Abstract

ABSTRACT: Mirid bugs (Hemiptera: Miridae) are important pests of Eucalyptus (Myrtaceae) trees in Indonesia. Young Eucalyptus plantations are mainly affected by Helopeltis spp. Damage by Helopeltis resulted in die-back of young shoots, curling, deformation and drying usually, irrespective of the clones. In North Sumatra, damage in Eucalyptus is associated to Helopeltis bradyi Waterhouse despite the presence of H. theivora Waterhouse in the region. Important alternate host plants recorded as reservoirs of H. bradyi in vicinity to Eucalyptus plantations were Persea sp. (Lauraceae), Coffea sp. (Rubiaceae), Psidium guajava (Myrtaceae), Ludwigia sp. (Onagraceae), Clidemia hirta (Melastomataceae) and Theobroma cacao (Malvaceae). Leiophron sp. (Hymenoptera: Braconidae) was reported as an important parasitoid with parasitism of 41.86% on the H. bradyi nymphs and 17.07% on adults. Helopeltis theivora was recorded as the only species affecting Eucalyptus plantations in Riau Province, so far no other Helopeltis sp. has been identified in Riau. Ragwelellus festivus Miller and Ragwelellus sp. were reported for the first time damaging Eucalyptus trees in North Sumatra, Riau Province and East Kalimantan regions of Indonesia. Arthriticus eugeniae Bergroth was also reported for the first time damaging matured Eucalyptus trees along with Ragwelellus in North Sumatra and Riau Provinces.
印尼桉树Mirid害虫:危害症状、替代寄主和寄生虫的注意事项
摘要:盲蝽(半翅目:盲蝽科)是印度尼西亚桉树的重要害虫。幼桉树人工林主要受赤杨病的影响,不论无性系,赤杨病的危害主要表现为幼芽枯死、卷曲、变形和干燥。在北苏门答腊,桉树的损害与布氏Helopeltis bradyi Waterhouse有关,尽管该地区存在H. theivora Waterhouse。在桉树人工林附近作为布氏夜蛾寄主的主要寄主植物有柏属(月桂科)、咖啡属(茜草科)、瓜爪牙Psidium guajava(桃金娘科)、Ludwigia sp.(龙葵科)、Clidemia hirta(漆树科)和可可可可(锦葵科)。据报道,扁茧蜂(Leiophron sp.,膜翅目:小蜂科)是一种重要的寄生蜂,其寄生率分别为41.86%和17.07%。在廖内省的桉树人工林中,仅记录到Helopeltis theivora,迄今未发现其他Helopeltis sp.。在印度尼西亚北苏门答腊、廖内省和东加里曼丹地区首次报道了Ragwelellus festivus Miller和Ragwelellus sp.对桉树的危害。在北苏门答腊省和廖内省,还首次报道了eugenae Bergroth与Ragwelellus一起危害成熟桉树。
