The sub‐lethal effects of foliar fungicides on the mustard beetle, Phaedon cochleariae (F.) (Col., Chrysomelidae)

Abstract

The performance of the mustard beetle, Phaedon cochleariae (F.), treated orally and topically with a range of foliar fungicides was assessed using data on several life-history variables. For some compounds a significant effect on the insect's developmental period and/or fecundity was demonstrated. P. cochleariae larvae were shown to exhibit repellency towards host plants treated with some of the fungicides. Phaedon cochlearzae wurde oral und topikal mit einigen Blattfungiziden behandelt, urn eine Reihe von Entwicklungsparametern zu untersuchen. Fur einige Praparate konnte ein signifikanter Einfluf? auf 518 A . /. Cherry, N . W. Sotherton m d S. D. Wratten die Entwicklungszeit der Larven und/oder die Fekunditat nachgewiesen werden. Bei einigen Fungiziden zeigte sich eine repellente Wirkung auf P. cochleariae.

The effects of pesticides on species of non-target Heteroptera inhabiting cereal fields in southern England

“…For example the organophosphate fungicide pyrazophos possesses signiÐcant insecticidal properties to a range of non-target species.24h29 Sub-lethal doses of fungicides have also been shown to a †ect some invertebrates. 30 However, as important as this study may be in examining the impacts of fungicide use, it is perhaps also important in showing the potential diversity within this heteropteran group. All heteropteran species found occurred in the Ðeld boundary and 12 out of these 26 species were found only in this non-cropped habitat.…”

Impact of pesticides on the arthropofauna associated with potato (Solanum tuberosum) cultivation in Cusco-Peru

“…Bibliografía previa sugiere que el efecto del propineb sobre los artrópodos es leve dado que es un fungicida (Toledo, 2021). Sin embargo, se ha demostrado su impacto negativo sobre organismos no objetivos de suelo, las abejas y otros polinizadores (EFSA, 2016(EFSA, , 2020, así como sobre Phaedon cochleariae (F.) (Coleoptera: Chrysomelidae) (Cherry et al, 1992). Estos últimos resultados no concuerdan con lo obtenido en el presente estudio donde se observó que el tratamiento con mayor abundancia de individuos y un menor efecto negativo fue el propineb, mostrando un 45,82 % del total de individuos.…”
