香蕉冠网蝽Stephanitis(Stephanitis)typica(Distant)又称香蕉网蝽、香蕉花网蝽,属半翅目,网蝽科(Tingidae),是芭蕉科(Musaceae)植物的重要害虫。成虫和若虫群栖于蕉叶背面吸食,破坏蕉叶的叶绿体,被害叶片呈许多浓密的褐黑色小斑点,叶片正面呈花白色斑,影响光合作用,叶片早衰枯死影响香蕉、芭蕉的产量和品质。老蕉园受害率尤其严重。 一、形态特征 1.成虫(图1:1)体长2.1—2.4毫米,刚羽化银白色,渐成灰白色。头小,棕褐色,复眼大而突出,黑褐色。触角4节,第3节细长,约为全长的1/2,末节稍膨大,棕褐色。喙4节,
Stephanitis (Stephanitis) typica (Distant) Also known as banana bug, banana bug, Hemiptera, Tingidae, is an important pest of Musaceae plant. Adults and nymphs inhabit the back of banana leaf to inhale and destroy the chloroplast of the banana leaf. The victim leaves showed many dense spots of brownish black and small spots, and the front of the leaf was white-spotted, affecting photosynthesis. The premature leaf withered death affected the yield and quality of banana and banana . Old banana damage rate is particularly serious. First, the morphological characteristics 1 adult (Figure 1: 1) body length 2.1-2.4 mm, just feather silver white, gradually became gray white. Small head, tan, large and prominent compound eyes, dark brown. Tentacles 4, 3 slender, about the full length of the 1/2, the distal section slightly swollen, brown. 4 beaks,
