Wasp and Scale Insects Help Control Giant Reed. An arundo gall wasp deposits eggs into the main stem of a giant reed. (Image by USDA/ARS) The release of tiny insects to combat the invasive weed giant reed is paying off, according to a recent U.S. Department of Agriculture (USDA) study.
For this reason, insect larvae often cause far more damage to stored crops and textiles than adult insects. Insect larvae generally have a thinner exoskeleton than the adult; many are white and soft. The characteristic fly larvae are maggots, often developing in decaying plant or animal material.Mosquito larvae are the familiar aquatic wrigglers; they breathe air and are killed by a thin film of oil on the water that prevents contact with air.or this reason, insect larvae often cause far more damage to stored crops and textiles than adult insects.
