在树洞生态系统中，三角伊蚊的幼虫以分解落叶的微生物为食。扫描电子显微图显示，蚊子的浏览大大减少了腐叶上的微生物丰度。实验表明，幼虫密度增加会降低幼虫存活率、化蛹率、蛹生物量和总产量。快速分解的凋落叶（糖枫）比缓慢分解的凋落叶（山毛榉和黑橡树）更能支持蚊子的生长。蚊虫产量明显受幼虫密度和碎屑动态的调节。
Larvae of A. triseriatus mosquitoes feed on microbes that decompose leaf litter in tree-hole ecosystems. Scanning electron micrographs indicate that browsing by mosquitoes substantially reduces microbial abundance on decaying leaves. Experiments using laboratory microcosms demonstrate that increased larval density decreases larval survivorship, pupation rates, pupal biomass and total yield. Rapidly decomposing leaf litter (sugar maple) supports more mosquito growth than slowly decomposing litter (beech and black oak). Mosquito yield was apparently regulated by larval density and detrital dynamics.
