Revision of Indo-Pakistan Parisomias Faust (Coleoptera,Curculionidae) with some notes on Leptomias Faust

Summary

Mandibles and maxillae of Australonuphis teres (family Onuphidae) continue to grow throughout life without replacement. Mandibles are solid structures that grow by external depositions, leaving a series of growth rings. Maxillae are hollow without any growth rings. New teeth are added to a maxilla by the division of its most distal tooth. Overall growth of the maxillae is thought to occur from the inner epidermal layer of the cavity. The same mode of growth is expected in all extant Eunicoidea with exception of Dorvilleidae, where maxillae are periodically replaced.     

苹果园地面植被的优化组合对害螨和天敌群落组成的影响

苹果园种植紫花苜蓿,为捕食性天敌提供了适宜的生存环境和补充猎物,使苹果园天敌数量增加,叶螨种群下降,夏至草是苹果园杂草的优势种,该杂草可为果园前期提供天敌生存所需的花粉,花密和猎物,使东亚小花蝽发生时间早,发育速度快,将有益杂草夏至草引入果园和紫花苜蓿搭配,可弥补单纯紫花苜蓿对天敌早期增殖的不足,夏至草与紫花 苜蓿的比例变化,影响苹果园节肢动物物种数量,当夏至草的覆度大于25％时,对地面植被和苹果树冠捕食于敌种群数量最为有利。     

The flower bug genus Orius Wolff, 1811 (Hemiptera: Heteroptera: Anthocoridae: Oriini) of Thailand

The flower bug genus Orius Wolff, 1811 (Hemiptera: Heteroptera: Anthocoridae: Oriini) in Thailand is reviewed. Eleven valid species are recognised; seven of them are described as new to science: Orius (O.) sakaerat, O. (O.) taksini, O. (O.) tomokunii, O. (O.) filiferus, O. (O.) machaerus, O. (O.) inthanonus and O. (Trichorius) crassus. Orius (Heterorius) dravidiensis Muraleedharan, 1977, which has been known from India, is recorded from Thailand for the first time, and is correctly placed in the subgenus Dimorphella Reuter, 1884. The subgenus Paraorius Yasunaga and Miyamoto, 1993 is proposed as a synonym of Dimorphella. Diagnoses, digital habitus images, scanning electron micrographs and illustrations of diagnostic features including both male and female genitalia are provided. Keys to the Thai species are offered to facilitate identification. Biology of Thai species is also discussed.
