| Summary: | (88%) than for sorghum midges that overwintered in shredded 3 May. Among treatments there were no significant 80,408 per ha, emerged between 1 1 April and 19 June 1995 added) soil moisture treatments. Peak emergence occurred on and disked sorghum residue in a field (0.87%). Percent and subsequent severity of damage the insect causes later in bottom thirds of panicies. Percent overwintering survival of differences (F = 0.22, P = 0.81) in the number of sorghum estimated to have entered diapause per square meter of soil from nonsheltered, sheltered (no water), sheltered (water from panicies placed in a field in late winter. included. An average of 170 sorghum midges, equivalent to intermediate to the others. Percent overwintering survival midge, Stenodiplosis sorghicola (Coquillett), that initiate midges to emerge from overwintering diapause because efforts of sorghum midges (mean of 2.1) in the top, middle, and on rate of survival of overwintering sorghum midges in overwintering survival was 6% for sorghum midges to emerge Prediction models of sorghum midge overwintering emergence rainfall event of >-1.27 cm, a greater than normal amount of relation to crop residue destruction treatments were residue shredded and disked, 0.87%, than from residue shredded, disked, and deep-plowed treatment, 0.39%. Percent sorghum midges emerged, The number of sorghum midge larvae sorghum midges was more than twice as high from sorghum survival in the shredded only treatment, 0.56%, was the first spring generation dictate the seasonal abundance the growing season to sorghum, Sorghum bicolor (L.) Moench. Time of emergence from overwintering and abundance of sorghum to keep dry the soil under the sheltered treatments failed was 1,324. There were no significant differences in numbers was x 1 00-fold greater for sorghum midges in a greenhouse when rainfall totals > 1.27 cm. However, @9-12 d following a would be more accurate if effects of moisture and information |
