They are typically harmless to healthy plants - and humans - but can inflict extensive damage to seedlings; their presence can indicate more serious problems. In houseplants , the presence of sciarids may indicate overwatering; they may be feeding on roots that have been immersed in water too long and are thus rotting, or the gnats may be ...
Some plants prefer flowing water, while others, such as lotuses, prefer stagnant water. Various anaerobic bacteria are commonly found in stagnant water. [ 4 ] For this reason, pools of stagnant water have historically been used in processing hemp and some other fiber crops , as well as linden bark used for making bast shoes .
The Food Defect Action Levels: Levels of Natural or Unavoidable Defects in Foods That Present No Health Hazards for Humans is a publication of the United States Food and Drug Administration's Center for Food Safety and Applied Nutrition [1] detailing acceptable levels of food contamination from sources such as maggots, thrips, insect fragments, "foreign matter", mold, rodent hairs, and insect ...

Rhagoletis mendax is a species of tephritid fruit fly known by the common name blueberry maggot. The blueberry maggot is closely related to the apple maggot (R. pomonella), a larger fruit fly in the same genus. It is a major pest of plant species in the Ericaceae family, such as blueberry, cranberry, and huckleberry. The larva is 5 to 8 mm long ...
The larvae damage bulbs of onions, garlic, chives, shallots, leeks, and flowering plants. The first generation of larvae is the most harmful because it extends over a long period owing to the females' longevity and occurs when the host plants are small. Seedlings of onion and leek can be severely affected as can thinned-out onions and shallots. [3]
Many plants, such as peanuts, produce compounds that are only dangerous to people who have developed an allergic reaction to them, and with a few exceptions, those plants are not included here (see list of allergens instead). Despite the wide variety of plants considered poisonous, human fatalities caused by poisonous plants – especially ...
Adult non-biting gnats do not damage plants but are considered a nuisance. Usually, larvae do not cause serious plant damage, but when present in large numbers can stunt the plant growth and damage its roots. [6] To prevent gnats from spreading, measures have to be taken to target immature stages of development of the species.
