Biotic interference of biological control of purple loosestrife [PDF]

open access: yes, 2005
Iowa State University has reared and released two European leaf-feeding beetle species to control purple loosestrife in Iowa wetlands. Expected reductions in loosestrife have not occurred, and biotic mortality factors may explain the failure of the ...

Biological control of Prays Oleae (BERN.) By chrysopids in tras-os-Montes region (Northeastern Portugal) [PDF]

open access: yes, 1999
A study was carried out in an olive grove in the Tras-os-Montes region, in the period 1993 to 1996 to establish the rate of predation of chrysopids on Prays oleae (Bern.) eggs.

Alien vs . Predator - the native lacewing Chrysoperla carnea is the superior intraguild predator in trials against the invasive ladybird Harmonia axyridis [PDF]

open access: yes
The alien invasive ladybird Harmonia axyridis (Pallas) (Coleoptera Coccinellidae) is a biological control agent of aphids and in the larval stage it is a very voracious and superior intraguild predator over most native ladybirds studied, except the large

Selectivity of Abamectin Against Chrysoperla carnea (Stephens) (Chrysopidae, Neuroptera)

open access: yesJournal of Scientific Research and Reports
Relative toxicities of abamectin along with spinosad, cypermethrin and chlorpyrifos currently used in cotton fields to control bollworms on the general predator, Chrysoperla carnea (Stephens) at egg, larvae and adult stages were evaluated under laboratory conditions in Tamil Nadu, India.

Compatibility of Chrysoperla carnea (Neuroptera: Chrysopidae) with nanoformulations of natural active substances

open access: yesJournal of Economic Entomology
Abstract Nanoformulations of essential oils (EOs) improve stability of the active ingredient, and thereby its biological activity and persistence. Because compatibility of EOs with natural enemies is not explored sufficiently, we evaluated the impact of nanoformulations of EOs (aniseed, lemon) or pure products (farnesol) on different ...
