在一项实验中，欧洲的一种被称为Lygus rugulipennis的植物臭虫被关在正在发育的草莓花或幼小的果实上，这种昆虫导致了果实的畸形。另一种衣壳虫，斜菊，造成类似的损害；本种在英国草莓晚季作物上的数量少于rugulipennis。其他昆虫有时会大量出现在晚季草莓的花朵上，即各种蓟马和花粉甲虫，在笼养实验中不会导致果实变形，尽管蓟马有时会导致果实变色。在田间试验中，施用杀虫剂减少了rugulipennis的数量，与未施用杀虫剂的地块相比，畸形果的数量大大减少。在果实发育早期存在的rugulipennis数量与果实畸形损害评分之间的相关性非常显著。这种衣壳很可能是英国草莓晚季作物果实畸形的主要原因。
In experiments in which the European tarnished plant bug, Lygus rugulipennis, was caged on the developing flowers or young fruits of strawberry, the insects caused malformation of the fruits. Another species of capsid, Plagiognathus chrysanthemi, caused similar damage; this species is less numerous than L. rugulipennis on late‐season crops of strawberry in UK. Other insects which sometimes occur in large numbers in the flowers of late‐season strawberry, i.e. various species of thrips and pollen beetles, did not cause fruit malformation in caging experiments, though thrips sometimes caused discoloration of the fruit. In field experiments where numbers of L. rugulipennis were reduced by the use of insecticides, the amount of misshapen fruit was reduced greatly compared to untreated plots. Correlations between the numbers of L. rugulipennis present at the early stages of fruit development and damage scores for fruit deformity were highly significant. This capsid is likely to be the major cause of fruit malformation in late‐season crops of strawberry in the UK.
