“…using the recommended field rate. Similar results have been found for Carabidae and Lycosidae [22–24], with dimethoate being very toxic to the carabid Pterostichus melanarius (Illiger) and causing varying levels of mortality to spiders. It has also been found to reduce densities of most nontarget arthropod groups in cereals [25] and was found to have a considerable impact on densities of sawfly larvae [16,17].…”

Six insecticides, a carbamate (pirimicarb), four pyrethroid/mixtures (tao-fluvalinate, zeta-cypermethrin, deltamethrin, and pirimcarb+deltamethrin), and an organophosphate (dimethoate), registered for use within cereals, were field-tested for toxicity to beneficial nontarget invertebrate groups important as food for farmland birds. Compared to the control and the other compounds, pirimicarb was the least toxic for most invertebrate groups examined. The pyrethroids and pyrethroid mixture significantly reduced numbers of many of the nontarget groups compared to the control and pirimicarb. Tao-fluvalinate was the least toxic pyrethroid tested when compared to the other compounds. Toxicity was further tested on larvae of graminivorous sawflies, an important chick- food group, using field-sprayed plants in laboratory and semifield trials. None of the pyrethroid and carbamate compounds and mixtures was as toxic as the organophosphate, but all were more toxic than the control. The semifield experiments provided a useful way of determining potential insecticide impact on this nontarget group where field populations are often too low for field trials to have statistically conclusive results.

“…Pirimicarb is a selective systemic aphicide with contact, stomach and respiratory action (Tomlin, 1991). Lethal effects of pyrethroids on carabids have been documented both in the laboratory and in the field (Pullen et al ., 1992; Cilgi et al ., 1996; Gyldenkærne et al ., 2000). Deltamethrin is toxic at least to Agonum dorsale (Pontoppidan), D. atricapillus , Bembidion lampros (Herbst), B. obtusum Audinet‐Serville (Cilgi et al ., 1996), Nebria brevicollis (F.) and P. melanarius (Pullen et al ., 1992).…”

“…The application rate of Deltamethrin was 5 g of active ingredient (AI)/ha at normal dosage, reduced to 1.25 g AI/ha at quarter dosage. In the laboratory, Deltamethrin has been found to cause nearly 100% mortality of A. dorsale , D. atricapillus , B. lampros and B. obtusum at a field application rate of 6.25 g AI/ha (Cilgi et al ., 1996). According to laboratory tests, an application rate of 1.25 g AI/ha (quarter dosage) may result in 50% mortality of A. dorsale , but only 10–20% mortality for D. atricapillus and Bembidion spp.…”

1 The effects of reduced insecticide and herbicide dosages on total dry mass of carabids and their generic components were examined using fenced pitfall traps in winter wheat fields on three farms in Southern Zealand, Denmark. 2 The estimated total dry mass of carabids increased by 25% when the pesticides were reduced to one fourth of the normal application rates. 3 At reduced dosages, the activity of the genus Pterostichus was increased by 62%. The activities of Loricera and Demetrias were increased by 67% and 56%, respectively, although significant interaction terms indicated that the dosage effect was not uniform for these genera on all farms. Calathus tended to be more numerous with reduced pesticide applications. By contrast, catches of Bembidion, Synuchus and Trechus decreased by up to 45% at reduced dosages. 4 A higher weed cover due to reduced herbicide applications probably benefited most species, except those having habitat associations with sparse vegetation such as the field-inhabiting Bembidion and Synuchus. 5 The higher activity of larger carabids may lead to enhanced predation on smaller carabids and hence different carabid assemblages.

“…The density of Bembidion lampros in laboratory conditions is pesticide dependent (54). High sensitivity of Bembidion obtusum to a laboratory application of Pirimicarb insecticide was proven by Cilgi et al (55). The negative influence of an application of chemical plant protection preparations on small zoophages (Epaphius secalis and Bembidion guttula) was also observed in field experiments (52).…”

Background and Purpose: Various crop cultivation systems may affect field-dwelling organisms, representatives of both harmful and beneficial entomofauna. In this paper, attention was drawn to one of the factors which distinguishes organic and integrated farming, that is the application of chemical plant protection preparations. Materials and Methods: The experiment was conducted in Poland, at the Experimental Station IOR-PIB in Winna Góra near Środa Wielkopolska, on crop fields of lupine and pea. The experiment was composed of a block of organic fields (no chemical plant protection preparations) and another block, where a plant protection programme was carried out in line with the integrated agricultural production guidelines. Carabidae were caught into modified Barber traps, from May to the end of July in 2006, 2010 and 2014. Results and conclusions:As a result of our study, 8 848 specimens belonging to 67 species of Carabidae were collected. The most numerous species collected in the pea and lupine were: Poecilus cupreus, Pterostichus melanarius, Harpalus rufipes, Bembidion femoratum, Bembidion quadrimaculatum and Bembidion tetracolum. Overall, our results demonstrate that an application of chemical plant protection preparations decreases the abundance and species diversity of carabid beetles assemblages in studied crops and induces changes in particular life traits of carabids fauna. After the treatment, the abundance of large carabid beetles diminishes and their place is occupied by small zoophages. Furthermore, the forecrop could be one of the factors that influence assemblages of carabids on crop fields.IntRoductIon T he use of pesticides causes endless controversies. Every synthetic preparation which enters the natural environment has a direct or indirect influence on many biotic elements and processes on a scale that may encompass whole ecosystems (1). Even the chemical products that do not seem toxic to humans, animals or plants can affect agricultural ecosystems adversely. The use of pesticides can have a variety of negative agricultural, environmental and health effects (2, 3, 4). Progressive specialization in agriculture and environmental pollution due to the excessive use of chemical plant protection products has stimulated a search for pro-ecological solutions (5). Contemporary plant protection systems, on principle, should be economically efficient and eco-friendly (6). They should take advantage of all available pest-control methods while sus- taining natural self-regulation processes which occur in agricultural ecosystems.Although much progress is visible in the field of plant protection products, expressed, among others in the increasing selectivity, more rapid degradation as well as the use of integrated crop protection programs, we still need to monitor the environment, particularly in terms of protecting the beneficial entomofauna occurring there. Practical application of integrated plant protection solutions involves the use -to the highest extent possible -of all alternative, non...
