西花蓟马Frankliniellaocumentalis（Pergande）是一种重要的草莓害虫，直接取食草莓的花和果实，严重影响草莓的产量。抑制剂是防治的主要方法，而F.该虫对所有主要化学类别的杀虫剂都产生了抗药性。化学防治不是一项长期战略，需要进行综合虫害管理。本研究确定了F.在3个商品草莓品种中，寄主植物的抗性或耐受性都能减轻草莓晚疫病的危害。测定对赤霉病的抗性或耐受性。根据嗅觉反应、取食损害、产卵偏好和寄主在叶片上繁殖的适宜性，F. octagentalis成年人更喜欢吃Camarosa，然而，如果叶子已经喂过以前的同种，有没有不同的取食偏好。Camarosa是产卵的首选品种，并且产卵量较高。比阿尔比恩和卡米诺真实的都要多。更多的幼虫孵化和成年人饲养从卡马罗萨比无论是阿尔比恩或卡米诺真实的。未孵化的卵、幼虫和蛹的死亡率在卡米诺真实的最高。Camarosa上的存活率最高。卵孵化、预化蛹、化蛹和总发育历期在Camarosa上最短，但幼虫历期在Camarosa上最长。Camarosa是F.叶上的种群增长
ABSTRACT Western flower thrips, Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae), is a major pest of strawberry, causing substantial yield loss through direct feeding on the flowers and fruit. Insecticides are the main method used for its control; however, F. occidentalis has developed resistance to insecticides from all major chemical classes. Chemical control is not a long-term strategy and integrated pest management is required. This study determined whether F. occidentalis damage could be reduced by host plant resistance or tolerance in three commercial strawberry cultivars (Fragaria × ananassa [Rosaceae]: ‘Albion’, ‘Camarosa’, and ‘Camino Real’). Determination of resistance or tolerance to F. occidentalis was based on olfactory response, feeding damage, ovipositional preference, and host suitability for reproduction on leaves. F. occidentalis adults preferred to feed on Camarosa; however, if leaves had been fed on previously by conspecifics, there was no difference in feeding preference. Camarosa was the most preferred cultivar for oviposition, and more eggs were laid by F. occidentalis on Camarosa than either Albion or Camino Real. More larvae hatched and adults were reared from Camarosa than either Albion or Camino Real. The percentage of unhatched eggs, larvae, and pupae that died was highest on Camino Real. Survival rate was highest on Camarosa. Egg incubation, prepupation, pupation, and total developmental periods were shortest on Camarosa, but the larval period was longest on Camarosa. Camarosa was the most favorable cultivar for F. occidentalis population growth on leaves.
