“…In the same experiment, pirimicarb was highly toxic to larvae, with 83.3% corrected mortality, but development time and egg production was not affected. These results confirm the toxicity generally observed for hoverflies with pirimicarb in the laboratory (Jansen 1998;Hautier et al 2006) and in the field (Poehling and Dehne 1986;Storck-Weyhermuller 1989;Niehoff and Poehling 1995;Jansen 2001).…”

“…However, this product was particularly harmful to hoverfly larvae (Poehling and Dehne 1986;Storck-Weyhermuller 1989;Niehoff and Poehling 1995;Jansen 2000) and was therefore of limited interest for IPM where hoverflies must be preserved. In addition, several economically important aphid species, for example Aphis gossypii Glover and Myzus persicae Sulzer, have developed resistance against this insecticide (Field et al 1997;Barber et al 1999;McLoon and Herron 2009).…”

“…Aleochara bilineata is the indicative species for rove beetles in the registration of pesticides, and B. lampros was preferred to the larger carabid beetle species used in the past for assessing the side-effects of pesticides on this family, because of its greater sensitivity to pesticides (Hassan et al 1987(Hassan et al , 1988(Hassan et al , 1991. Episyrphus balteatus is the most common syrphid species found in arable crops in several central and north European countries (Niehoff and Poehling 1995;Jansen 2000). The larvae are aphid-specific predators that can be very effective in open fields and orchards (Chambers et al 1983;Chambers 1992;Wyss et al 1999;Freier et al 2007).…”

Side effects of flonicamide and pymetrozine on five aphid natural enemy species

The effects of flonicamide and pymetrozine, on inert and natural substrates, on the rove beetle Aleochara bilineata (Gyll.), the parasitic wasp Aphidius rhopalosiphi (DeStefani-Perez), the ladybird Adalia bipunctata (L.), the carabid beetle Bembidion lampros (Herbst), and the hoverfly Episyrphus balteatus (DeGeer) were assessed in the laboratory. Deltamethrin and pirimicarb were also tested as toxic reference compounds. The results indicated high selectivity of flonicamide and pymetrozine for all the species tested. No significant effects on B. lampros and A. bilineata were recorded for sand or on E. balteatus for plants. Pymetrozine on inert substrates had no effects on A. bipunctata larvae, whereas flonicamid was slightly toxic on glass plates but harmless on plants. Both compounds were toxic to adult A. rhopalosiphi on glass plates and on plants in the laboratory, but no effects were observed on plants treated in the field. In comparison, the toxic reference products were always more toxic. Compared with classical insecticides tested on the same species using similar methods, flonicamide and pymetrozine seem to be promising insecticides for aphid control in terms of selectivity for aphid antagonists.

“…Despite the broad spectrum toxicity of carbamates, many authors have demonstrated the selectivity of pirimicarb to several predatory insects such as Anthicidae, Chrysopidae and Coccinellidae (Angeli et al 2005;Bacci et al 2009;Cabral et al 2008). However, laboratory as well as field studies have proven the high toxicity of pirimicarb to syrphid larvae (Colignon et al 2003;Jansen 1998Jansen , 2000Niehoff and Poehling 1995). Jansen (1998) also demonstrated that all larvae of E. balteatus died 2 days after exposure to residues of pirimicarb on glass plates.…”

Side effects of pesticides on the larvae of the hoverfly Episyrphus balteatus in the laboratory

2010

The hoverfly Episyrphus balteatus (Degeer) is one of the most abundant predators of the cabbage aphid (Brevicoryne brassicae (L.)) in brussels sprouts in Belgium. In the current laboratory study, the toxicity of several insecticides applied at maximum recommended field rates was investigated on the larvae of E. balteatus. Two-to 3-day-old larvae were confined in glass petri dishes with dry residues of freshly applied insecticides. Their mortality was checked daily until adult emergence. Sub-lethal effects were investigated by assessing the reproductive performance of adult hoverflies, originating from the surviving larvae. Of the five compounds tested, only pirimicarb caused 100% larval mortality. The corrected mortality for spinosad was 60% and the adults obtained from the surviving larvae did not succeed in laying eggs. Therefore, pirimicarb and spinosad were rated "harmful" (International Organization for Biological and Integrated Control of Noxious Animals and Plants (IOBC) category 4) for the larvae of E. balteatus. In contrast, flonicamid, thiacloprid and spirotetramat yielded much lower mortality percentages. The hatching rate of hoverfly eggs treated with flonicamid was 25.6% vs 48.7% in the control. Hence, flonicamid was rated "slightly harmful" (IOBC category 2). The fertility of adults treated as larvae with thiacloprid or spirotetramat was not affected (IOBC category 1). These laboratory trials suggest that thiacloprid and spirotetramat can be used safely in integrated pest management programs to control the cabbage aphid. Pirimicarb, spinosad and flonicamid should be tested in semi-field and field situations to assess their toxicity under more realistic conditions

“…In the same study, no information about the toxicity of the products on coccinellids and syrphids was forthcoming because they were too scarce at the time of the treatment or because the sampling method was not appropriate. Effects of reduced doses of pirimicarb on hoverfly larvae were studied in a wheat field in Germany 22. Applied at rates of 100 and 50 g AI ha −1 , pirimicarb was harmful to syrphids and a certain degree of selectivity appeared only at an application rate of 25 g AI ha −1 .…”
