fermentation of 49 carbohydrates and oxidation and assimilation of 96 substrates were examined for ten beauveria bassiana isolates. principal component analysis indicated that there are significant differences among isolates for utilization of some substrates. esculine and d- glucose were positively fermented by all isolates. isolates were grouped into four clusters on the basis of hierarchial ...

Three known Cinchona alkaloids of the quinine type, quinine (1), cupreine (2), cinchonine (3), and the possible artifact cinchonine-HCl (3-HCl), along with two new ones, acetylcupreine (4) and N-ethylquinine (5), have been isolated from the bark of Remijia peruviana (Rubiaceae). Their stereochemical structures were established by high resolution NMR spectroscopy. Alkaloids 2-4 had antifeedant e...

Naive mated female cabbage looper moths, Trichoplusia ni Hübner, responded in a flight tunnel to potted potato plants ( Solanum tuberosum ). Percentages of moths attracted to uninjured potato plants, mechanically-damaged potato plants, and potato plants treated with regurgitant from larvae of the Colorado potato beetle, Leptinotarsa decemlineata Say, were similar, indicating no effect of plant ...

Experiments were conducted during three seasons to quantify the relationship between yields of late-maturing potato variety and variation in densities of second-generation larvae of the Colorado potato beetle (CPB), Leptinotarsa decemlineata (Say), in Connecticut and to develop alternative strategies to regular insecticide applications for maintaining commercially acceptable second-generation C...

Five annonaceous acetogenins, rolliniastatin-1 [structure: see text], rolliniastatin-2 [structure: see text], laherradurin [structure: see text], squamocin [structure: see text], annonacin [structure: see text], and rotenone as a reference, differing in their NADH oxidase inhibition activity, have been evaluated for antifeedant, insecticidal, trypanocidal and cytotoxic effects on insect, mammal...

Six Beauveria bassiana (Balsamo) Vuillemin isolates were obtained from Reticulitermes flavipes (Kollar) and Coptotermes formosanus Shiraki in the U.S. and China. These isolates, plus the B. bassiana isolate 26037 from American Type Culture Collection that was isolated from Colorado potato beetle (Leptinotarsa decemlineata (Say)) were compared against C. formosanus and R. flavipes in the laborat...

The lethal effects of Beauveria bassiana BIM-001 (1x106 spore mL-1, 1x107 1x108 mL-1), Fusarium subglutinans 12A (obtained from cotton aphid in Adana-Karata?) and the commercial preparation 1.5% B. strain Bb-1 (250 mL da; mL-1) (Nostalgist SL) on Leptinotarsa decemlineata were investigated. isolates applied to eggs, larvae (1st, 2nd, 3rd, 4th larval stages) adults L. by spraying laboratory cond...
