Survivorship of larvae of the small hive beetle, Aethina tumida Murray (Coleoptera: Nitidulidae), was measured after they were raised on one of six diets. The effects of container shape (wide and shallow vs. narrow and deep), soil depth (0, 0.5, 1.0, 2.0, 4.0, and 8.0 cm), and temperature (28°, 32°, or 35° C) on pupation success was measured. Diet influenced larval survivorship, but did not hav...

Mercury (Hg), as the most potentially hazardous heavy metal, has accumulated in aquatic environment and caused concern about its safety. To test toxic effects of mercury chloride (Hg2+) on rare minnow (Gobiocypris rarus), acute toxicity Hg2+ to embryos, newly hatched larvae, juvenile fish, short-term developmental embryo sac-fry stages, were investigated. The 96-h LC50 values fish 0.56, 0.07, 0...

Beetles of the family Passalidae (Coleoptera: Scarabaeoidea) are termed subsocial. The insects inhabit rotten wood as family groups consisting of the parents and their offspring. The Japanese species Cylindrocaulus patalis has the lowest fecundity among passalids because siblicide occurs among the first-instar larvae; accordingly, parental care toward the survived larva is the highest among Pas...

Decorator crab Camposcia retusa is a popular marine ornamental species; however, it has never been bred previously. To establish feeding regime for C. larvae, which include two zoeal and megalopal stage, three experiments were conducted. In all experiments, ≥60% of unfed 1st (Z1) larvae survived to the next combined with orange guts observed in fed Artemia, suggesting Z1 are facultative lecitho...

The developmental time and survival to eclosion of Anopheles hermsi Barr & Guptavanij fed monotypic and mixed diets of ten food types were examined in laboratory studies. Larvae fed monotypic diets containing animal detritus (freeze-dried rotifers, freeze-dried Daphnia pulicaria, and TetraMin® fish food flakes) and the mixotrophic protistan Cryptomonas ovata developed faster and survived better...

Exposure to contaminants in the environment has been suggested as a contributing cause of ongoing declines in populations of amphibians reported in certain locations around the world. In the current study, responses of the wood frog (Lithobates sylvaticus) to exposure to triphenyltin (TPT), a commonly used fungicide, during the larval period were characterized. Exposure of L. sylvaticus to 0.1,...

Genetically modified (GM) soybeans expressing Cry1A.105/Cry2Ab2/Cry1Ac (event MON 87701 × 89788 87751 87708) and Cry1Ac 89788) from Bacillus thuringiensis Berliner (Bt) are valuable technologies for managing key lepidopteran pests of soybean in South America, but do not provide stand-alone protection against Spodoptera species. Here, we evaluated the use these Bt their integration with insectic...

The design and evaluation of antimicrobial activities an isonitrosomalononitrile silver(I) salt was reported. This highly stable water-soluble silver shows Minimum Inhibitory Concentrations (MIC) values ranging from 0.15 to 5 µg/mL towards both sensitive resistant Gram-positive negative bacteria. Furthermore, this has been investigated for its ability treat a S. aureus infected Galleria mellone...
