Abstract:Responses of Aedes albopictus (Skuse)females to the organic infusions from several plants were evaluated with sticky ovi_traps in the field. No significant difference in the mean number of A. albopictus collected was found between the sticky ovitrap baited with the organic infusions from camphor leaf, boxtree leaf, green bristle grass leaf, Bermuda grass, Magnolia grandiflora leaf, and bamboo leaf, and that with tap water. The organic infusions from bamboo leaf, Magnolia grandiflora leaf, green bristle grass and Bermuda grass fermented for 21 days or 30 days or 45 days showed no significant difference. When eggs collecting traps were used, significant differences were found between the organic infusions and the dilutions from bamboo leaf, Magnolia grandiflora leaf, green bristle grass and Bermuda grass, and that from tap water. There was no significant difference among tap water, standing water outdoors, and larvae rearing water.
