Freshwater mussels, one of the most imperiled groups of animals in the world, are generally underrepresented in toxicity databases used for the development of ambient water quality criteria and other environmental guidance values. Acute 96‐h toxicity tests were conducted to evaluate the sensitivity of 5 species of juvenile mussels from 2 families and 4 tribes to 10 chemicals (ammonia, metals, majo ...
... Trogoderma granarium, the Khapra beetle, is a major pest of cereal grains and nuts. In this research, the lethal and sublethal effects of Artemisia sieberi Besser essential oil (EO) was evaluated against 4th instar larvae of T. granarium under the laboratory conditions. Bioassays showed that the larvae were susceptible to both contact and fumigant toxicity. In contact and fumigant toxicity the cal ...
... Adult female and male, and final instar nymph of Anisops sardeus (Heteroptera: Notonectidae) were exposed to graded concentrations of cadmium in 96h static-with-renewal acute toxicity tests, which were conducted in dry (March) and wet (May–June) seasons. The 96h LC50 values for instar V nymph, adult female and male were found to be 0.9, 0.59 and 0.51mgL−1 Cd, respectively, in wet season, while the ...
... BACKGROUND: The reported high loss rates of managed honey bee colonies have been attributed to diverse stressors including pesticides. Honey bee larvae can be exposed to pesticides in contaminated nectar, pollen and wax. Due to the difficulties of rearing larvae in vitro, research focusing on adult bee exposure to pesticides is more common than that on larva exposure to pesticides. Herein, we aime ...

Abstract:
... BACKGROUND: Understanding how species adapt to new niches is a central issue in evolutionary ecology. Nutrition is vital for the survival of all organisms and impacts species fitness and distribution. While most Drosophila species exploit rotting plant parts, some species have diversified to use ripe fruit, allowing earlier colonization. The decomposition of plant material is facilitated by yeast ...
