초록

Toxic symptoms of honeybees from the insecticide acephate, which frequently used in apple orchards, were
evaluated. We examined physical abnormalities from contact with residues on 1st, 3rd, and 5th day after acephate
or mixture of acephate with spreader-sticker and microbicide were sprayed on apple trees. The extended
tongue, unfolded wing hooks (detached fore and hind wings), and asymmetric three pair legs could be
observed as physical symptoms by toxicity. From contact with residual acephates (203.8±13.8 ppm) on 1 day
after spray, 28%~60% of total bees appeared to extend their tongues, which was significantly higher proportion
than untreated bees. 28%~33% of worker bees detached their fore and hind wings which were higher
than that of unsprayed bees, 10%. The bees showing asymmetric legs were so few on sprayed apple leaves
that it seemed to not affected by residual acephates. When honeybees contacted with residual acephates
(150.1±7.3 ppm) for 24 hours on three days after spray, the proportion of extended tongue was 42% in acephate
sprayed tree, which was significantly higher than that of bees in unsprayed trees. The abnormalities
of wings and legs from sprayed trees were not significantly different from unsprayed tree. The residual
acephate on five days after spray was 109.1±55.1 ppm, from which the mortalities of bees were below 5% and
proportions of abnormal tongue and wings were 1~6% and 3~11%, respectively. The proportion of
extended tongues among honeybees was related with residual chemical amount and bee mortality, and was
the most distinct physical symptom among three abnormal features observed.
