Sulfoxaflor binds to nAChR in place of acetylcholine and acts as an allosteric activator of nAChR. Thanks to its mode of action resistance phenomena are uncommon, even few cases of resistance were reported. It binds to receptors determining uncontrolled nerve impulses followed by muscle tremors to which paralysis and death follows. Sulfoxaflor acts on the same receptors of neonicotinoids as nicotine and butenolides, but it binds differently. It binds to insects nAChRs more strongly than to mammals’ ones, so it is much less toxic for mammals and man. Sulfoxaflor is supposed to have a low environmental impact and is not much aggressive against non-target species. Unfortunately, it is toxic to impollinator insects, so it must be used only in compliance with a series of legislative norms. At present sulfoxaflor can be considered one of the most interesting products to be used in fighting against agriculture insect pests.</p> L. Bacci, S. Convertini, B.

Leaves from these plants were smouldered in order to provide mosquito repellent smoke. Complete knock down was provided 40 minutes after mosquitoes were exposed to smoke of <em>T. erecta</em>, 60 minutes to smoke of <em>T. minuta</em> and <em>E. grandis</em> and 120 minutes to smoke of<em> L. javanica</em>. Complete knock down of mosquitoes could not be provided by <em>L. camara</em> within the 140-minute exposure period. The KT50 (time required to knock down 50% of the mosquitoes) values were 24.985 minutes (<em>T. minuta</em>), 34.473 minutes (<em>T. erecta</em>), 59.119 minutes (<em>L</em>. <em>javanica),</em> 59.828 minutes (<em>L. camara</em>) and 25.245 minutes (<em>E. grandis</em>). The KT90 (time required to knock down 90% of the mosquitoes) values were 48.060 minutes (<em>T</em>. <em>minuta),</em> 50.169 minutes (<em>T</em>. <em>erecta),</em> 178.341 minutes (<em>L</em>. <em>javanica),</em> 140.220 minutes (<em>L. camara</em>) and 47.998 minutes (<em>E</em>. <em>grandis).</em> Mortality rates 24h after exposure were 40% (<em>T. minuta),</em> 100% (<em>T. erecta</em>), 75% (<em>L. javanica</em>), 90% (<em>L. camara</em>) and 100% (<em>E. grandis</em>). In conclusion, smoke from the plants <em>T. erecta, T. minuta</em> and <em>E. grandis</em> had very fast knock down rates with<em> T. erecta,</em> <em>L. camara</em> and <em>E. grandis</em> killing over 90% of the A<em>n. arabiensis</em> mosquitoes. Plant smoke is important in mosquito control.</p> N. Lukwa, T. Mduluza, C. Nyoni, A.T. Lukwa, M.

Different types of insecticides have been used to control subterranean termites. The present studies were conducted to evaluate the comparative persistency and effectiveness of Termiban (imidacloprid 5 SC) and Chlorpyrifos (40 EC) against subterranean termites in the three type of soils (sand, silt and clay) at different time interval. Two different concentrations (100 and 200 ppm) of selected insecticides were prepared and applied to soil in petri plates and termite were released at different time interval to record mortality. Results showed that at each time interval and concentration, mortality of termite was non-significantly different for both insecticides. When persistency of insecticides was tested under closed condition, results showed that lowest weight loss (8.60%) of wood was observed in Termiban treated soil at 200 ppm which was significant different from rest of the treatments. Similarly, under open conditions, at each time interval, there was significant more mortality of termites in soil treated with Termiban compared to Chlorpyrifos.</p> B. Hassan, S.

Outside of Russia, <em>M. holosericea</em> is distributed in Kazakhstan, Mongolia, some northern provinces of China, the Korean peninsula and Japan. Within the Russian Federation, the species is recorded in 30 administrative regions (the Far East, Eastern, Western and Southern Siberia, the Urals, Volga River basin and Central Russia). It is most abundant and most frequently recorded at the Far East: the Jewish Autonomous Region, Primorsky Krai, Khabarovsky Krai, Amur and Sakhalin Regions. In the western part of its range - Volga River basin and Central Russia - the species is sporadically distributed, though the number of specimen records here has increased in recent years. The main habitats are sparse pine forests (on glades, roadsides, fringes) and floodplain cenoses. A.B. Ruchin, L.V. Egorov ##submission.copyrightStatement## Tue, 02 Oct 2018 10:49:58 +0200
