The species Pentilia egena Mulsant is an important predator of armored scales that occur in citrus orchards in Brazil. To intensify this biological control, knowing bioecological aspects in necessary for the improvement of massal insect rearing. This research investigated the influence of temperature (19C, 24C and 29C) on the number of eggs laid by P. egena and the number of Aspidiotus nerii Bo...

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 ...

Coccinellids are important biological control agents and aphid predators in horticultural crops around the world. Neotropical Cycloneda sanguinea, Eriopis connexa Coleomegilla quadrifasciata octodecimpustulata, exotic Harmonia axyridis (all Coleoptera: Coccinellidae), that mainly feed on aphids. In this work we described abundance of these coccinellid species their spatial temporal cooccurrence...

In New York, the primary coccinellid in corn and sweet corn (Zea mays, L.) has historically beenColeomegillamaculata (DeGeer).However,Harmonia axyridis (Pallas)has alsobeen observed the last few years. The objectives of this study were to document the level of establishment of both species in corn and sweet corn and to understand their interactions. The temporal and within-plant distributions o...

The functional response parameters and patterns of three coccinellid predators, Cheilomenes sexmaculata, Propylea dissecta, and Coccinella transversalis (Coleoptera: Coccinellidae) were evaluated to find out how these predators respond at two different prey species across various prey densities levels. All three predators exhibited a decelerating curve Type II response determined by a logistic ...

Incidence of parasitism is often underestimated because ‘ghost’ parasitoids (dead unemerged or those that have emerged leaving the host carcasses) are difficult to detect and identify. This study demonstrates use melting curve analysis (MCA) carcasses can identify DNA ghost even a month after death. The coccinellid hosts Cycloneda sanguinea, Eriopis connexa, Harmonia axyridis Hippodamia converg...

In order to determine morphological characteristics of Fusarium species associated with root and stem of maize in Kermanshah province, duringtwo growing seasons of 2006-2008, 110 samples, mostly from diseased plants were collected from different geographic regions of the province. The collecting localities were Gilan Gharb, Sarpol Zohab, Qasr Shirin, Sonqor, Kangavar, Bisotun, Ravansar, Kermans...
