Three new species of Nilothauma Kieffer are described and figured from Oriental China: Nilothauma angustum sp. n. based on the male only, Nilothauma aristatum sp. n. based on the male, pupa and larva, and Nilothauma bilobatum sp. n. based on the male and pupa. In addition, new distribution records are given for Nilothauma japonicum Niitsuma, Nilothauma nojirimaculatum Sasa, Nilothauma hibarater...

Details of the life cycle of Aneugmenus merida Smith (Hymenoptera: Tenthredinidae) reared under laboratory conditions are reported. Females may produce parthenogenetic or non-parthenogenetic eggs. After eclosion, males of A. merida go through five larval instars, pre-pupa, pupa and imago. The complete life cycle lasts approximately 44 days. Larvae feed on bracken [Pteridium caudatum (L.) and Pt...

Spectral analysis has a very high sensitivity and accuracy, widely used in qualitative and quantitative analysis of textile fibers. This paper described the mechanism of spectroscopy in qualitative identification of textile fibers. Then it gave a systematic review and summary on the research of qualitative or quantitative analysis of textile fibers. It discussed the mechanism of spectroscopy in...

The structure-activity relationship of eclosion hormone from the silkworm, Bombyx mori, was analyzed. First, the probable active residues in silkworm eclosion hormone and also tobacco hornworm eclosion hormone were predicted by the average distance map method. To examine the contributions of those residues to the activity of silkworm eclosion hormone, Gly-substituted mutants for those predicted...

The studies were conducted on the biological aspects of Cyclocephala tucumana Brethes, 1904 and C. melanocephala (Fabricius, 1775) in Aquidauana, MS, Brazil. From January to December 2009 a light trap was installed to make collections of adults of C. tucumana and from January 2010 to February 2011 for collections of adults of C. melanocephala, at the experimental farm of the Universidade Estadu...

Anopheles (Anopheles) mediopunctatus (Lutz) and Anopheles (Anopheles) costai Fonseca & Ramos are redescribed with illustrations of the male genitalia and larval and pupal stages. The pupa of An. costai has paired lateral projections on the wing case, a feature also known in members of the Umbrosus Group from Southeast Asia. An. costai is resurrected from the synonymy of An. mediopunctatus based...

The first North American record for Elachertus scutellatus , a parasitoid of Calpodes ethlius Stoll, occurred August 1999, in Florida. A simple rearing protocol was established to allow the morphology and development of this wasp to be examined. The egg and larval morphology and development of E. scutellatus resemble other Elachertus species. The freshlyecdysed pupa, on the other hand, is rare ...

Sexually dimorphic neural circuits are essential for reproductive behaviour. The molecular basis of sexual dimorphism in the silkworm moth (Bombyx mori) brain, however, is unclear. We conducted cDNA subtraction screening and identified nervous wreck (Bmnwk), a synaptic growth regulatory gene, whose expression is higher in the male brain than in the female brain of the silkworm. Bmnwk was prefer...
