“…Sulfoxaflor was slightly toxic (IOBC 2) but pesticide formulation is pertinent for compatibility. In contrast with our results, an experimental formulation of sulfoxaflor (60 mg a.i./L, 11.4% SC; Dow Agrosciences Ibérica S.A.) was compatible with adults of this predatory mite in the laboratory (Fernández et al, 2017). In agreement with literature, two applications of the rest of the tested pesticides were compatible with A. swirskii.…”

“…A short duration of the pesticide harmful activity is important for NE safety. As such, emamectin benzoate (IOBC category A in the persistence scale; Fernández et al, 2017) and spirotetramat were compatible after two applications in our trial . However, another formulation of emamectin benzoate has been rated as slightly harmful or harmful , probably because phytoseiid community level interactions, different in every field trial, play a role (Bakker & Jacas, 1995).…”

“…The predatory mite A. swirskii is rather compatible with pesticides under laboratory (flubendiamide, methoxyfenozide, spiromesifen, spirotetramat, metaflumizone) (Gradish et al, 2011;Fernández et al, 2017) or field conditions (methoxyfenozide, flonicamid, emamectin benzoate) (Colomer et al, 2011;Amor et al, 2012). Sulfoxaflor was slightly toxic (IOBC 2) but pesticide formulation is pertinent for compatibility.…”

“…Therefore, despite the ability of NE to control several pests with simultaneous outbreaks in the crop, chemical treatments are often sometimes needed to maintain key and secondary pest populations under economic thresholds and the ascertaining of their compatibility is crucial for success. Thus, toxicity and sublethal effects of pesticides on NE of horticultural pests has been extensively studied under laboratory or semifield conditions (Amor et al, 2012;Bengochea et al, 2012;Abraham et al, 2013;Döker et al, 2014;Garzón et al, 2015;Maia et al, 2016;Wanumen et al, 2016;De Bortoli et al, 2017;Fernández et al, 2017, Madbouni et al, 2017. In general, much less information is available on the compatibility of novel pesticides and NE inside commercial greenhouses.…”

Successful integrated pest management in protected crops implies an evaluation of the compatibility of pesticides and natural enemies (NE), as control strategies that only rely on one tactic can fail when pest populations exceed NE activity or pests become resistant to pesticides. Nowadays in Almería (Spain), growers release NE prior to transplanting or early in the crop cycle to favor their settlement before pest arrival because this improves biocontrol efficacy, although it extends pesticide exposure periods. The purpose of this research was to evaluate the compatibility of two applications of pesticides with key NE in 2‐year trials inside tomato and sweet pepper commercial greenhouses: Nesidiocoris tenuis (Reuter) (Hemiptera: Miridae), Orius laevigatus (Say) (Hemiptera: Anthocoridae) and Amblyseius swirskii (Athias‐Henriot) (Acari: Phytoseiidae). In tomato, flubendiamide and chlorantraniliprole (IOBC category 1) were compatible with N. tenuis, but chlorpyrifos‐methyl and spinosad (IOBC categories 2–3), which effectively reduced Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) density, compromised its predatory activity. In sweet pepper, chlorantraniliprole (IOBC category 1) was the only pesticide compatible with O. laevigatus while chlorantraniliprole, emamectin benzoate, spirotetramat and pymetrozine were harmless (IOBC category 1) to Amblyseius swirskii, and sulfoxaflor slightly harmful (IOBC category 2) to this phytoseiid predator.

“…In recent years, the increasing number of agricultural producers consciously alerted for a sustainable use of pesticides have contributed to a growing implementation of Integrated Pest Management (IPM) programs (Kenis et al, 2017;Stenberg, 2017), becoming mandatory in all European Union (EU) countries (OJEU 2009) since the EU directive 2009/128/EC, on sustainable use of pesticides, came into force (Fernandez et al, 2017). According to this directive, it is essential to understand the risks of pesticides and adopt pest control strategies that include more effective and selective substances (Cooper and Dobson, 2007;Damalas, 2009).…”

BACKGROUND: Biological control in conventional agroecosystems involves the integration of chemical and conservation tactics, requiring knowledge of pesticide non-target effects on key natural enemies. Even for natural enemy groups such as predatory mites (Acari: Phytoseiidae), where pesticide non-target effects have been thoroughly examined, there may be significant differences in species susceptibility to specific active ingredients, including newer selective products. Using bioassays, we examined lethal (female mortality) and sublethal (fecundity, egg hatch, larval survival) effects of ten miticides on a spider mite pest (Tetranychus urticae) and three insectary-purchased predatory mites (Phytoseiulus persimilis, Neoseiulus californicus, and N. fallacis) commonly used for its management. Susceptibility of field-collected and insectary-reared populations of P. persimilis was also compared. Cumulative impacts on production of larvae by treated female spider mites and predators were compared to create a metric that simultaneously accounted for miticide efficacy and selectivity.Results: Bifenthrin was the least selective, as it caused acute toxicity to all predators and had little efficacy against T. urticae. Hexythiazox and cyflumetofen were the most selectively favorable. Phytoseiulus persimilis populations were similar in which miticides they were sensitive to, although the insectary-purchased population was generally more sensitive.Conclusions: All products, including those considered selective (cyflumetofen, bifenazate, acequinocyl) had non-target effects on at least one species of predator tested. This work emphasizes that there is high variability in selectivity among species, highlighting the need to examine key natural enemies individually when creating management programs. Published 2020.
