Among the many parasitic adversities that can affect our plants, the Tripid is one of the most harmful insects that can happen to us.
Thrips are a family of plant insects of the order Thysanoptera which has more than five thousand different species all over the globe.
The thrips, scientific name Thripidae, are many small insects with an elongated body, about 1.5 mm, usually of a color that is close to black (but may vary and depending on species).
The dimensions of the larvae of the thrips are even smaller, in fact they can reach at most half a millimeter about half of the adults, they have a lighter color and are without wings.
In the adult individuals the wings are long and thin, crossed by a single rib, jagged at the edges. In resting position, seen the reduced size of the insect, they are not much evident.
How To Recognize A Thrips Infestation?
The Thrips are phytomatous insects which nourish of the sap of the leaves, the flowers, the fruits and the young shoots of the infested plant.
When a plant is infested with thrips, it has distinctive, recognisable signs that can be traced back to this parasite.
Thrips hide by grouping together in the lower parts of the leaves or in the youngest parts of the plants, the shoots.
Thrips infested plants have small reddish-brown spots on the leaves, which tend to become darker as the infestation worsens.
The fruits of the plants, if affected, will show deformities and loss of consistency. The flowers dry up or fade.
How To Detect This Parasite
Although thrips are many small and nest in shoots, we can identify these parasites by detaching some leaves or buds, shaking the latter on a clear sheet, we will notice that many of these parasites will fall and will be well recognizable.
What Makes The Thrips So Harmful?
In addition to sucking the sap from the leaves, fruits or buds, causing it to deteriorate, the thrips with its saliva can also transmit many diseases to the plant.
