Aphid Species Affect Foraging Behavior of Coccinella septempunctata (Coccinellidae: Coleoptera).
BACKGROUND Flowers are admirable in scenic good looks and artistic beautification. These are also playing necessary roles in therapeutic preparations. Aphid is an important sucking pest of various flowers in ornamental territories and it is generally controlled by predators, so it was necessary to evaluate which aphid species affect the predator more or less. MATERIALS AND METHODS Biocontrol ...
متن کاملComparison of the wing polyphenic response of pea aphids (Acyrthosiphon pisum) to crowding and predator cues.
1. Pea aphids (Acyrthosiphon pisum Harris; Hemiptera: Aphididae) exhibit transgenerational wing polyphenism, in which unwinged females produce genetically identical winged offspring in response to environmental cues such as overcrowding and predation risk that indicate poor habitat quality. 2. Laboratory experiments were carried out to explore the intensity of the wing polyphenic response of pe...

متن کاملTemperature-dependent development and demography of Scymnus subvillosus (Coleoptera: Coccinellidae) reared on Hyalopterus pruni (Homoptera: Aphididae).
The development, survival, and fecundity of Scymnus subvillosus (Goeze) (Coleoptera: Coccinellidae) were studied at 20, 25, 30, and 35 degrees C, 60 +/- 5% RH, and a photoperiod of 16:8 (L:D) h (5,000 lux) under laboratory conditions. The total developmental time from egg hatch to adult eclosion ranged from 22.6 d at 20 degrees C to 10.6 d at 35 degrees C. The developmental rates of the egg sta...
متن کاملlethal and sublethal effects of imidacloprid and pirimicarb on the melon aphid, aphis gossypii glover (hemiptera: aphididae) under laboratory conditions
the toxicity of imidacloprid and pirimicarb for all stages of the melon aphid, aphis gossypii glover, were investigated under laboratory conditions (25 ± 1 oc, 65 ± 5% r.h. and a photoperiod of 16:8 (l: d) h.) using a leaf dipping method. these pesticides were very toxic for first instar nymphs of a. gossypii with lc50 values of 17 and 220.2 ppm for imidacloprid and pirimicarb, respectively. fo...
