Effect of temperature on development of pink stem borer, Sesamia cretica Lederer, was studied at eight constant temperatures (15, 18, 20.5, 24, 27, 30, 34, and 38°C), a photoperiod of 16:8 (L:D) h, and 50-60% rela\tive humidity. The larvae of pink stem borer were reared on cutting stems of maize. The results showed that temperature had statistically significant effect on developmental times of ...

The sugarcane stalk borers, Sesamia spp. (Lepidoptera: Noctuidae) are the most destructive sugarcane insect pests in Iran. The efficiency of Telenomus busseolae Gahan (Hymenoptera: Scelionidae) used alone or in combination with silicon fertilization was investigated for controlling the sugarcane stalk borers under field conditions.
