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 ]
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.
Sphaerocoris annulus can reach a length of about 15 millimetres (0.59 in). [2] [3] The basic color is green, with eleven ring-shaped spots on the scutellum.The colors and the design of these bugs represent a warning to predators.
Orius spp. (minute pirate bugs) are predatory insects that are commonly used as a biological control in greenhouses and against E. decipiens. This form of control is typically unsuccessful in significantly controlling the green leafhopper populations as the leafhopper will hop away when disturbed and are capable of flying, making the chance of ...
Siphanta acuta is a species of planthopper in the family Flatidae; this species is native to Australia, but is now found in various other parts of the world.About 10 mm long, they resemble small leaves and are generally found in trees.
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 ...
They can be generally referred to as phasmatodeans, phasmids, or ghost insects, with phasmids in the family Phylliidae called leaf insects, leaf-bugs, walking leaves, or bug leaves. The group's name is derived from the Ancient Greek φάσμα phasma , meaning an apparition or phantom , referring to their resemblance to vegetation while in fact ...
Treehoppers have specialized muscles in the hind femora that unfurl to generate sufficient force to jump. [ 3 ] It had been suggested that the pronotal "helmet" could be serial homologues of insect wings, [ 4 ] but this interpretation has been refuted by several later studies, such as Mikó et al. (2012) and Yoshizawa (2012).
