Comparison of the effects of oxamyl on the mortality of adults and larvae after 1 and 24 h of exposure to direct spray or contact/ingestion (under laboratory conditions) expressed as percentage of the control mortality of adults and larvae after exposure to distilled water (Control). Each point is the mean of mortality percentage ± SEM for 3 replicates.
RPW treated in the laboratory by direct spray with oxamyl, 1 h after treatment (top) and 24 h after treatment (bottom).
Adult emerging from pupae after treatment with oxamyl in the field (a foliar treatment).
Comparison of the effects of oxamyl on the mortality of adult and larvae during 7 days of investigation after a foliar application and adding with irrigation water (under field conditions) expressed as percentage mortality after exposure to well water (Control). Each point is the mean of mortality percentage ± SEM but in most cases the error bars are smaller than the symbols used. The lines were fitted using a non-linear regression in Graph Pad Prism 7 with the maximum plateau being 100% and the minimum being 0%. Each curve indicates the mortality of adult and larvae after exposure to oxamyl by a foliar application and adding with irrigation water (under field conditions) compared with control.
RPW treated with oxamyl on the date palm tree. The top left, top right, bottom left and bottom right pictures were taken after 3, 4, 5 or 6 days, respectively, after direct spray treatment.
