The objectives of this research were to investigate the effects of Alysicarpus vaginalis L. (Alyce clover) leaf extracts prepared with ethyl acetate and methanol on in vitro activities like antioxidant, antimicrobial and cytotoxic, as well as on some in vivo activities like analgesic and neuropharmacological properties in an animal model. Study Design: Phytochemical screening was used as the primary method of evaluation for both the ethyl acetate (EAEAV) and methanolic extract (MEAV) of Alysicarpus vaginalis (L.). Because of the pharmacological interest in the plant's constituent components, it was decided to investigate its potential on in vitro activities, such as antioxidant, cytotoxic and antibacterial. Whether or if the observed effects on its in vivo analgesic and neuropharmacological properties in animal models are statistically significant. Place and Duration of Study: This investigation was performed in

“…A method of dosing spruce budworm with Bacillus thuringiensis, using a balsam fir (Abies balsamea [L.] Mill.) needle, has been described by Moore & Morris (1982). This present paper describes another apparatus used to dose spruce budworm larvae with N. fumiferanae and some of the effects of sub-lethal doses of the parasite on its host.…”

SummaryVarious dosages of the microsporidian parasite, Nosema fumiferanae were fed to 12-day-old larvae of Choristoneura fumiferana using a previously undescribed bioassay capsule. A spore dose of 3 × 104 resulted in 92% infection and a significant reduction in pupal weights, adult female longevity and a mean spore concentration of 1·5 × 107/living adult. Significant mortality (68%, combined larvae and pupae) did not occur until larvae ingested 3 × 107 spores; this dose produced a mean of 1·8 × 107 spores in dead larvae and 3·6 × 107 and 4·6 × 107 spores in dead male and female pupae respectively.

The effectiveness of several commercially available sunlight screens in protecting Bacillus thuringiensis Berliner (B.t.) against inactivation by solar irradiation was assessed in the laboratory and field. Spore viability and residual insecticidal activity of B.t. were rapidly reduced by solar radiation in the range of 300 to 400 nm wavelength. The addition of ultraviolet absorbers, Uvinul DS49 and Erio Acid Red, to a Thuricide spray formulation prolonged the insecticidal residual activity on coniferous trees, resulting in greater effectiveness against the spruce budworm, Choristoneura fumiferana (Clem.), compared with a formulation lacking these protectants.
