Interactions between lady beetles and the European fire ant (Myrmica rubra L.) tending potato aphids [Macrosiphum euphorbiae (Thomas)] were compared in the laboratory. Lady beetle species native to North America (Coccinella trifasciata perplexa Mulsant, Coleomegilla maculata lengi Timberlake, Hippodamia convergens Guérin-Méneville) and non-native species of Palearctic origin [Coccinella septemp...

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...

An extensive survey of predatory Coccinellid beetles (Coleoptera: Coccinellidae) was conducted in the Chitral District, Pakistan, over a period of 7 months (April through October, 2001). A total of 2600 specimens of Coccinellids were collected from 12 different localities having altitudes from 1219.40-2651.63 m. Twelve different species belonging to 9 genera of 3 tribes and 2 sub-families were ...

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...

In this study, the orientation of two different predator species [(Coccinella septempunctata L., Hippodamia variegata (Goeze) (Coleoptera: Coccinellidae)) to aphids [Aphis fabae Scopoli and Acyrthosiphon pisum Harris (Hemiptera: Aphididae)] was investigated. Y-type olfactometer which made glass material with one entrance exit openings used in study. Different applications were applied ends pred...

This study was conducted to determine the overwintering insect biodiversity in pistachio orchards of Middle Euphrates Valley, Turkey during 2017 and 2018 by artificial shelters. Artificial shelters were established five ?ehirba??, Karaba?, Meyanca, Baraj Ekenek locations. Ten trees selected within each orchard these covered with a burlap sack rest corrugated cardboard through September January....
