Inhibitory effects of short-term high-temperature pulse on Aphis and the application in its control
China Plant Protection 31 (7), 10-13
Abstract: By simulating fluctuating temperature in greenhouse, the inhibitory effects at different high-temperature pulses (maximum temperature= 33, 35 and 37°C)and ages (1, 2, 3, 4 and 5 day-age) on reproduction and adult life span of Aphis gossypii Glover on cucumber were investigated. The life-time fecundity and life span of adults decreased significantly under the high-temperature pulse at 37°C than those at 33 and 35°C.Compared with younger nymphs at 1-4 day-age, fecundity and life span of adults treated by high-temperature in elder nymph period at 5 day-age decreased evidently. Lethal effects of short term high temperature on A. gossypii at different ages (1, 2, 3, 4 and 5 day-old) were tested at 43 and 45°C for 1, 2, 3, 4, 5 and 6 hours respectively. Results indicated that survival rate of the aphids was lower than 70% after exposure at 45°C for 2 hours. And the possibility of controlling A. gossypii by using high-temperature for a few hours generated by solar radiation in air-tight greenhouses is discussed.
