| Abstract: | The susceptibility of 5 soyabean cultivars in 4 maturity groups to damage by stink bugs, primarily Nezara viridula (L.), Acrosternum hilare (Say) and Euschistus spp., was evaluated in field-plot tests in South Carolina in 1974-75. The cultivar Essex matured early and escaped some of the severe damage caused by the larger bug populations later in the season. In 1975, a new method of assessing the severity of stink-bug damage was used to compare the susceptibility between early and late sowings (made on 22 May and 24 June, respectively) of 6 cultivars and one insect-resistant breeding line. Damage was more severe among early sowings, seed-weight loss averaging 22.9% compared to 16.0% for late sowings. Among the late-sown cultivars, Cobb and ED73-371 incurred significantly less seed-weight loss (11.4%) than Bragg (23.9%). Differences in damage were not directly related to differences in the length of the pod-development stages in each case. |
