Abstract

Florida is the second-highest producer of strawberries in the USA. Chilli thrips Scirtothrips dorsalis Hood (Thysanoptera: Thripidae) have become a major pest in Florida strawberries following its establishment in the USA after 2005. Insecticide application is the leading management approach for S. dorsalis. However, this pest demonstrated the tendency to develop resistance to a broad range of active ingredients. Host-plant resistance (HPR) may contribute to the management of this pest, yet mechanisms of HPR, including antixenosis and antibiosis against S. dorsalis in strawberries, are not well studied. Therefore, this study aimed to evaluate the preference of S. dorsalis to select strawberry cultivars as oviposition sites that resulted in a successful egg eclosion. Seven commercial strawberry cultivars namely, "Florida Brilliance," Florida Medallion "FL 16.30-128," Sweet Sensation "Florida 127," Florida Pearl "FL 16.78-109," "Strawberry Festival," "Florida Beauty," and "Florida Radiance" were evaluated as hosts in an oviposition choice test. Greenhouse potted strawberry plants were infested with 1- to 3-d-old adult S. dorsalis females. The cultivars used as treatment were replicated five times, and the study was repeated twice. Among the seven cultivars, Florida Pearl "FL 16.78-109," "Florida Beauty," and "Strawberry Festival" had a higher number of eggs in the leaf tissue compared with other tested cultivars. However, the egg hatching percentage did not demonstrate a specific trend. The results showed that S. dorsalis has a strong oviposition preference for certain strawberry cultivars over others, and this information may be incorporated into HPR for managing S. dorsalis in strawberries.

草莓品种辣椒蓟马产卵行为的比较研究。

佛罗里达州是美国第二大草莓产地。辣椒蓟马（thirtothrips dorsalis Hood）（蓟翅目：蓟科）自2005年在美国佛罗里达州出现以来，已成为草莓的主要害虫。施用杀虫剂是主要的管理方法。然而，这种害虫表现出对多种有效成分产生抗性的趋势。寄主-植株抗性（HPR）可能有助于管理这种害虫，但HPR的机制，包括抗异种性和对草莓桃蚜的抗生素，尚未得到很好的研究。因此，本研究的目的是评价桔粉蛾选择草莓品种作为产卵地点的偏好，从而使卵成功羽化。以“Florida Brilliance”、“Florida Medallion”FL 16.30-128、“Sweet Sensation”Florida 127、“Florida Pearl”FL 16.78-109、“strawberry Festival”、“Florida Beauty”和“Florida Radiance”7个商品草莓品种作为宿主进行产卵选择试验。温室盆栽草莓以1 ~ 3龄成年背蚜雌虫为主。处理品种重复5次，重复2次。7个品种中，“佛罗里达珍珠”“FL 16.78-109”、“佛罗里达美人”和“草莓节”的叶片组织卵数高于其他品种。然而，鸡蛋孵化率没有表现出特定的趋势。结果表明，桃蚜对某些草莓品种具有较强的产卵偏好，这一信息可用于草莓桃蚜的HPR管理。
