Abstract

A study was conducted on citrus and avocado trees in north-western Morocco between February 2023 and April 2024 to detect scale insects (Hemiptera: Coccomorpha) and their associated natural enemies. A total of 55 orchards in seven provinces were studied. The Florida red scale, Chrysomphalus aonidum (Linnaeus, 1758) (Diaspididae) was found on leaves at two sites: a moderate infestation in one citrus orchard and one specimen on an avocado tree. This work is the first record of the scale insect on avocado in Morocco, and the first morphological description of C. aonidum from the country, based on 100 adult females mounted on microscope slides. Chrysomphalus aonidum is not causing economic damage in citrus or avocado orchards in Morocco. Two ectoparasitoid wasps (Aphytis melinus DeBach and Aphytis sp.; Hymenoptera: Aphelinidae), and three predatory beetles (Rhyzobius lophanthae Blaisdell, Chilocorus bipustulatus Linnaeus, and Clitostethus arcuatus Rosso; Coleoptera: Coccinellidae), were found associated with C. aonidum on citrus leaves.

摩洛哥柑橘园和一棵鳄梨树上的佛罗里达红鳞Chrysomphalus aonidum (Linnaeus, 1758) (Hemiptera: Diaspididae)

2023 年 2 月至 2024 年 4 月期间，对摩洛哥西北部的柑橘树和鳄梨树进行了一项研究，以检测鳞翅目昆虫（半翅目：Coccomorpha）及其相关天敌。共对 7 个省的 55 个果园进行了研究。在两个地点的叶片上发现了佛罗里达红鳞片虫 Chrysomphalus aonidum (Linnaeus, 1758) (Diaspididae)：一个柑橘园有中度虫害，一个鳄梨树上有一个标本。这是摩洛哥首次记录牛油果上的鳞翅目昆虫，也是摩洛哥首次对 C. aonidum 进行形态学描述，其依据是装在显微镜载玻片上的 100 只雌成虫。Chrysomphalus aonidum 不会对摩洛哥的柑橘或鳄梨果园造成经济损失。在柑橘叶片上发现了两种外寄生蜂（Aphytis melinus DeBach 和 Aphytis sp.；膜翅目：Aphelinidae）和三种捕食甲虫（Rhyzobius lophanthae Blaisdell、Chilocorus bipustulatus Linnaeus 和 Clitostethus arcuatus Rosso；鞘翅目：Coccinellidae）与 Chrysomphalus aonidum 相关。
