Few toxicity data exist in the literature on of chemicals to predatory mite Hypoaspis aculeifer, but no information is available its avoidance response. To assess relevance behavior H. aculeifer and relative sensitivity comparison with other invertebrates, reproduction tests were conducted 7 using standardized guidelines. The (deltamethrin, chloropyrifos, dimethoate, Cu, NaCl, phenanthrene, boric acid) selected so as cover varying chemical classes. For all 3 pesticides tested, response...
The oribatid mite Oppia nitens has been suggested as a test species for ecotoxicological assessment of contaminated boreal soils. Knowledge the ecotoxicity pollutants different modes action to this is necessary assess its relative sensitivity in comparison with other invertebrates. toxicity four metals and two organic chemicals O. was evaluated over 28- or 35-d period. Mite survival, reproduction, tissue accumulation were assessed at end test. Reproduction more sensitive endpoint than...
Indiscriminate use of pesticides is rampant in most parts Africa, but only scanty ecotoxicological data exist for the protection soil organisms-and these were usually obtained under temperate conditions, including Organisation Economic Co-operation and Development (OECD) standard test protocols. In order to assess effects 3 commonly used (deltamethrin, dimethoate, chlorpyrifos) on fauna noncontaminated natural soils collected from Nigeria Tunisia. addition, 2 common soils, OECD artificial...
Abstract Survival and reproduction soil toxicity tests for a new mite test species, Oppia nitens, have recently been developed boreal ecosystems; however, the require 28 to 35 d. Avoidance potential allow rapid preliminary screening assessments of soils. The objective this investigation was determine relevance avoidance with oribatid O. nitens as short in lower‐tier environmental risk assessment. We assessed effects properties chemicals on behavior well minimum time required obtain...
Experiments were conducted to examine whether the foliar application of zinc (Zn) could mitigate adverse effects heat stress on pakchoi plants. Two varieties (Aikangqing and Wuyueman) applied with ZnSO4·7H2O (0%, 0.02%, 0.05%, 0.10%, 0.20%, 0.40%, 0.60%, 0.80%), then subjected two temperature levels (22°C/16°C, day/night; 40°C/30°C, day/night). Heat decreased net photosynthetic rate (Pn) (50.65% 62.14% for Aikangqing Wuyueman, respectively), chlorophyll content, fluorescence ratio (Fv/Fm),...
The tropical stingless bee, Meliponula bocandei Spinola, 1853 is an important pollinator in West Africa but there no study on the effect of pesticides this species. This assessed effects cypermethrin, a common pyrethroid survival, taste (sucrose sensitivity), and biochemical responses M. bocandei. markers were superoxide dismutase [SOD], catalase [CAT], glutathione S-transferase (GST), reduced [GSH]), acetylcholinesterase [AChE]) as well glucose, trehalose total protein concentrations. Test...
Abstract Northern boreal forests often experience forest dieback as a result of metal ore mining and smelting. The common solution is to lime the soil, which increases pH, reducing toxicity encouraging recovery. In certain situations, however, such in Flin Flon, Manitoba, Canada, liming has yielded only moderate benefits, with some locations responding well other not at all. an effort increase effectiveness ecorestoration strategy, authors investigated if these differences responsiveness...
