橄榄星室木虱属同翅目、木虱科、星室木虱属,是橄榄上最重要的害虫,其成虫、若虫为害刚抽发新梢嫩枝,导致枝叶枯萎,引起落叶、落果,树势严重衰退,产量降低,甚至整株枯死,造成很大损失。 据调查观察,橄榄星室木虱在福州地区可发生7—9代,世代重叠严重,在老树上为7代型,幼树苗上为8—9代型。以成虫、若虫在嫩梢、叶芽、叶片上为害,成虫平时多分散在叶背或新梢上栖息,吸食汁液;若虫聚集在嫩梢、叶芽上吸食,抑制新梢生长。幼叶被害处形成下陷的伪虫瘿,叶面失绿、变小、变薄并稍有皱缩,严重的嫩梢枯死,叶片畸形、扭曲和枯
Olive Starfly Gennomis Homoptera, pygmyidae, Stargardia genus, is the most important olive pests, its adult, nymphs just fresh shoot shoots shoot, resulting in withered branches and leaves, causing deciduous, deciduous, Severe recession, reduced production, and even the entire plant died, resulting in great losses. According to the survey, Olivarius psylla can occur in Fuzhou area 7-9 generations, generations overlap seriously, in the old tree for the 7 generation, young saplings for the 8-9 generation. In adults, nymphs in young shoots, leaf buds, leaves on the damage, the adults usually more scattered in the leaf back or shoot on the habitat, eating juice; nymphs gathered in the tender shoots, leaf buds on the absorption, inhibition of shoot growth. Young leaf damage at the formation of subsidence pseudocapsules, green leaves, smaller, thinner and slightly shriveled, severe shoots dead, leaf deformity, distortion and dry
