Many insects possess adhesive foot pads, which enable them to scale smooth vertical surfaces. The function of these organs may be highly affected by environmental conditions. Ladybird beetles (Coccinellidae) possess dense tarsal soles of tenent setae, supplemented with an adhesive fluid. We studied the attachment ability of the seven-spotted ladybird beetle (Coccinella septempunctata) at differ...

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...

the distribution pattern of pest population is one of the factors not only effects on sampling program and data analysis method, but also can be used to measure the density of pests and their natural enemies. thus, the spatial distribution pattern of the pea aphid, acyrthosiphon pisum harris (hem.: aphididae) and its two major predators, hippodamia variegata goeze (col.: coccinellidae) and cocc...

Hitherto six species of scuttle fly of the cosmopolitan genus Phalacrotophora Enderlein were known from Europe, of which only two were recorded from Britain and the Netherlands (Disney, 1991). The larvae of these two species, P. berolinensis Schmitz and P. fasciata (Fallén), are parasitoids of the pupae of Coccinellidae (ladybird beetles) (Disney, Majerus & Walpole, 1994). The larval habits oft...

Bactericera cockerelli (Sulc) (Hemiptera: Triozidae) is a major pest of potato, (Solanum tuberosum L.), tomato (Solanum lycopersicum L.), and peppers (Capsicum spp.). The purpose of our research was to identify and determine the impact of natural enemies on B. cockerelli population dynamics. Through 2 yr of field studies (2009-2010) at four different sites and laboratory feeding tests, we ident...

During the past four decades, several species of aphidophagous Coccinellidae became established in North America, including Coccinella septempunctata, Harmonia axyridis, Hippodamia variegata, and Propylea quatuordecimpunctata. After their establishment, unknown circumstances favoured a rapid increase in population densities and distribution of H. axyridis and C. septempunctata at localities hun...

Six different indigenous plants were screened for antifeedant and insecticidal activity against fourth instar larvae of Epilachna beetle, Henosepilachna vigintioctopunctata, which is a severe pest on brinjal. Among the plants screened, Achyranthes aspera showed higher activity against the selected pest. Ethyl acetate extracts of A. aspera showed higher antifeedant index and insecticidal activit...

Some experiments indicate the ability of coccinellids to significantly suppress aphid abundance. Exclusion of predators by caging aphid-infested plants has repeatedly resulted in higher aphid populations and greater aphid population growth rates. However, aphidophagous coccinellids have never proved effective in controlling aphid populations in the field. To resolve this apparent contradiction,...

Scymnus incisus H. Lindberg, 1931 resurrected name is a valid species, not a synonym of Nephus (Nephus) peyerimhoffi (Sicard, 1923). Nephus quadrimaculatus bucciarellii Canepari & Tedeschi, 1977 is removed from synonymy with N. (N.) ulbrichi Fürsch, 1977 and synonymized with N. (N.) schatzmayri Canepari & Tedeschi, 1977 syn. nov. Hyperaspis inexpectata Günther, 1959 resurrected name is a valid ...

This study was carried out in order to determine the predator and parasitoid species that feed on soft scale insect (Hemiptera: Coccidae) orchards of Diyarbakır Elazığ Provinces Turkiye 2017 2018. Visual identification rearing methods were used. Eight predatorory belonging families Coccinellidae (4) Cybocephalidae (1) (Coleoptera), Forficulidae (2) (Dermaptera), Chrysopidae (Neuroptera), detect...
