Comparing 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 کاملeffect of different diets on some biological parameters of chrysoperla carnea (neuroptera: chrysopidae)
chrysoperla carnea is a voracious predator. it is currently mass-reared and released for biological control programs. this study was aimed at finding out the effect of different diets on biological characteristics of adult predator, and to introduce a better and cheaper artificial diet for its mass-rearing. in order to obtain a pure and physiologically homogenous population, the predator was re...
متن کاملDevelopment of Chrysoperla carnea (Stephens) (Neuroptera: Chrysopidae) on pollen from Bt-transgenic and conventional maize
Maize (Zea mays) pollen is highly nutritious and can be used by predatory arthropods to supplement or replace a carnivorous diet. We demonstrate that maize pollen can be utilized by larvae of the green lacewing, Chrysoperla carnea (Neuroptera: Chrysopidae) under laboratory conditions. Complete development on maize pollen was not possible, but 25% of neonates reached the third instar. When only ...
متن کاملeffect of different prey species on the biological parameters of chrysoperla carnea (neuroptera: chrysopidae) in laboratory conditions
the prey suitability for generalist predators is an important feature for efficient mass rearing and ipm. the green lacewing, chrysoperla carnea (stephens) is a polyphagous predator attacking several pests on various crops. this experiment was conducted under laboratory conditions at 25 ± 2 °c, 60 ± 5% r. h. and a photoperiod of 16l: 8d h. the effects of different prey species were investigated...
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 ...
