Effect of host plants on Sunn Pest (Eurygaster integriceps) body weight, lipid and protein content

Abstract : The Sun pest, Eurygaster integriceps Puton (Hemiptera: Scutelleridae), is a serious pest of wheat. In addition to wheat, it feeds on variety of graminous plant species including barley and rye as well as many grasses. Aim of the current study was to determine the effect of host plant on body weight, lipid and protein content of the adult Sunn pest. Results showed that host plant affected body weight of the Sunn pest. For example adult produced from nymphs grown on wheat and barley had more weight than those of rye. Also, it was observed that the adult females were produced from nymphs grown on wheat had the highest weight followed by barley and rye. Lipid content also was different based on the type of food the insect received. As can be seen the adult female were produced from nymphs grown on wheat had the highest lipid content weight followed by barley and rye. For example the amount of lipid content of the adult female grown on wheat, barley and rye was 32, 28, and 23 mg, respectively. Thus, it is concluded that host plant has profound effect on body weight, body fat content and body protein content of the adult insect which all of these parameters (body weight, body lipid content and body protein content) have important effect on the insect diapauses and the insect reproduction
