The gut regions of Epilachna chrysomelina are endowed with multiple enzymes that aid digestion host plant tissues. Digestive present in the E. during various developmental stages were studied laboratory to determine most destructive life stage beetle for proper management measures. Cellulase, α-glucosidase, amylase, lipase and proteinase activities observed guts. mid-gut recorded significantly ...

Purpose: To isolate and evaluate α-glucosidase inhibitors from dichloromethane extract of Croton bonplandianum Baill as probable remedy for management of diabetes. Methods: Activity-guided isolation of constituents from dichloromethane extract was carried out. Fractionation of dichloromethane extract by column chromatography on silica gel and Sephadex LH 20 using different mobile phase systems ...

background: bifenthrin and acorus calamus linn extract were evaluated against dengue vectors in the laboratory. methods: both bifenthrin and acorus calamus linn crude hexane extract were bioassayed against the adults and larval stages of dengue vectors aedes aegypti l. and aedes albopictus(skuse) in the laboratory. results: the a. calamus crude hexane extract exhibited a larvicidal activity aga...

Traditional medicines for controlling postprandial hyperglycemia includes herbs and plant extracts as well as synthetic drugs like acarbose. Synthetic drug molecules frequently have side effects such as flatulence and diarrhea. Cyanobacterial pigments have excellent anti-oxidant and free radical scavenging properties. Thus, α-amylase and α-glucosidase inhibiting activities of purified pigments ...

Septate junctions (SJs) regulate paracellular permeability across invertebrate epithelia. However, little is known about the function of SJ proteins in aquatic invertebrates. In this study, a role for the transmembrane SJ protein gliotactin (Gli) in the osmoregulatory strategies of larval mosquito (Aedes aegypti) was examined. Differences in gli transcript abundance were observed between the mi...

Purpose: To evaluate the α-glucosidase inhibitory activity of Croton bonplandianum Baill as a probable remedy for the management of diabetes. Methods: Dichloromethane and methanol extracts were prepared and screened for their α-glucosidae inhibitory activity using standard in vitro α-glucosidae inhibition assay. Acarbose was used as positive control. Results: α-Glucosidae inhibition activity of...

fractions obtained from partitioning of aerial methanolic extract of euphorbia aellenii with chloroform (e2), ethyl acetate (e3), n-butanol (e4) and water (e5) were investigated in vitro for their phytotoxicity, insecticidal, anti-leishmanial, cytotoxicity, antibacterial and antifungal activities. sample e2 appeared to have significant phytotoxic activity. in the insecticidal screening study on...

The Bombyx mori (Lepidoptera: Bombycidae) midgut undergoes remodeling during the larval-pupal metamorphosis. All metamorphic events in insects are controlled by mainly two hormones: 20-hydroxyecdysone (20E) and juvenile hormone (JH). Fenoxycarb, O-ethyl N-(2-(4-phenoxyphenoxy)-ethyl) carbamate, has been shown to be one of the most potent juvenile hormone analogs against a variety of insect spec...
