A planthopper is any insect in the infraorder Fulgoromorpha, [1] in the suborder Auchenorrhyncha, [2] a group exceeding 12,500 described species worldwide. The name comes from their remarkable resemblance to leaves and other plants of their environment and that they often "hop" for quick transportation in a similar way to that of grasshoppers.
These minute insects, colloquially known as hoppers, are plant feeders that suck plant sap from grass, shrubs, or trees. Their hind legs are modified for jumping, and are covered with hairs that facilitate the spreading of a secretion over their bodies that acts as a water repellent and carrier of pheromones . [ 1 ]
They can make a hissing sound when touched or otherwise disturbed, which can resemble the hissing of a bat. This sound is made by their wings pushing down, forcing the air out between their wings and back. They can be an agricultural pest affecting a wide range of crops because their larvae feed on plant roots and can weaken or kill the plants. [1]
The beetle is supine, on its back, in the pre-jump stage, and over ~2-3s it rotates its prothorax (foremost section) down to touch the ground in a bracing position. [4] In the takeoff phase the prothorax rotates rapidly upward in a "snap", launching the beetle off of the ground and ballistically into the air. [ 4 ]
Heavy infestations on cotton, okra, and sunflower make the leaves turn yellow, curl up and fall off. The insects also secrete honeydew, and sooty mould often grows on this, restricting the amount of light reaching the plant's photosynthetic surfaces and reducing the yield. [5] In many areas, this pest regularly occurs on cotton in epidemic ...
