Six new species of other stem flies infesting mostly legumes were also discovered under the genus Melanagromyza (stem flies) from Pantnagar, Northern India. These were: M. species new ex stems of Cassia sp. (proposed name M. pathaki new species); M. species new ex stems of Glycine max (Linn.) Merril. (proposed name M. glycini new species); M. species new ex stems of Medicago denticulata willd. (proposed name M. denticulata Willd. new species); M. species new ex stems of Pisum sativum Linn. (proposed name M. pisiphaga new species); M. species new ex stems of Trifolium pratense Linn,. (proposed name M. sehgali new species) and M. species new ex stems of Vicia faba Linn. (proposed name M. vicivora new species). New names have been proposed to them as per International rules of Zoological Nomenclature. Other stem flies redescribed by author include: Ophiomyia centrosematis de Meijere, Opmiormyia phaseoli (Tryon) and Ophiomyia cicerivora. More than one thousand male genitalia slides were prepared for this study. Variations in morphology and genitalia characters have been described between and within the species. Melanagromyza sojae (Zehtner) has been redescribed here. DOI: http://dx.doi.org/10.3126/njbs.v2i0.7491 Nepalese Journal of Biosciences 2 : 64-70 (2012)

Twelve years ago Priestley and Ewing (1923) reported that in certain plants, normally showing but little development of stem-endodermis, an extensive formation of this layer could be induced by etiolation. (Note: In this paper the term endodermis is used only when the layer shows characteristic structural features—in the present case the Casparian strip.) A later paper by Priestley (1926) dealt with the same subject. The specified plants with which this result was obtained consisted of four closely related species, namely, Vicia Faba, V. sativa*, Pisum sativum, and Lens esculenta*, and also Solanum tuberosum. (The statements relating to the species marked with an asterisk are based on unpublished work carried out at Leeds, kindly placed at the author's disposal by Professor J. H. Priestley.) In these plants a primary endodermis, though present only at the base of the normal shoot, was described as extending to a considerable height in the etiolated shoot. It was concluded that the absence of endodermis from the greater part of the shoot of these plants, when grown under normal conditions, arises from the inoperation, in the presence of light, of the mechanism forming the Casparian strip.

We studied the effectiveness of glyphosate [N-(phosphono-methyl)glycine] for the control ofOrobanchespp. in the field when applied to the crop foliage prior to the emergence of the parasite. The bestOrobanchecontrol in October-sown carrots (Daucus carotaL.) parasitized byOrobanche crenataForsk. andO. aegyptiacaPers. and in December-sown broad bean (Vicia fabaL.) and peas (Pisum sativumL.) parasitized byO. crenatawas obtained by spraying twice, 2 weeks apart, in late January and in February, respectively. Carrot root yield remained unaffected by glyphosate at rates up to 200 g/ha. In heavily infested fields, carrots were irreversibly damaged by earlyOrobancheparasitism. The highest yields of pods of broad beans occurred after two or three applications of 150 g/ha glyphosate. Peas were seriously damaged by 150 g/ha. Two or three sprays of 50 g/ha glyphosate resulted in the highest green-kernel yield of pea where the soil was not heavily infested. Glyphosate effectively reducedO. cernuaLoeffl. emergence in non-irrigated tomatoes (Lycopersicum esculentumMill.), but was very phytotoxic to the crop. Glyphosate was highly effective in controllingOrobanchespp.; however, marginal selectivity may be sufficient in some crops and not in glyphosate-susceptible ones.
