中文摘要 | 土中施用得滅克 (Aldicarb) 可減少棉株上的煙草粉蝨,但對銀葉粉蝨 效果不高。施用得滅克也可減少棉珠早期的薊馬,葉蟬和damsel bugs的為害。 施用得滅克後,棉株發育較未施用者為佳。在棉株生育中期和末期 (1993年6 月21日至7月26日) 銀葉粉蝨密度低時,施用得滅克後粉蝨若蟲數量從每平 方公分葉片8隻減少至4隻,棉花產量增加42%;但在銀葉粉蝨密度高時 (1994 年6月15日至7月27日每平公分葉片18.9隻若蟲),施用得滅克的效果因為粉 蝨的嚴重為害而消失。 |
英文摘要 | Soil application of aldicarb reduced numbers of sweetpotato whitefly (SPW), Bemisia tabaci Gennadius, but not silverleaf whitefly (SLW), B. argentifolii Bellows and Perring , on upland cotton, Gossypium hirsutum L. Aldicarb-treated plants also had significantly fewer thrips, Frankliniella spp., leafhoppers, Empoasca spp., and damsel bugs, Nabis spp. early in the season, than untreated plants. Aldicarb-treated plants exhibited more vigorous plant growth than untreated plants. In mid-to late season from 21 June to 26 July in 1993 when SLW population density was low (8.0 nymphs/cm leaf disk for untreated plants) fewer SLW occurred on aldicarb-treated plants (4.4 nymphs/cm leaf disk). Lint yield increase was 42% as compared to untreated plants. In 1994, when SLW population density was high from mid-to late season from 15 June to 27 July (18.9 nymphs/cm leaf disk for untreated plants) the beneficial effect of aldicarb treatment was negated by the whitefly damage. |
