中国羽毒蛾属记述(鳞翅目:毒蛾科)

羽毒蛾属(Pida Walker,1865)隶于毒蛾科。模式种羽毒蛾(Pida apicalis Walker,1865)。本属下唇须向上,过头顶,下唇须、前足和胸部均被长毛,后足胫节有二对距;前翅径室大,R_1脉起于中室前缘,R_2脉起于径室前缘,接近径室顶角,R_3脉、R_4脉与R_5脉共柄,起于径室顶角,但R_5脉距离中室很近,M_1脉起于中室上角,M_2脉接近中室下角分     

雪毒蛾和杨雪毒蛾的鉴别

<正> 雪毒蛾Stilpnotia salicis(Linnaeus)和杨雪毒蛾Stilpnotia candida Staudinger隶属于鳞翅目(Lepidoptera)毒蛾科(Lymantriidae),此两种害虫在我国分布广泛,是我国防护林、园林、行道树上的重要害虫。由于成虫在外部形态上十分相似,都是足带黑斑的白色毒蛾,而幼虫均为害杨属(Populus)和柳属(Salix)植物,所以过去容易将完全不同的两个种误认为是一个种,称为柳毒蛾。在实际害虫防治中,由于不能正确识别种类,将两种混为一谈,往往防治效果     

毒蛾科昆虫卵块上覆盖的“毛”仍是雌蛾腹端的体毛

《昆虫知识》1977年第14卷第4期刊登贵州湄潭茶叶科学研究所植保组的《茶毛虫卵块上的“毛”从何而来?》一文。他们通过对茶毛虫Euproctis pseudo con-spersa Strand黄毒蛾 Arcaxa flava Bremer和黄尾毒蛾 Euproctis similis Fuessly三种毒蛾科的雌蛾腹部进行了解剖,提出了这三种毒蛾卵块上的毛是由体内腹囊的排泄物遇空气后所形成的,从而对以往书刊上记载的毒蛾科卵块上覆盖的是雌蛾腹端毛丛脱落的说法认为是错误的。此文发表以来,还未见有人提出异议。

Two New Species of Afronurus (Ephemeroptera: Heptageniidae) from Vietnam

ABSTRACT Two new species of the heptageniid mayfly genus Afronurus Lestage, Afronurus meo sp. n. and Afronurus mnong sp. n., are described from Vietnam with line-drawings of key characters. The larvae of A. meo can be characterized by rowed minute spines in the posterior margin of the abdominal terga 1-9 and distinct markings on anterior head, dorsal femora, and abdominal terga. The larvae of A. mnong can be characterized by scattered simple stout setae on the anterior margin and dorsal surface of femora, rowed acute spines on the posterior margin of abdominal terga 1-9, and plain brown body color. Their diagnoses, material data, distributions, and habitat and biological data are provided.     

Discovery of swimming larvae in Elmidae (Coleoptera: Byrrhoidea)

The aquatic larvae of the family Elmidae (Coleoptera) have been considered unable to swim because they lack swimming setae on their body and legs. We discovered that riffle beetle larvae (Leptelmis gracilis Sharp) are in fact able to swim. After opening the tuft‐like gills on the last abdominal segment they swim by repeatedly bending the abdomen into a U‐shape very quickly and in a wavy manner, while their head and thorax move anteriorly, resulting in a sigmoidal body shape. The flat bodies of L. gracilis larvae could be advantageous for swimming compared to the cylindrical or semicylindrical bodies of larvae in related genera.     

Midges of the subfamily Tanypodinae (Diptera,Chironomidae) of Russia: Tribes Coelotanypodini Kieffer, 1913 and Tanypodini Meigen, 1803

It is established that in the territory of Russia the subfamily Tanypodinae (Diptera, Chironomidae) includes 80 species belonging to 10 subgenera of 8 genera and 5 tribes; 4 species are recorded for the first time in the Palaearctic Region, and 16 species, in Russia. In the present study, larvae, pupae, and male adults from different areas of Russia, belonging to 9 species of 2 subgenera, 2 genera, and 2 tribes, are examined. Keys to larvae, pupae, and male adults of these species is provided.     

A new species of Acentrella Bengtsson (Ephemeroptera: Baetidae) from Great Smoky Mountains National Park,USA

Acentrella barbarae sp. n. is described from eggs, larvae, and imagines collected from Great Smoky Mountains National Park, North Carolina and Tennessee, USA. Larvae were collected from cobble-pebble substrate in stream rapids. Life stages were associated by rearing. Eggs have longitudinal chorionic ridges with small, longitudinal furrows. Larvae are distinguished by having segment 3 of the labial palp apically rounded, abdominal terga with posteromedian projections, and tibiae and tarsi with relatively short setae on the outer margins. Imagines are distinguished by the colouration and posterior elevation of abdominal terga. Other Acentrella larvae occur in the same streams as the new species, including A. parvula, which we report from Tennessee for the first time. We provide an updated key to the larvae of North American Acentrella species.     

Larval morphology of the scorpionfly Dicerapanorpa magna (Chou) (Mecoptera: Panorpidae) and its adaptive significance

Larval morphology can provide valuable characters for taxonomic and phylogenetic analyses of insects and reflect the adaptations to various living habits. Compared with the adult stages, larval study has lagged far behind in Mecoptera. Although several genera of Panorpidae have been studied for their larval stages, the larva of Dicerapanorpa Zhong and Hua, 2013 basically remains unclear. Here the larva of Dicerapanorpa magna (Chou) is described and illustrated in detail for the first time using light microscopy and scanning electron microscopy. The larva is eruciform, with eight pairs of abdominal prolegs in addition to three pairs of thoracic legs, as in other Panorpidae. The most remarkable characteristics of the larvae include a pair of erect subdorsal annulated processes each on abdominal segments I–IX (A1–A9) and a single middorsal annulated process on A10, as well as a pair of prominent compound eyes composed of over 40 ommatidia, which distinguish this genus from other genera of Panorpidae. The annulated processes may have adaptive significance for fossorial and soil-living habits.

A new record of monogeneric family Vietnamellidae (Insecta: Ephemeroptera) from India

A new record of monogeneric family Vietnamellidae (Insecta: Ephemeroptera) is established for India with Vietnamella sp. A described based on the larvae from Arunachal Pradesh, India. This species can be distinguished from other known species of this genus in the larval stage by the following combination of characters: (i) outer pair of projections in head large and stout, triangular, cone-shaped with serrated spines; (ii) posterolateral angles of abdominal terga 2–9 extended into sharp projections; (iii) caudal filaments pale yellowish brown with dense lateral setae on inner and outer margins of middle part; (iv) femora of mid- and hind-legs broader; and (v) second segment of the maxillary palpi shorter than first segment.
