.87day) on broad bean. There are significant differences in duration between the pupal stages which reard on rose and broad bean . Total immature stages of T. squalid female and male lasted (118.65±0.9&129.43±2.3day)for female and(112.00±0.80 &119.35±0.96day) for male on rose and broad bean respectively . There significant are difference in duration between the total immature stages which reard hosts plant).Adult female and male longevity reared on rose was significantly longer than those on broad bean .the average number of deposited eggs /female was significantly affected by host plant .However, , female fed on rose laid an average of 30.3 eggs with a daily mean 0.65, while on broad bean, female laid an average of 24.5 eggs with a daily mean 0.58 eggs. | ||||
