The webbing life type of three spider mite species of the genus Oligonychus was studied based on web-associated behavioral characteristics. All tested Oligonychus species—viz., avocado brown mite, Oligonychus punicae (Hirst), date palm mite, Oligonychus afrasiaticus (McGregor), and banks grass mite, Oligonychus pratensis (Banks)—exhibited a complicated-web (CW) life type on various host plants. A new life type, ‘CW-c,’ was documented for O. punicae on the adaxial leaf side of Conocarpus erectus L. (Combretaceae). The weaving pattern with guy ropes is spun by the O. punicae female and is associated with stalked eggs; it appeared as a unique character in the CW-life type. Oligonychus afrasiaticus, also showed a new life type, ‘CW-d,’ when reared on the abaxial side of leaves of four host plants, viz., desert fan palm, maize, sorghum, and sugarcane. Oligonychus afrasiaticus showed a site for quiescence and a site for oviposition as variables, whereas the site for defecation (SD) was a persistent characteristic on all four tested host plants. Oligonychus pratensis showed the characteristics of the sub-type ‘CW-u’ on the abaxial leaf side of Washingtonia filifera (Lindl.) H. Wendl. (Arecaceae). The SD was a distinguishing behavioral characteristic used to separate O. afrasiaticus from O. pratensis when inhabiting the same host plant, W. filifera.

两种新生命类型和对某些寄主植物在寄主植物上与网相关的行为特征的评估

属的三个红蜘蛛种织带寿命型Oligonychus基于Web相关的行为特征进行了研究。所有测试Oligonychus物种即,鳄梨褐色螨,Oligonychus punicae(赫斯特),海枣螨,Oligonychus afrasiaticus(麦格雷戈),和银行草螨,Oligonychus禾(银行)-exhibited一个复杂的Web(CW)生活型上各种寄主植物。记录了一种新的生活类型“ CW-c”,它是指直立Conocarpus erectus L.(Combretaceae)的近侧叶上的O. punicaeO. punicae用带子的绳索编织图案雌性,伴有茎鸡蛋;它在CW-life类型中表现为独特角色。当在四个寄主植物的叶子的背面,即沙漠扇形棕榈,玉米,高粱和甘蔗的背面培育时,Oligonychus afrasiaticus也显示出一种新的生命类型“ CW-d” 。Oligonychus afrasiaticus显示出一个静止的位点和一个产卵的位点作为变量,而排便(SD)的位点是所有四种测试寄主植物的持久特征。短木(Oligonychus pratensis)在Washingtonia filifera(Lindl。)H. Wendl的背面叶侧表现出亚型“ CW-u”的特征。(木犀科)。SD是用于区分O. afrasiaticus的独特行为特征当居住在同一寄主植物W. filifera中时,来自O. pratensis
