Abstract

Strawberries are infested with Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae) in Egypt. This study evaluated the effects of the biochemical components and leaf surface characteristics of ten new strawberry cultivars (Fortuna, Festival, Sahary, Forintaris, Red Merlin, Winter Star, Winter Dawn, Eliana, Montary and Florida) on the levels of infestation by F. occidentalis. There were significant differences in the susceptibility of strawberry cultivars to infestation by F. occidentalis. Fortuna, Sahary, Festival and Forntaris were the most susceptible cultivars. Red Merlin, Winter Star, Winter Dawn and Eliana had intermediate infestations. Montary and Florida were the most resistant cultivars. The relationship between mean number of F. occidentalis and leaf nitrogen was not significant. There was a significant relationship between mean numbers of F. occidentalis and phosphorus, potassium and total phenols content of leaves. The highest mean numbers of F. occidentalis were found on leaves of the Fortuna cultivar with high levels of phosphorus and low levels of potassium and total phenol. The lowest mean numbers of F. occidentalis were found on the leaves of the Montary and Florida cultivars with low levels of phosphorus and high levels of total phenols and potassium. Cultivars with higher density of non-glandular trichomes had significantly fewer F. occidentalis than cultivars with lower densities of non-glandular trichomes on the upper leaf surface. Similarly, cultivars with thicker leaves had significantly fewer thrips than cultivars with thinner leaves. The proper choice of strawberry cultivar is an important component of integrated pest management programs for controlling thrips in strawberry nurseries.

苗圃中草莓新基因型对西部花蓟马Frankliniella occidentalis (Pergande)的易感性
在埃及,草莓被西方富兰克林蝇(桔梗)(蓟翅目:蓟科)侵染。本研究评价了10个草莓新品种(Fortuna、Festival、Sahary、Forintaris、Red Merlin、Winter Star、Winter Dawn、Eliana、monont和Florida)的生化成分和叶片表面特征对西花蓟马侵染程度的影响。草莓品种对西花蓟马侵染的敏感性存在显著差异。Fortuna、Sahary、Festival和Forntaris是最敏感的品种。“红梅林”、“冬之星”、“冬之黎明”和“伊莲娜”有中度虫害。蒙特和佛罗里达是抗性最强的品种。西花蓟马的平均数量与叶片氮含量的关系不显著。叶中磷、钾和总酚含量与平均西花菌数呈极显著相关。在磷含量高、钾和总酚含量低的品种叶片上,西褐飞虱的平均数量最高。在磷含量低、总酚和钾含量高的蒙特和佛罗里达品种的叶片上,西叶镰刀菌的平均数量最低。非腺毛密度较高的品种在叶上表面的西叶镰刀菌数量显著少于非腺毛密度较低的品种。同样,叶片较厚的品种的蓟马数量明显少于叶片较薄的品种。草莓品种的合理选择是草莓苗圃蓟马病虫害综合治理方案的重要组成部分。
