Abstract
Laboratory and field experiments revealed the importance of relative humidity (RH) and panicle-wetting (artificial or rainfall) on emergence of adult sorghum midge, Contarinia sorghicola (Coquillell), from sorghum spikelets. In the laboratory, more midges emerged from spikelets maintained at high relative humidity (RH) (90%) than at 10% RH and 50% RH. In field trials, male emergence occurred at higher RH, lower temperature, and earlier in the day than female emergence. Artificially wetting panicles for 3 h or a heavy rainfall resulted in reduced adult emergence. Increased adult emergence occurred during periods of high RH before and after heavy rainfall.
