3.2. Semi-field comparison of insecticide performance 2
In the second insecticide trial, adult mortality at 3 DAT was significantly higher than untreated in all insecticide treatments except the carbaryl treatment (Table 5). While mortality was lower in most treatments at 5 DAT, all the insecticide treatments except
acetamiprid and carbaryl had significantly higher mortality than the untreated. At 7 DAT, only the bifenthrin treatment had adult mortality above 50% and malathion 1113.8 g, acetamiprid, and carbaryl were not significantly different from the untreated. All the
insecticide treatments had significantly fewer larvae and pupae than the untreated at 3 DAT and 5 DAT, except the carbaryl treatment at 3 DAT. At 7 DAT, there were more larvae in the malathion treatments than the other chemical treatments, although none of
the treatments was significantly better than the untreated control.
