- Abstract:
- The growth and development of Clavigralla tomentosicollis Stäl (Hemiptera : Coreidae) and Maruca testulalis Geyer (Lepidoptera : Pyralidae) were studied under laboratory conditions using three cultivated Vigna varieties (IT84E-124, TVu 1890, MRx 10-85S) and one wild variety (TVNu 72) under a range of temperatures : 19°C, 22°C, 25°C, 28°C, 31°C, 34°C, 37°C, 40°C and 43°C. IT84E-124 served as the susceptible and TVNu 72 as the resistant control for both insects. Development time of C. tomentosicollis ranged between 7 days at 37°C to 26 days at 19°C, and decreased with increasing temperature up to an upper temperature threshold of 37°C(.).
