Soil diversity, pH, electrical conductivity and organic matters are dominant disturbance factors on community composition of soil mites. Impacts of these factors were assessed on the species composition of soil mites at Dakahleia and Kafrelshikh governorates in six different sites. In total, 14 families, 30 genera, and 37 mite species belonging to the four sub-orders Gamasida, Actinedida, Oribatida and Acaridida were recorded. Mite abundance and diversity in the soil in Kafrelshikh was poor compared with Dakahleia sites. The effect of soil type on mite community composition was significant. PH and organic matters have been established as good indicators for soil fertility. Soil mites were affected by soil fertility as it was observed that soil mites population increased with increasing nutrients. This study provided important information on soil mite populations in cultivated soils and could provide baseline data for studies of bioindicators of soil quality. In conclusion soil mites responded to land type, pH, EC (ds/m) and organic matter level.https://ajesa.journals.ekb.eg/article_4925_b0e56af2aa55e3fdeb772043f042e64e.pdfEgyptian Society of Acarology (J.E.S.A)Acarines: Journal of the Egyptian Society of Acarology1687-46337120130701Effect of Some Acaricide Treatments on Some Biological Aspects of the Two-Spotted Spider Mite Tetranychus urticae Koch and its Predator Phytoseiulus persimilis Athias-Henriot4751492610.21608/ajesa.2013.4926ENAlyaaTawfikPlant Protection Research Institute, Agricultural Research Center, Dokki, Giza, EgyptL.

Increase in efficiency was detected with increasing temperature, as LC50 values was decreased from 0.356 to 0.269 and 0.217 mg/l when temperature increased from 20° to 25° and 35°C; respectively. The two predators, Phytoseiulus persimilis A. H. and Neoseiulus californicus (McGr.) proved to be more tolerant to mentol vapor than T. urticae.

The toxicity of tested pesticide-residues that showed high toxicity to the predators in spraying method was also evaluated. Results showed that fungicides; carbendazim and kresoxim methyl, were non toxic to the tested predators, hexaconazol and chlorothalinol were slightly toxic; while difenoconazole and pencocanazole were moderately toxic. For insecticides deltamethrin was non toxic to phytoseiid mites, emamectin benzoate and diflubezuron were slightly toxic, cypermethrin and tiflubenzuron were moderately toxic, whereas carbusolfan, dimethoate, chlorepyrifos ethyl, and dimethoate + deltamethrin were highly toxic. As for the toxicity of pesticide-residues, the toxicity of cypermethrin, diflubezuron, and teflubezuron decreased to become slightly toxic when the predators were placed on the leave-discs just after the pesticides were dried out, whereas the toxicity of carbusolfan, chlorepyrifos ethyl and dimethoate did not decrease until 48 hrs passed after application. The toxicity of the insecticide to T. urticae varied, it ranged from non toxic (diflubenzuron) to highly toxic (chlorepyrifos ethyl, cypermethrin, dimethoatee, diltamethrin + dimethoatee, deltamethrin, and emamectin benzoate).

The acaricidal activity of the tested compounds against T. urticae was assessed by the slide dip and leaf disk dip techniques. Data showed that slide dip technique was efficient method to screen abamectin, chlorfenapyr and fenpyroximate; while the leaf disk dip technique was efficient method to determine the toxicity of ethion and etoxazole. The difference between the compounds may be due to their mode of actions. Results indicate that ethion, chlorfenapyr and etoxazole are very less toxic to P. persimilis adult females than those of T. urticae.
