“…In spring, nymphs of the third instar migrate from the soil to the tree motivated by the increase of the temperature (Gobin et al 2008) which can explain the decrease of the abundance on soil. F. auricularia is an omnivorous species, feeding on a high variety of food items such as softfleshed fruit and plant material as well as a wide range of arthropods (Shaw and Wallis 2010), and is referred as an important generalist predator (Gobin et al 2008). In Crete, Neuenschwander et al (1983) observed F. aetolica Brunner predating B. oleae pupae in laboratory experiments.…”

Soil arthropods can provide ecosystem services, such as biological control of crop pests that spend part of their life cycle in the soil. This is the case of Bactrocera oleae (Rossi) (Diptera: Tephritidae), one of the most important pests of olives. The impact of edaphic arthropods on the abundance of B. oleae pupae was evaluated and their contribution for biological control of the pest was quantified. Exclusion and exposed boxes with B. oleae pupae were installed in olive groves in parallel with pitfall traps used for sampling arthropods and the percentage of pupae suppression was evaluated from January to May 2014. Forficulidae dominated the community during the winter period while Formicidae dominated in spring. Pupae suppression reached the maximum value in the beginning of spring and these results indicate that soil arthropods have strong impact in the decline of B. oleae pupae in olive groves.

“…Although effects on mobility were not always directly studied, spinosad side effects on this trait were observed for the predators C. carnea, 60 D. brevis, 66 Doru luteipes (Scudder) 119 and F. auricularia 70 and for the parasitoids Eiphosoma vitticolle Cresson 34 and H. didymator. 110,111 This effect is mostly due to direct intoxication by the pesticide, which results in a knockdown effect, trembling and lack of coordination in legs, wings, mandibles and palpus.…”

Spinosyn-based products, mostly spinosad, have been widely recommended by extension specialists and agribusiness companies; consequently, they have been used to control various pests in many different cropping systems. Following the worldwide adoption of spinosad-based products for integrated and organic farming, an increasing number of ecotoxicological studies have been published in the past 10 years. These studies are primarily related to the risk assessment of spinosad towards beneficial arthropods. This review takes into account recent data with the aim of (i) highlighting potentially adverse effects of spinosyns on beneficial arthropods (and hence on ecosystem services that they provide in agroecosystems), (ii) clarifying the range of methods used to address spinosyn side effects on biocontrol agents and pollinators in order to provide new insights for the development of more accurate bioassays, (iii) identifying pitfalls when analysing laboratory results to assess field risks and (iv) gaining increasing knowledge on side effects when using spinosad for integrated pest management (IPM) programmes and organic farming. For the first time, a thorough review of possible risks of spinosad and novel spinosyns (such as spinetoram) to beneficial arthropods (notably natural enemies and pollinators) is provided. The acute lethal effect and multiple sublethal effects have been identified in almost all arthropod groups studied. This review will help to optimise the future use of spinosad and new spinosyns in IPM programmes and for organic farming, notably by preventing the possible side effects of spinosyns on beneficial arthropods.

“…Adult coccinellids are also mobile, but they can also fly out of the orchard, avoiding toxic exposure. In addition, most studies have probed no lethal effect of chlorantraniliprole regarding adult predators (Preetha et al 2010;Shaw and Wallis 2010;Campos et al 2011;Gradish et al 2011). Novaluron is a chitin synthesis inhibitor, and it only affects immature stages (Cutler and Scott-Dupree 2007;Trostanetsky and Kostyukovsky 2008).…”

Differential sensitivity of an invasive and an indigenous ladybeetle to two reduced‐risk insecticides

The invasive multicoloured Asian lady beetle, Harmonia axyridis (Pallas), and the indigenous twelve spotted lady beetle, Coleomegilla maculata DeGeer (Col., Coccinellidae), are two important generalist predators commonly found in apple orchards in Quebec, Canada. Both species are exposed to two reduced-risk insecticides, recently adopted to control codling moth, Cydia pomonella (L.) (Lep., Tortricidae) in south-eastern Canada. Chlorantraniliprole (Altacor â 35 WG), an anthranilic diamide insecticide, causes paralyses of the muscle cells by interfering with the insect ryanodine receptors, whereas novaluron (Rimon â EC 10), a benzoylphenyl urea, inhibits the chitin synthesis. The aim of this study was to compare the sensitivity of both the invasive ladybeetle H. axyridis and the indigenous C. maculata to reduced-risk insecticides through the assessment of lethal effect on eggs and larvae following topical contact, ingestion of treated prey and exposure to fresh residues, at field rates (50.75 g a.i./ha chlorantraniliprole and 100 g a.i./ha novaluron) in laboratory conditions. Eggs of both species were not affected. Following 6 days of residual contact, chlorantraniliprole and novaluron caused more than 98% mortality to larvae of both ladybeetle species. In topical contact and ingestion trials, chlorantraniliprole caused less than 18% mortality to larvae of the two species after 6 days following exposure. Novaluron had a drastically different impact on the two predators. It did not affect the indigenous C. maculata, whereas it killed 91% and 96% of H. axyridis individuals after 6 days, respectively, following topical contact and ingestion. These results illustrate a differential sensitivity to novaluron between two relatively close species (subfamily Coccinellinae), a potential impact on the invasion process by H. axyridis, and consequently on the ladybeetle assemblage in the field.
