Performance of Aedes albopictus and A. riversi Larvae (Diptera: Culicidae) in Waters That Contain Tannic Acid and Decaying Leaves: Is the Treehole Species Better Adapted to Treehole Water?

摘要: In northern Kyushu, Aedes albopictus (Skuse) exploit various natural and artificial containers; A. riversi Bohart & Ingram treeholes exclusively. Development, growth, survival of larval were compared in water containing commercial tannic acid, decaying leaves Camellia japonica L. Elaeocarpus sylvestris (Lour.) Poir., treehole collected the field. period was prolonged adult size increased both mosquito species. Mortality with an increase acid concentration, and, particular, showed higher mortality than at 100 mg/liter. leaves, which dark, acidic, contained abundant tannin-lignin, longer smaller species diet but no leaf litter. This difference partly a result low nutritional value leaves. Larval high many E. because acidity or tannin-lignin content. diet, generally performed better tap (control), consistent detected their responses to water. general, performance simulated larvae, species, not that , used infrequently. Habitat differences larvae may be related directly differential adaptation particular conditions.
