Laboratory, semi field and field tests to assess the side effects of 20 pesticides on 19 different beneficial organisms were carried out by members of the Working Group “Pesticides and Beneficial Organisms” of the International Organization for Biological Control (IOBC), West Palearctic Regional Section (WPRS). This 5th joint pesticide testing programme of the working group was carried out by 21 participants in 11 European countries. The pesticides (7 insecticides, 8 fungicides and 5 herbicides… Expand

Susceptibility of the egg parasitoid Trichogramma achaeae (Hymenoptera: Trichogrammatidae) to selected insecticides used in tomato greenhouses
The compatibility between different insecticides and the use of the egg parasitoid Trichogramma achaeae Nagaraja and Nagakartti will allow a better application of IPM programmes in tomato crops for the control of this pest species. Expand
Effects of the miticide hexythiazox on biology of Galendromus flumenis (Acari: Phytoseiidae)
Results suggest that hexythiazox would not disrupt the biological control of Banks grass mite by G. flumenis in the field. Expand
The results showed that the total effect values of all concentrations of hexythiazox were below the lower threshold thus it could be considered a harmless acaricide to this predatory mite, and in contrast, the totaleffect values of fenpyroximate, and field, as well as, one half the field concentration of abamectin were found toxic to predatory mites and above upper threshold. Expand
Toxicidade de produtos fitossanitários utilizados na cultura do pessegueiro sobre adultos de Trichogramma pretiosum
The toxicity of sixteen commercial formulations of pesticides used in peach orchard was assessed on adults of Trichogramma pretiosum Riley, 1879 by exposing the adult parasitoids to fresh dry pesticide film applied on glass plates and assessed for the number of eggs parasitized by T. Pretiosum adult female. Expand
Impacts of the pesticides imidacloprid, propargite, and pymetrozine on Chrysoperla carnea (Stephens) (Neuroptera: Chrysopidae): IOBC and life table assays
Life table assays revealed that imidacloprid and propargite had no significant effects on the intrinsic rate of natural increase, while pymetrozine caused a 34% reduction in rm value (p < 0.05). Expand
Compatibility of Entomopathogenic Fungi, Beauvaria bassiana (Bals. -Criv.) Vuill. and Metarhizium anisopliae (Metchn) Sorokin Isolates with Different Agrochemicals Commonly Used in Vineyards.
Among tested fungicides, copper hydroxide formulation was highly compatible with both fungal isolates, it even stimulated conidial germination at all tested concentrations, while other types of these agrochemicals showed various degrees of compatibility depending on the fungal isolate. Expand
Effect of glyphosate and paraquat on seed germination, amino acids, photosynthetic pigments and plant morphology of Vicia faba, Phaseolus vulgaris and Sorghum bicolor
In agriculture, the use of herbicides is necessary to prevent or restrict the growth of weeds that affect the yields of crops such as cereals and legumes. Intensive agriculture relies heavily on theExpand
Lethal and sublethal effects of three insecticides on first instar larvae of green lacewing, Chrysoperla carnea, Stephens
Flupyradifurone than clothianidin are harmless while tebufenozide is less hazardous on C. carnea population, and alpha and beta-esterase activity in treated insects with clothianIDin and flupyrADifur one was increased (compared to the control), while the enzymatic activity was reduced in insects with tebufanozide treatment.

Effects of agrochemical residues on four spider taxa: Laboratory methods for pesticide tests with web-building spiders
To both groups of spiders (the hunting and web-building), most acaricides were highly toxic, whereas herbicides and fungicides were nontoxic. Expand
Effects of pesticide residues on ground-dwelling lycosid and micryphantid spiders in laboratory tests
The lycosids were more affected by pesticides than web-building spiders because of their different life strategies, and a sprayed sand substrate matched field conditions better as a method to test the effects of pesticides on ground-dwelling spiders. Expand
A standardized method for testing the side effects of pesticides on the predacious mite,Amblyseius potentillae [Acarina: Phytoseiidae]
A method is described for testing adverse effects of pesticides on the predacious miteAmblyseius potentillaeGarman in the laboratory. It complies with the terms of the W.P.R.S./I.O.B.C. Working GroupExpand
Laboratory method for testing side effects of pesticides on juvenile stages of the predatory mite,Phytoseiulus persimilis [Acarina, Phytoseiidae] based on detached bean leaves
The method is based on detached primary bean leaves sprayed with the concentration recommended for the pesticide, or with demineralized water (controls). As soon as the spraying has dried, adultExpand
Laboratory method for testing side-effects of pesticides on the rove beetleAleochara bilineata — Adults
Generally, insecticides/acaricides had a pronounced effect on the beetles whereas fungicides and herbicides were less detrimental while Prosevor 85 was highly detrimental while Cycocel Extra and Rhodofix had no effects. Expand
Results of a joint pesticide test programme by the Working Group: Pesticides and Beneficial Arthropods
The side effect of 20 commercial pesticides on 6 different beneficial arthropods was tested by members of the IOBC/WPRS Working Group “Pesticides and Beneficial Arthropods” in 3 countries and it is hoped that the results would help other WPRS working groups and plant protection advisers in the development of rational control programmes. Expand
Toxicity of a number of pesticides to strains ofTyphlodromus pyri andAmblyseius andersoni (Acari: Phytoseiidae)
Side effects of ten pesticides used in orchards and vineyards were tested with a laboratory method on several Dutch and Italian strains of the predatory mites andersoni and showed that a test which evaluates mortality of various developmental stages and fecundity of adult females is better than one that measures only survival of adult Female.
