Assessing the susceptibility and efficacy of traditional neurotoxic (pyrethroid) and new-generation insecticides (chlorfenapyr, clothianidin, and pyriproxyfen), on wild pyrethroid-resistant populations of Anopheles gambiae from southern Benin

Table 2 Oviposition and oviposition inhibition rates of a susceptible laboratory colony of Anopheles gambiae s.l. (Kisumu strain) and wild Anopheles gambiae s.l. from Ifangni after exposure to 100 μg pyriproxyfen (PPF) and acetone (control) using the WHO bottle bioassay

Strain	Test	Chambers tested at 96 h	Percentage (%) of eggs laid at different time intervals [95% confidence interval {CI}]				Oviposition inhibition (%) [95% CI]
