Two new species of Gelechiidae, Teleiopsis motleella, sp. nov., and Sitotroga pseudopsacasta, sp. nov., are described from Korea. Illustrations of adults and male genitalia are provided. Scrobipalpa spumata (Povolný, 2001), comb. n., is newly recorded from Korea. It was described from the female, and the male genitalia are described and illustrated for the first time.

Two new species, Hilara deryae sp. nov. (Hilara clavipes-group) and Hilara hasankoci sp. nov. (Hilara interstinctagroup) are described from northwestern Turkey. The male and female stages are described, compared with related species and male genitalia and forelegs illustrated. Keys to the western Palaearctic species of Hilara clavipes-group and the Mediterranean species of Hilara interstincta-g...

Ten species of Gynnidomorpha Turner, 1916 occur in China. Gynnidomorpha curviphalla, sp. nov., is described, and G datetis (Diakonoff, 1984) is recorded from China for the first time. Images of adults and genitalia are provided, along with a key to all known Chinese species based on the male genitalia. A map showing the geographic distribution of the species is also provided.

The Drosophila melanogaster Gld gene has multiple and diverse developmental and physiological functions. We report herein that interactions among proximal promoter elements and a cluster of intronically located enhancers and silencers specify the complex regulation of Gld that underlies its diverse functions. Gld expression in nonreproductive tissues is largely determined by proximal promoter e...

Effect of oral administration (50, 100, and 200 mg/kg body weight/day, for 28 days) of aqucous leaf extract of neem (Azadirachta indica) on the male reproductive organs of the Parkes (P) strain mice was investigated. The treatment had no effect on body weight and the reproductive organs weight. In treated mice, testes showed both normal and affected seminiferous tubules in the same sections; th...

The formation of reproductive organs is a defining characteristic of sexual reproduction in flowering plants. Unlike animals, plants do not establish a germline early in development. In flowering species, specific somatic cells present in sexual reproductive organs divide by meiosis and differentiate haploid precursors (named spores) that undergo several mitotic divisions before giving rise to ...

Guanylyl cyclase B is the receptor for a small peptide (C-type natriuretic peptide) produced locally in many different tissues. To unravel the functions of the receptor, we generated mice lacking guanylyl cyclase B through gene targeting. Expression of the receptor mRNA in tissues such as bone and female reproductive organs was evident, and significant phenotypes associated with each of these t...

The confinement of male rats in complete dankness from birth until 47 days of age resulted in severe retardation of reproductive function. The supply of light-on condition for the last one week caused a remarkable overshoot of testosterone secretion beyond the level of intact animals, associating with a significant weight increase in accessory reproductive organs. Eye-enucleation nullified thes...
