Biosafety of a biopesticide and some pesticides used on cotton crop against green lacewing, Chrysoperla carnea (Stehens) (Neuroptera: Chrysopidae)
Chlorpyrifos, lambda-cyhalothrin, cypermethrin, spinosad and buprofezin were tested against the second instar larvae and adults (except buprofezin) of the green lacewing, Chrysoperla carnea. The results showed that chlorpyrifos was more toxic to second instar larvae than lambda-cyhalothrin, cypermethrin, spinosad and buprofezin with LC50 values of 1.78, 8.81, 26.9, 294.36 and 997.05 ppm respect...
متن کاملBacillus thuringiensis toxin (Cry1Ab) has no direct effect on larvae of the green lacewing Chrysoperla carnea (Stephens) (Neuroptera: Chrysopidae).
Earlier studies have shown that larvae of the green lacewing predator Chrysoperla carnea are negatively affected when preying on lepidopteran larvae that had been fed with transgenic maize expressing the cry1Ab gene from Bacillus thuringiensis. To test whether the observed effects were directly caused by the Cry1Ab toxin, we have developed a bioassay which allows us to feed high concentrations ...
متن کاملComparing effects of insecticides on two green lacewings species, Chrysoperla johnsoni and Chrysoperla carnea (Neuroptera: Chrysopidae).
This study compared lethal and sublethal effects of five insecticides, chlorantraniliprole, cyantraniliprole, spinetoram, novaluron, and lambda-cyhalothrin, on adult and second instars of two green lacewing species, Chrysoperla carnea (Stephens) and Chrysoperla johnsoni Henry, Wells and Pupedis (Neuroptera: Chrysopidae) in the laboratory. Formulated pesticides were tested using concentrations e...
متن کاملbiological and life table parameters of the green lacewing, chrysoperla carnea (neu., chrysopidae) in feeding on different preys in laboratory conditions
the green lacewing, chrysoperla carnea (stephens) is one of the important predators of many pests including helicoverpa armigera (hübner) and tetranychus urticae koch. in insectaries, the larvae of this predator are mainly reared on anagasta kuehniella egg. in this research, biological and life table parameters of c. carnea in feeding on a. kuehniella egg as a laboratory prey and two natural pr...
متن کاملThe Green Lacewing, Chrysoperla carnea: Preference between Lettuce Aphids, Nasonovia ribisnigri, and Western Flower Thrips, Frankliniella occidentalis
This study investigated the prey preference of 3(rd) instar green lacewing, Chrysoperla carnea Stephens (Neuroptera: Chrysopidae), between western flower thrips, Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae), and lettuce aphids, Nasonovia ribisnigri (Mosley) (Hemiptera: Aphididae) in laboratory experiments at 25 ± 1° C and 70 ± 5% RH with five prey ratios (10 aphids:80 thrips,...
