ladybird hippodamia variegata (goeze) (coleoptera: coccinellidae) has been reported from many parts of iran, has an important factor on equilibrium and natural regulation of acyrthosiphon pisum (harris) (hem.: aphididae) population in alfalfa. determining the population seasonal change of h. variegata and its parasitism rate by the most important parasitoid species was the aim of this study. th...

the spotted amber ladybird, hippodamia variegata (col.: coccinellidae) is one of the most prominent coccinellid predators in iran. it is omnivorous and feed on aphids and psylla. the effects of two diets brevicoryne brassicae l. (hemiptera: aphididae)and eggs of ephestia kuehniella (lepidoptera: pyralidae) on some biological aspects of hippodamia variegata (goeze) (coleoptera: coccinellidae) we...

This study was performed on an alfalfa crop located on the central plain of La Araucanía Region, Chile and in the Laboratorio de Entomología Aplicada de la Facultad de Ciencias Agropecuarias y Forestales at the Universidad de La Frontera. Certain aspects of the biology of Hippodamia variegata (Goeze) (Coleoptera: Coccinellidae) were determined, more specifically in relation to its life cycle, s...

The Adonis ladybird, Hippodamia variegataGoeze (Coleoptera: Coccinellidae) is known as an important predator of the Common pistachio psylla, Agonoscena pistaciae Burckhardt & Lauterer (Hemiptera: Psyllidae). Despite using the selective pesticides to manage the pests in the pistachio orchards, these chemicals have influenced non-target organisms like predators and parasitoids. ...

spotted amber ladybird, hippodamia variegata (goeze, 1777) (coleoptera: coccinellidae) is an important predator of aphids and some other insect pests. since shape and size variation may affect biological characteristics of an insect, multivariate analysis of shape variations in four geographically isolated populations of h. variegata (isfahan, shahrekord, shiraz, yasuj) was performed based on e...

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...
