Aphids are tiny oval-shaped insects that can be of any color, although they’re most commonly found in light-green to red color. They are usually found sticking to stems and undersides of leaves as colonies. Thrips, on the other hand, are more slender-shaped winged insects and are typically yellow or black-colored.
The development of thrips is unique. Each larval stage ends with the molt, or shedding of the exoskeleton, or hard outer covering. … In thrips, the antennae are very small, and the developing wings can clearly be seen on the outside of the pupa.
Aphids are soft-bodied, sucking insects that are sometimes called plant lice. They feed on plant sap and subsequently excrete a sugary substance (called honeydew) that can attract ants as well as support the growth of a saprophytic fungus called sooty mold.
Thrips are the only insects that have asymmetrical mouthparts. Of the three feeding stylets, two are derived from the maxillae and one is derived from the left mandible.
Thrips damage includes streaks, silvery speckling and small white patches. If you see any signs of damage, discard the infested plants by securely bagging and putting in the trash—do not put them in your compost pile. Use blue sticky traps: Use these traps are helpful for controlling adult thrips.
CLEAR INDICATORS: Tiny black specks on leaves and buds, leaf stippling. There are other insects that leave black specs on plants, so use a magnifying glass to confirm that your pest is a thrips. An easy way to look for thrips is to bang a branch or leaves over a sheet of white paper.
Adult thrips are needle-like in appearance (long and slender); less than 1 mm long; have setae on the edges of two pair of wings; and are white, yellow, dark brown, black, or translucent (University of California Agriculture and Natural Resources, 2017).
Adult and larval thrips can bite people (Bailey 1936) and cause welts and rashes or other dermal reactions (Lewis 1973). … It is helpful to educate people to the fact that some thrips species can bite humans. Such biting does not result in any known disease transmission but skin irritations are known to occur.
The thrips family is very large; there are many species of thrips. But don’t panic: most of them are harmless. … Thrips sucks plant juices from the upper leaf and/or flower cells, resulting in the characteristic silver-grey spots and brown dots. This can lead to considerable damage.
Like all insects, an ant’s body is divided into three main parts: the head, the thorax, and the abdomen. Ants have a hard, waterproof exoskeleton, which is made of a material called chitin. They are exceptionally strong for their size: they can lift 10 times their own weight!
Most aphids are born pregnant and beget females without wastrel males. These parthenogenetic oocytes result from a modified meiosis that skips the reduction division, maintaining diploidy and heterozygosity. Embryos complete development within the mother’s ovary one after another, in assembly line fashion.
Spider mites are not spiders. They’re actually teeny tiny arachnids that feed on the juice of plant and tree leaves.
These pests sometimes bite humans in search of moisture on the skin and will also cause slight irritation to the toes and feet should one walk through grass barefoot. Thrip bites only cause minor irritation and do not usually have long-term effects.
Thrips range in size from 1 / 50- to 1 / 25-inches long and often have a white, dark yellow, or brown color. Adult thrips have silvery wings but they are not naturally for flying very far. They use their wings to glide between leaves in search of more food and a place to lay their eggs and rear their larvae.
Damage. Extremely active, thrips feed in large groups. They leap or fly away when disturbed.
Black, varnish-like specks of excrement are a distinguishing feature of thrips activity. Feces may remain on leaves or fruit long after thrips have left. Thrips are poor fliers; damage may first appear in one location then slowly spread over the plant.
About 1/16″ long, thrips can move quite quickly for their size. Many gardeners report thrips as a small “worm with legs”. Larvae and adults look similar, but adults have wings and can fly.
Ladybugs are a natural predator of pests like aphids and thrips. … Both the adults and the larvae find and devour aphids, but the adults don’t have a very big appetite, so growers need to use more adults to achieve the same level of control as they would if using larvae.
Adult western flower thrips are approximately 1-2 mm in length and generally yellowish-brown in colour. Identification to the species level is difficult (especially among western flower thrips, eastern flower thrips and onion thrips) because they are so small and their colour varies.
Damage to the whole plant With a magnifying glass, you can see the small insects crawling around. Shake a leaf over a sheet of white paper. Tiny specks will fall down on it. If they’re a bit oval and long, shaped like a small grain of rice, they’re thrips!

The biting and sucking of thrips is responsible for the transmission of plant disease including many types of fungus and virus. Thrips will readily sting people and pets. Though not generally identified as a biting pest, thrips are readily attracted to people.
Thrips are attracted to the colors yellow and blue, so yellow and blue sticky cards are an effective way to monitor populations (Figure 11). The cards should be placed among plants just above the canopy level so that the insects are caught during flight. Blue or white water pan traps can also be used for monitoring.
Thrips can bite humans, but they are not known to spread diseases. In most cases, thrips bites only cause temporary, minor itching and skin irritation.
What Are Thrips? Thrips are long, slender insects that are rarely over a quarter-inch in length in their adult form. Yellow, black, or brown are common colors for adults, and the larval stages tend to be yellow or green. These insects fall into the Thysanoptera order of insects.
As you now know, thrips leave their excrement on the plants. These tiny black specks make them unappealing to eat. Although the internal parts might still be intact and edible, the outer layer would be extremely uninviting to customers.
Several species of thrips are a major problem in greenhouse horticulture. … There are more than 6,000 known species. Most are harmless, some are predators, and fewer than 20 species can cause problems in agriculture and horticulture. Thrips are small insects (0.5-14 mm), with the largest species found in the tropics.
Wings: Flying termites have 2 pairs of wings that are the same size and shape, and are twice as long as their body.
Besides of sugary foods, ants also eat protein to grow. High protein in foods like peanut butter, meat and egg will surely attract a group of ants to come. They are also attracted to cooking grease which commonly is found in kitchen surfaces and cooking utensils.
Abdomen The abdomen contains the heart and stomach. Ants share their food with others, by spitting it up! Worker ants of some species carry a stinger on the back of their abdomen used to protect themselves or to fight other ants. In the front part of the abdomen, near the “waist” of the ant, you can see the petiole.
Insects are no slouches when it comes to reproduction and the African driver ant, which can produce 3 to 4 million eggs every 25 days, is thought to be the most generous of all.
In fact, ants farm aphids because, in return, they get a huge supply of their favorite sticky sweet treat. As aphids feed, they produce a sticky substance called honeydew, and ants simply cannot resist it.
Aphids are sucking insects that are common on both outdoor and indoor plants. They feed on the sap of plants and secrete a substance called honeydew. This sticky resin is a favorite food of ants, who actually “milk” the aphids for it by stroking their abdomen.
Unlike other insect bites or stings that form a single lump on the skin with a noticeable puncture site, mite bites induce skin rashes on the legs, arms, and trunk. General signs to look for include: small, hard bumps on the skin. red patches of skin.
The gnathosoma is not a true head, like that of an insect, in that it possesses neither eyes nor antennae and does not contain the brain. (Most mites have no eyes at all, but those that do bear them on the idiosoma. The brain is situated anterior to the stomach in the idiosoma.)
White mites come in different colors but there is a species known as the two-spotted spider mite, which is white. … White Mites are considered harmless because they don’t bite or cause any structural damage. But in truth, they are harmful because they shed long hairs frequently.
After 6 h, the numbers of thrips attracted to the white, deep sky blue, powder blue, and medium orchid cards all increased, except for the powder blue cards (Fig. 2).
