influence of grain type on the susceptibility of tribolium confusum adults to three diatomaceous earth formulations
نویسندگان
چکیده
insecticidal efficacy of three diatomaceous earth (de) formulations, debbm, dea and f2 was evaluated on three different wheat cultivars, chamran, verinak and behrang, against tribolium confusum jacqueline du val. des were applied at the rates of 100, 200 and 300 mg/kg. bioassays were carried out on wheat at 27 ± 1 °cand 55 ± 5% rh in continuous darkness. mortality of adults was counted after 2, 7 and 14 days of exposure. adults of t. confusum were the most susceptible to debbm in behrang. so that debbm concentration of 100 mg/kg after 7 days of exposure caused 98% mortality which reached 100 after 14 days. therefore, behrang was the most tolerant cultivar to t. confusum infestations. furthermore, debbm was more effective than the other two testedformulations.

Efficacy of diatomaceous earth formulations admixed with grain against populations of Tribolium castaneum
The efficacy of diatomaceous earth (DE) to control stored-products Coleoptera on stored grain was examined against several populations of the red flour beetle, Tribolium castaneum (Herbst). Four commercially available DE formulations were tested: INSECTO, Perma-GuardTM, Protect-It and the diatomite used for the production of Dryacide, each at six concentrations (100-1000 ppm). A great variation...

بر اساس نظریه افلاطون در باره شعر خلاقیت هنری مورد انتقاد قرار گرفته است. نظریه کلی در مورد شعر این بود که شعر از ظواهرتقلید میکند و نه حقیقت. چون سایه ای از حقیقت است. اما با پیدایش فلسفه نو افلاطونی، انتقاتات قبلی در مورد شعر و شاعری اصلاح شد. فلوطین در کتاب انئید، اساس خلق هنری را بر محور مُثل افلاطونی قرار داد. وی باور داشت که هنر مندان در خلق آثار هنری، تحت تاثیر مُثل افلاطونی بوده و عوالمی ...
Sublethal Exposure to Diatomaceous Earth Increases Net Fecundity of Flour Beetles (Tribolium confusum) by Inhibiting Egg Cannibalism
Population regulation results from an interplay of numerous intrinsic and external factors, and for many insects cannibalism is such a factor. This study confirms a previously-reported observation that sublethal exposure to the fossilized remains of diatoms (i.e. diatomaceous earth) increases net fecundity (eggs produced minus eggs destroyed/day) of flour beetles, Tribolium confusum. The aim wa...
