Hemiptera is an order of insects, commonly called true bugs, comprising over 80,000 species within groups such as the cicadas, aphids, planthoppers, leafhoppers, assassin bugs, bed bugs, and shield bugs. They range in size from 1 mm (0.04 in) to around 15 cm (6 in), and share a common arrangement of piercing-sucking mouthparts. The name "true bugs" is often limited to the suborder Heteroptera.
Whiteflies are Hemipterans that typically feed on the undersides of plant leaves. They comprise the family Aleyrodidae, the only family in the superfamily Aleyrodoidea. More than 1550 species have been described.
The glassy-winged sharpshooter is a large leafhopper, similar to other species of sharpshooter.
The silverleaf whitefly is one of several species of whitefly that are currently important agricultural pests. A review in 2011 concluded that the silverleaf whitefly is actually a species complex containing at least 40 morphologically indistinguishable species.
A leafhopper is the common name for any species from the family Cicadellidae. 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. They undergo a partial metamorphosis, and have various host associations, varying from very generalized to very specific. Some species have a cosmopolitan distribution, or occur throughout the temperate and tropical regions. Some are pests or vectors of plant viruses and phytoplasmas. The family is distributed all over the world, and constitutes the second-largest hemipteran family, with at least 20,000 described species.
Maconellicoccus hirsutus, is a pest of many plants, trees, and shrubs. It infests hibiscus, citrus, coffee, sugar cane, annonas, plums, guava, mango, okra, sorrel, teak, mora, pigeon pea, peanut, grapevine, maize, asparagus, chrysanthemum, beans, cotton, soybean, cocoa, and many other plants. The pest forms colonies on the host plant, and if left undisturbed, the colonies will grow into large masses of white waxy coverings on branches, fruiting structures, leaves, and even whole plants, including large trees.
The name sharpshooter is used to refer to any of various genera and species of large leafhoppers in the tribe Proconiini of the family Cicadellidae. As with all cicadellids, they have piercing-sucking mouthparts and closely spaced rows of fine spines on their hind legs. The nymphs feed by inserting their needle-like mouthparts into the xylem of the small stems on the plant where the eggs were deposited; the adults have wings and are highly mobile, and most feed on a variety of different plant species. Both nymphs and adults filter a huge volume of dilute liquid through their digestive system to extract the trace nutrients, and much of the water and carbohydrates are squirted forcibly away from the body in a fine stream of droplets, thus earning them their common name.
The beet leafhopper, also sometimes known as Neoaliturus tenellus, is a species of leafhopper which belongs to the family Cicadellidae in the order Hemiptera.
Orius insidiosus, common name the insidious flower bug, is a species of minute pirate bug, a predatory insect in the order Hemiptera. They are considered beneficial, as they feed on small pest arthropods and their eggs. They are mass-reared for use in the biological control of thrips.
Aphis gossypii is a tiny insect, an aphid ("greenfly") in the superfamily Aphidoidea in the order Hemiptera. It is a true bug and sucks sap from plants. It is a widely distributed pest of a variety of agricultural crops in the families Cucurbitaceae, Rutaceae and Malvaceae. Common names include cotton aphid, melon aphid and melon and cotton aphid.
Plexippus paykulli is a species of jumping spider. It is native to south east Asia but has spread to other parts of the world and globe. In the United States it is called the pantropical jumping spider. It is usually associated with buildings and may be found near light sources catching insects attracted by the light. It is named in honor of Gustaf von Paykull.
Paracoccus marginatus, commonly known as the papaya mealybug, is a small sap-sucking insect in the mealybug family, Pseudococcidae. It is found on a number of different hosts, including economically important tropical fruit trees and various ornamental plants.
Empoasca decipiens is a species of leafhopper belonging to the family Cicadellidae subfamily Typhlocybinae. The adults reach 3–4 millimetres (0.12–0.16 in) of length and a are homogenously green with whitish markings on its pronotum and vertex. E. decipiens is commonly referred to as the “green leafhopper” because of its colouration. The absence of clear stripes along the forewings can easily distinguish it from the similar leafhopper species E. vitis, but distinguishing it from other leafhoppers with the same colouration requires examination under a microscope. It is present in most of Europe, in the eastern Palearctic realm, in North Africa, in the Near East, and in the Afrotropical realm. Both nymphs and adults of this small insect are considered to be a very destructive pests on field crops, vegetables and greenhouse plants.
Empoasca fabae belongs to family Cicadellidae and genus Empoasca within order Hemiptera. They are more commonly referred to as the potato leafhopper. In North America they are a serious agricultural pest. Every year millions of dollars are lost from reduced crop yields and on pest management. Crops that are impacted the most are potatoes, clover, beans, apples and alfalfa.
Dysdercus suturellus is a species of true bug in the family Pyrrhocoridae, commonly known as a cotton stainer. The adult insect is slender, about 1 to 1.5 cm long, with a red thorax and dark brown wings marked with a yellow cross. It is native to the southeast of the United States, Jamaica and Puerto Rico. It is a pest of cotton crops and other plants, the adults and older nymphs feeding on the emerging bolls and the ripening seeds.
Rhynocoris marginatus is a species of assassin bug in the family Reduviidae. It is a predator of other insects and is found in Asia. Crops in India on which it has been found feeding on pests include sugarcane, pigeon pea, cardamom, cotton, tea, and peanuts. The insects are potentially useful in biological control because they are more resistant to pesticides than are the pests on which they feed.
Pyrilla perpusilla, commonly known as the sugarcane planthopper, is a planthopper in the family Lophopidae. It is native to Asia where it feeds on grasses and other plants and is a major pest of sugarcane and sorghum.
Scymnus (Scymnus) nubilus, is a species of lady beetle found in Pakistan, India, Bangladesh, Sri Lanka, Nepal, Myanmar, China, and Asia Minor.
Erasmoneura vulnerata is a species of leafhopper native to North America. The species was found to be in Europe in 2004 where it causes significant economic damage to grapevine yards. E. vulnerata is commonly found on wild and cultivated grapes from both continents. Its Latin name translates to "wounded Erasmoneura" from its original description.
Batkoa is a genus of fungi within the family of Entomophthoraceae and order Entomophthorales of the Zygomycota. This has been supported by molecular phylogenetic analysis.
