Monoammonium Phosphate Effects on Glyphosate in Soils: Mobilization,Phytotoxicity, and Alteration of the Microbial Community

Eurasian Soil Science - Application of monoammonium phosphate has been demonstrated to re-immobilize glyphosate sorbed by soil under model laboratory experiment conditions. This effect was most...     

Sex attractant of the black carpet beetle

The principal component of the sex attractant of the black carpet beetle Attagenus megatoma (Fabricius) is trans-3, cis-5-tetradecadienoic acid.     

Western pine beetle: field response to its sex pheromone and a synergistic host terpene, myrcene

In the field, both sexes of the western pine beetle, Dendroctonus brevicomis, are attracted by the female-produced bicyclic ketal exo-brevicomin; this response is enhanced by myrcene (a constituent of the beetle's host, ponderosapine), which is not an attractant by itself. This synergism may be part of the phenomenon of the mass attack on its host. Temnochila virescens chlorodia, one of the principal insectan predators of this beetle, is attracted by exo-brevicomin alone.     

Water regime and fertilizer doses for rice crops with periodic watering in the Lower Volga region

This paper considers the results of studies on substantiating the optimal combination of controllable factors of growth and development of rice that provide grain yields of 4 and 5 t/ha under overhead irrigation. We determined the reaction rates of periodically watered rice to a different combination of water and nutrition modes of the soil, which make it possible to reduce the cost of irrigation water for rice cultivation by 2.4–6.9 times compared with the conventional technology and to bring the total water consumption of this culture to being biologically sound.     

Sex Attractant of Female Dermestid Beetle Trogoderma inclusum Le Conte

Two components of the sex attractant of a female dermestid beetle Trogoderma inclusum Le Conte were identified. They are (-)-14-methyl-cis-8-hexadecen-1-ol and (-)-methyl-14-methyl-cis-8-hexadecenoate. Other Trogoderma species also respond to the compounds.
