'Candidatus Liberibacter asiaticus' (Las) is the primary causal agent of huanglongbing (HLB), the most devastating disease of citrus worldwide. There are three known insect vectors of the HLB-associated bacteria, and all are members of the Hemiptera: Diaphorina citri (Psyllidae), Trioza erytreae (Triozidae), and Cacopsylla (Psylla) citrisuga (Psyllidae). In this study, we found that another hem...

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. ...

the ladybird beetle, hippodamia variegata (goeze) (coleoptera: coccinellidae) is one of the most important natural enemies of the common pistachio psylla, agonoscena pistaciae burckhardt and lauterer (hemiptera: psyllidae). the effects of hexaflumuron and spirodiclofen were investigated on development and carbohydrates and total lipid contents of 4th instar larvae of h. variegata. the insectici...

the green lacewing chrysoperla carnea (stephens) (neuroptera: chrysopidae) is one of the important natural enemies of pest insects. present study conducted to evaluate the side effects of some plant extracts, calotropis procera (willd.) r. br. (asclepiadaceae), fumaria parviflora lam. (fumariaceae), eucalyptus spp. (myrtaceae) and pesticide amitraz on biological parameters of the second instar ...

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...

Petroleum based mineral oils have been used for insect pest control for over a century (Agnello, 2002). However, their use is as current today as it was before the advent of chemical insecticides, given that they are compatible with modern sustainable management practices. These products pose a number of advantages over conventional pesticides and they have very low mammalian toxicity, low resi...

insect natural enemies selected for such specific traits as faster developmental times, longer survivor, increased fecundity, and larger body size might be considered during production of biological control agents in certain situations. for instance, traits related to developmental rates may be selected for, if genetically based variation exists within temperature-dependent responses. hippodami...
