Siphoninus is a genus of whiteflies in the family
Trialeurodes (Greenhouse whitefly) is a large genus of whiteflies in the family
is a large hemipteran family comprising the whiteflies. It contains the following species:
The Cabbage Whitefly ("Aleyrodes proletella") is a species of whitefly from the
family. It has a global distribution.
The taxonomic genus "Bemisia" within the family
, comprising some of the whiteflies, is named in her honor.
Whiteflies are small Hemipterans that typically feed on the undersides of plant leaves. They comprise the family
, the only family in the superfamily Aleyrodoidea. More than 1550 species have been described.
The digestive system of the
is typical of the Sternorrhyncha, including a filter chamber, and all active stages of the
accordingly produce large quantities of honeydew; the anus is adapted to presentation of honeydew to symbiotic species, mainly ants; the honeydew emerges from the anus, which is inside an opening called the on the dorsal surface of the caudal segment of the abdomen. This orifice is large and is covered by an operculum The entire structure is characteristic of the
and within the family it is taxonomically diagnostic because it varies in shape according to the species. Within the orifice beneath the operculum there is a tongue-like lingula. It appears to be involved in the expulsion of honeydew, and in fact at one time was wrongly assumed to be the organ that produced the honeydew. In some species it generally protrudes from beneath the operculum, but in others it normally is hidden.
Altus Lacy Quaintance (December 19, 1870 – August 7, 1958) was an American entomologist who specialized in the study of insect pests of fruit trees. He was recognized as an expert on
, a family of white flies that are major pests of citrus and greenhouse plants.
The eggs of
generally are laid near each other on the food plant, usually on a leaf, in spiral patterns or arcs, sometimes in parallel arcs. The egg is elongated, with one narrow end produced into a pedicel, which in some species is longer than the rest of the egg. After fertilisation the pedicel shrivels into a stalk.
Some pupae remain inside the exoskeleton of the final larval instar and this last larval "shell" is called a puparium (plural, puparia). Flies of the group Muscomorpha have puparia, as do members of the order Strepsiptera, and the Hemipteran family
are a family in the suborder Sternorrhyncha and at present comprise the entire superfamily Aleyrodoidea, related to the superfamily Psylloidea. The family often occurs in older literature as "Aleurodidae", but that is a junior synonym and accordingly incorrect in terms of the international standards for zoological nomenclature.
Aleurocanthus woglumi is a species of whitefly in the family
. It is a pest of citrus crops, and is commonly known as the citrus blackfly because of its slate-blue colour. It originated in Asia, but has spread to other parts of the world. The parasitic wasps, "Encarsia perplexa" and "Amitus hesperidum" can help control the pest.
The insects and their wings are variously marked or mottled according to species, and many species are covered with fine wax powder, giving most species a floury, dusted appearance, hence names such as
, Aleurodidae and "Aleuroduplidens"; the root refers to the (aleurodes) meaning "floury". However, not all species are white; for example, "Aleurocanthus woglumi" is slaty black.
This pupal stage is analogous to the pupal forms of the Endopterygota and it raises questions of terminology and concept. Some authorities argue that there is little functional, and no logically cogent basis for the distinction between the terms "larva" and "nymph". Some have long been in favour of dropping the term nymph entirely, and certainly apply the term "larvae" to the
Like most of the mobile Sternorrhyncha, adult
have well-developed antennae, which in most species in this family are seven-segmented. As in many Hemiptera, there are two ocelli, which generally in the
are placed at the anterior margins of the compound eyes. The compound eyes themselves however, are rather remarkable; there are many examples in entomology in which the upper and lower regions of the compound eye differ both functionally and anatomically, and in some families that are adapted to living on water surfaces, such as the Gyrinidae, they even may be divided into upper and lower eyes for vision in air and under water. However, although it is not clear why
should need any such adaptation, many have a distinct constriction between the upper and lower halves of the compound eyes in both sexes. In some species there is a complete separation. The degree of separation is useful in recognising the species; for instance, one way to tell adult "Bemisia" from "Trialeurodes" is that the upper and lower parts of the compound eyes are connected by a single ommatidium in Bemisia, while in Trialeurodes they are completely separate.
The adult wasps, tiny insects about 1 or 2 millimeters in size, are primarily parasitoids of sessile stages of Sternorrhyncha, in particular whiteflies (
) and scale insects (Diaspididae). A few species are known to parasitize aphids, eggs of shield-back bugs (Plataspidae), and eggs of Lepidoptera. Females mostly develop as primary endoparasitoids, and males are commonly hyperparasitoids of the same or other species. This so-called heteronomy, a sexually dimorphic host relationship, occurs in quite a few species.
"Belonogaster juncea juncea" will typically feed and provide food to their larvae in the forms of either liquid matter or prey. Liquid matter primarily consists of honeydew and nectar from various species of plants. In order to obtain this liquid manner, they exhibit a relationship with
(whiteflies) and can parasitize the various trees or leaves in order to extract fluids. Their prey includes various species of insects such as caterpillars, winged ants, and grasshoppers.
They are distinguished from the Endopterygota (or Holometabola) by the way in which their wings develop. Endopterygota (meaning literally "internal winged forms") develop wings inside the body and undergo an elaborate metamorphosis involving a pupal stage. Exopterygota ("external winged forms") develop wings on the outside of their bodies without going through a true pupal stage, though a few have something resembling a pupa (e.g.,
The silverleaf whitefly ("Bemisia tabaci", also informally referred to as the sweetpotato whitefly) is one of several whiteflies that are currently important agricultural pests. The silverleaf whitefly is classified in the family
, and is included in the large sub-order of insects, Sternorrhyncha. A review in 2011 concluded that the silverleaf whitefly is actually a species complex containing at least 24 morphologically indistinguishable species.
Tomato yellow leaf curl virus (TYLCV) is a DNA virus from the genus "Begomovirus" and the family "Geminiviridae". TYLCV causes the most destructive disease of tomato, and it can be found in tropical and subtropical regions causing severe economic losses. This virus is transmitted by an insect vector from the family "
" and order "Hemiptera", the whitefly "Bemisia tabaci", commonly known as the silverleaf whitefly or the sweet potato whitefly. The primary host for TYLCV is the tomato plant, and other plant hosts where TYLCV infection has been found include eggplants, potatoes, tobacco, beans, and peppers. Due to the rapid spread of TYLCV in the last few decades, there is an increased focus in research trying to understand and control this damaging pathogen. Some interesting findings include virus being sexually transmitted from infected males to non-infected females (and vice versa), and an evidence that TYLCV is transovarially transmitted to offspring for two generations.
