The lace bug, Corythucha gossypii (Fabricius) is a serious pest affecting over 24 wild and commercially important plant species of the families Annonaceae, Passiflorcae, Caricaceae, Euphorbiaceae, and Solanaceae. Thus far, commercial insecticides, such as 0.1% Dimethoate and 0.1% Imidacloprid have s...

The lace bug, Corythucha gossypii (Fabricius) is a serious pest affecting over 24 wild and commercially important plant species of the families Annonaceae, Passiflorcae, Caricaceae, Euphorbiaceae, and Solanaceae. Thus far, commercial insecticides, such as 0.1% Dimethoate and 0.1% Imidacloprid have shown effectiveness against this insect, but no botanical pesticides are available to control this bug. In the present study, a Rollinia mucosa (Jacq.) Baillon ethanol extractwas evaluated as a biological control agent against the lace bug. Through a toxicity assay involving Artemia salina, the median lethal concentration (LC50) of a raw ethanol extract of R. mucosa seeds was determined, as well as that of its Acetogenin (F1) and Alkaloid (F2) fractions; these LC50 were 0.184, 0.082, and 0.0493 g/mL, respectively.
