Abstract

By injecting fenitrothion into fluid in leaves of pitcher plants, Sarracenia purpurea L., it was determined that the mosquito, Wyeomyia smithii (Coquillett), and the midge, Metriocnemus knabi (Coquillett), are under some risk from fenitrothion forest sprays at the rate of 210 g AI/ha. Wyeomyia smithii is slightly more susceptible than is M. knabi. Other leaf inhabitants, mites and rotifers, were not affected by initial concentrations of fenitrothion in the fluid (up to 9.6 μg/L) that did affect the mosquito and the midge.

Résumé

L’injection de fénitrothion dans le fluide de feuilles de la sarracénie pourpre, Sarracenia purpurea L., a indiqué que le moustique Wyeomyia smithii (Coquillett) et le moucheron Metriocnemus knabi (Coquillett) sont vulnérables aux épandages de fénitrothion en forêt à la dose de 210 g d’ingrédient actif/ha. Wyeomyia smithii s’est révélé un peu plus sensible que M. knabi. D’autres espèces présentes, des acariens et des rotifères, n’étaient pas sensibles aux concentrations initiales de fénitrothion, jusqu’à 9,6 μg/L dans le fluide, qui avait un effet sur le moustique et le moucheron.
