| Abstract | ||
| Legumes such as chickpea and lentil play an important role as rich food for many people since it constitutes 20-30% protein and 58% carbohydrate. The susceptibility of four chickpea and three lentil varieties to Callosobruchus maculatus (F.) infestations were evaluated in the laboratory at 28±1°C, and 65-75% R.H. Many insect biological parameters were studied as eggs number, mean developmental period (MDP), adult progeny, susceptibility index (SI), seed damage percentage, weight loss percentage and germination percentage. Chickpea and lentil varieties showed non-significant differences for MDP and SI to insect infestation. All chickpea seed varieties were susceptible more than lentil seed varieties. Giza 1 variety was the least susceptible in chickpea varieties while Giza 29 was least susceptible one in lentil varieties. Our results showed that insect infestation for chickpea varieties were more than lentil seed varieties infestation. Chemical analysis of the main seed components of the tested different varieties suggest that the susceptibility of these varieties to C. maculatus infestation may be attributed to the high content of carbohydrate and low content of crude fiber in chickpea varieties more than lentil varieties compared to resistance varieties. | ||
