What are the natural enemies of flies, and what are they most afraid of?

Flies harm humans by carrying and spreading a variety of pathogenic microorganisms. Do you know what the natural enemies of flies are? Besides fly-killing gadgets such as mosquito killers, fly swatters and sticky fly paper, do you know what else flies are afraid of? Let's take a look below at these things that flies fear!

What are the natural enemies of flies?

In the biological world, the natural enemies of flies fall into three categories: predatory natural enemies, parasitic natural enemies and microbial natural enemies:

1. Predatory natural enemies: including frogs, dragonflies, spiders, mantises, ants, lizards, geckos, robber flies and birds, etc. Chicken manure is the breeding material for house flies and stable flies, but it often contains the ferocious Macrocheles mites and earwigs, which prey on fly eggs and fly maggots in the manure.

2. Parasitic natural enemies: such as ichneumon wasps, chalcid wasps and other parasitic wasps, which often lay their eggs inside fly maggots or pupae, and after hatching, the larvae feed on the fly maggots and fly pupae. Some people have found that among the flesh fly pupae dug up in spring, 60.4% died after being attacked by parasitic wasps.

3. Microbial natural enemies: Japanese scholars have found that Bacillus moritai can inhibit fly breeding.

What are flies most afraid of?What plants are flies afraid of?

Some plants have a special fragrance or scent that is harmless to humans, but mosquitoes, cockroaches, flies and other pests will avoid it as soon as they smell it. Some of these special fragrances or scents can also inhibit or kill bacteria and viruses. These plants include: tuberose, pyrethrum, wild chrysanthemum, four o'clock flower, lemon, crape myrtle, jasmine, orchid, lilac, Atractylodes lancea, cornflower, dandelion, mint, etc.

1. Night-blooming jasmine: also known as night jessamine, native to tropical America. Its leaves are heart-shaped with soft hairs along the edges. Between summer and autumn, clusters of small yellow-green bell-shaped flowers bloom in the leaf axils. When the moon rises above the treetops, it gives off waves of delicate fragrance. This scent frightens mosquitoes and makes it an excellent mosquito repellent.

2. Lavender: a small blue-purple flower native to the Mediterranean, with a flower shape like a wheat spike, usually blooming in June. Lavender itself has an insecticidal effect, which is why people make it into sachets and put them in wardrobes, and some also place them in bedrooms, to repel mosquitoes.

3. Pitcher plant: a carnivorous plant and a master mosquito catcher.

4. Orange jasmine: orange jasmine is a small evergreen shrub with a corymb-like shape, small glossy leaves, dense white flowers and red berries. Touching its leaves gives off a strong sweet fragrance, and its mosquito-repelling effect is very good.

Characteristics:

1. Looking at their individuals: among a group, the smaller individuals are generally male, and the larger individuals are generally female;

2. Look at their abdomens to tell male from female: the abdomen of a male fly is small and flat, while the abdomen of a female fly is large and round;

3. Look at their rear ends to tell the female: the rear end of a male fly is round, while the rear end of a female fly is pointed.

Activity characteristics:

1. Flies are insects that are frequently active during the day and have an obvious phototaxis. At night they rest motionless. Their activity and resting places depend on the fly species, season, temperature and region.

2. In some seasons, stable flies, summer side flies and market flies also invade homes. Chrysomya megacephala, Lucilia sericata, blue bottle flies, Calliphora flies, flesh flies, etc. mainly live and rest outdoors.

3. The activity of flies is greatly affected by temperature. At 4-7°C they can only crawl, at 10-15°C they can fly, only above 20°C can they feed, mate and lay eggs, they are especially active at 30-35°C, they stop activity at 35-40°C due to overheating, and they die at 45-47°C.

4. Flies are good at flying. Their flight speed can reach 6-8 km per hour, and the maximum flight distance per day and night is 8-18 km.
