The effect of Cry proteins of Bacillus thuringiensis on the green lacewing (Chrysoperla carnea) was studied by using a holistic approach which consisted of independent, complementary experimental strategies. Tritrophic experiments were performed, in which lacewing larvae were fed Helicoverpa armigera larvae reared on Cry1Ac, Cry1Ab, or Cry2Ab toxins. In complementary experiments, a predetermine...

Pecan foliage is attacked by three species of aphids [Monellia caryella (Fitch), Melanocallis caryaefoliae (Davis), and Monelliopsis pecanis Bissell], resulting in damage that can reduce tree nut yield. In this study, we assayed the ovipositional response of the green lacewing Chrysoperla rufilabris (Burmeister) to M. caryella and M. caryaefoliae at high and low aphid densities and the developm...

The common pistachio psylla, Agonoscena pistaciae Burckhardt and Lauterer (Hem.: Aphalaridae), is one of the most important pests of pistachio orchards in Iran. Green lacewing, Chrysoperlacarnea, as a general predator found abundantly in Iranian pistachio gardens, loses its performance under the impression of pesticides spraying. Nowadays, considering environmental pollutions,...

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...

The charismatic lance lacewing genus Gryposmylus Krüger, 1913 (Osmylidae: Protosmylinae) from South East Asia is revised with a new species (Gryposmylus pennyi sp. n.) described from Malaysia. The genus is diagnosed and both species in the genus redescribed and figured. An extraordinary example of morphological convergence is presented, with disruptive camouflaging wing markings in Gryposmylus ...

Red imported Þre ants, Solenopsis invicta (Buren) (Hymenoptera: Formicidae), are an invasive species found in high densities throughout southeastern agricultural systems. We tested the hypothesis that Þre ants tend cotton aphids, Aphis gossypiiGlover (Homoptera: Aphididae), and thus release them from predation by lady beetle larvae, Coccinella septempunctata L. and Hippodamia convergens Guerin-...

A new species of the charismatic green lacewing genus Glenochrysa Esben-Petersen is described from northern Western Australia. Glenochrysa minima sp. n. represents one of the smallest species of the genus. A key to species of Australian Glenochrysa is presented.

abstract in order to find out a better and cheaper artificial diet for mass rearing of common green lacewing, chrysoperla carnea, an experiment was conducted using completely randomized design (crd) with 4 replications and 5 observations. in this study were used three diets [a mixture of honey, yeast and distilled water (1:1:1), a mixture of honey, yeast plus extract of angomois grain moth eggs...
