The predator Chrysoperla externa (Hagen, 1861) (Neuroptera: Chrysopidae) is a polyphagous species that has, among its wide range of acceptable prey, the aphid Macrosiphum rosae (Linnaeus, 1758) (Hemiptera: Aphididae), an important pest rose plants. We assessed consumption nymphs and adults M. by C. larvae, predatory efficiency, larval survival under different predator:prey ratios, densities aph...

In this study, functional and numerical response tests, which are important components in the selection of biological control agent, were carried out. trials, amount food consumed, attack rate (a) handling time (Th) calculated for each developmental period, depending on number preys given after 24 hours. The obtained results evaluated with Holling. experiments, development predator insect was e...

UV-C irradiation is known to enhance plant resistance against insect pests. In the present study, we evaluated effects of low doses on Macrosiphum rosae infesting greenhouse rose (Rosa x hybrida) plants. The application 2.5-kJ/m2 leaves before infestation induced anti-herbivore and negatively affected aphid fecundity. No eggs first instar nymphs were recorded irradiated leaves, whereas an avera...
