The chemical compounds norbornanetetraacetate (1b),
cyclooctane-1,2,5,6-tetraacetate (2b), and lactone 3 showed
fumigant toxicity against adults of Sitophilus granarius
(Coleoptera: Curculionidae). The P-value tests were carried
out to determine the statistical significance of dose and time
combinations against the insect. Norbornanetetraacetate (1b)
was the most toxic of the three compounds tested in 3 μL
(1 μL/L air) within the first 24 h after application. The same
level of toxicity was obtained with cyclooctane-1,2,5,6-tetraacetate
(2b) in 3 μL at 48 h. On the other hand, lactone
3 was the most toxic of the three compounds tested in 3 μL
(1 μL/L air) at 72 h. In 9 μL (3 μL/L air), norbornanetetraacetate
(1b) was the most toxic of the three compounds
tested on adult S. granarius up to 48 h. Norbornanetetraacetate
(1b) was more toxic than lactone 3 and cyclooctane-
1,2,5,6-tetraacetate (2b) at 6-48 h in 9 μL (3 μL/L air),
and as toxic as lactone 3 at 72 h. In general, norbornanetetraacetate
(1b) is more toxic than cyclooctane-1,2, 5,6-
tetraacetate (2b) and lactone 3 at all doses and exposure
times against adult S. granarius.
