ABSTRACT

The effects of temperature (20°C, 25°C, 30°C) and photoperiod (16D:8N, 12D:12N, 8D:16N) on larval body weight, food consumption, egg production, and survival of Gastroidea viridula Deg. (Coleoptera: Chrysomelidae) were determined. Temperatures and photoperiods affected insect development time, larval body weight, and survival. Larvae continued development while 60 days at temperature of 20°C and photoperiod of 8D;16N, but only while 30 days at 30°C, 16D:8N and 12D:12N. Photoperiod not affected the oviposition period and number of eggs produced. Results show that both temperature and photoperiod significantly affects larval body weight and survival.

Key words: Rumex confertus Willd., mossy sorrel, Gastroidea viridula Deg., dock leaf beetle, development, survival, temperature, photoperiod.
