Abstract
Uptake and residues of hempa and thiotepa in Anthonomus grandis Boheman sterilized by vacuum fumigation, atmospheric fumigation, or vacuum dipping were determined. When comparable sterility was achieved in either type of fumigation treatment, the uptake of hempa was 10–100 times that of thiotepa. However, the uptake at atmospheric pressure was lower than that in the vacuum treatment. Thiotepa induced 99–100% sterility in all treatments but its uptake was lowest in the fumigation at atmospheric pressure. The uniformity of uptake by individual weevils was higher in the atmospheric fumigation than in the dipping. No residues of thiotepa were detected in treated weevils 4 days posttreatment but traces of hempa persisted for as long as 16 days posttreatment.
