However, some thrips, including rose thrips, onion thrips, and western flower thrips, damage plants. They can weaken vegetables and flowers and even spread plant diseases . What Do Thrips Look Like?
Thrips simplex is a tiny insect, measuring 2 mm (0.08 in) long, with a long slender brownish-black body with a pale band at the base of the wings. The larvae are wingless and yellow or orange. These thrips live hidden inside the leaf and flower sheaths of their host plants where they suck sap, usually occurring in groups.
The flowers are damaged causing discolouration, distortion and stunting, and may die. Secondary damage is caused by the viruses that can be transmitted between plants. [1] The insect can be a vector of tomato spotted wilt virus, which causes a serious disease of groundnuts and other crops. [7]
The generic and English name thrips is a direct transliteration of the Ancient Greek word θρίψ, thrips, meaning "woodworm". [4] Like some other animal-names (such as sheep, deer, and moose) in English the word "thrips" expresses both the singular and plural, so there may be many thrips or a single thrips. Other common names for thrips ...
To protect their eggs, thrips insert them into various types of plant tissue - eggs can be found in the stems, leaves, or flowers of plants. [8] Thrips hatch in 2–3 days and complete their lifecycle in 20–30 days. [2] Adult thrips feed on the flower bud, stem, and leaf parts of the plant. [8]
Injury in plants is damage caused by other organisms or by the non-living (abiotic) environment to plants. Animals that commonly cause injury to plants include insects, mites, nematodes, and herbivorous mammals; damage may also be caused by plant pathogens including fungi, bacteria, and viruses. Abiotic factors that can damage plants include ...
Western Flower Thrips are extremely hard to remove from their host plants, as they often dig themselves deep into blossoms, buds and other areas hard to reach with insecticides. [9] So, even if plants are sprayed regularly with insecticide, INSV and other insect vectored viruses can not always be ruled out when forming diagnosis.
F. tritici inhabits blossom, such as dandelion flowers. [3] They can directly damage plants, grasses and trees, in addition to commercial crops, [3] and as a vector for tospoviruses, a form of plant virus, it particularly affects small fruit production in the United States, including strawberries, grapes, blueberries and blackberries.
