Amblyseius Swirskii
''Typhlodromips swirskii'', the Swirski mite (synonymy: ''Amblyseius swirskii'', ''Amblyseius rykei'', ''Neoseiulus swirskii''), is a species of predatory mite in the family Phytoseiidae. It is used in biological pest control of western flower thrips (''Frankliniella occidentalis'')in greenhouse or indoor grown crops. Description The adult ''T. swirskii'' has a pear-shaped body and is about in length. It has four pairs of legs, the front pair of which points forward, and a small number of paired bristles on the unsegmented body. The colour varies with the diet, being pale yellow or tan when thrips and whitefly are eaten, and reddish on some other diets. It is difficult to distinguish one species of predatory mite from another in the field. Distribution and habitat ''T. swirskii'' is native to the eastern Mediterranean region where its range includes Italy, Cyprus, Greece, Turkey, Israel and Egypt. It is used as an agent of biological control on crops such as apple, apricot, citr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Whitefly
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. Description and taxonomy The Aleyrodidae 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. Aleyrodidae are small insects, most species with a wingspan of less than 3 mm and a body length of 1 mm to 2 mm. Many are so small that their size complicates their control in greenhouses because they can only be excluded by screening with very fine mesh; in fact they can enter mesh so fine that many of their natural enemies cannot come in after them, so that unchecked whitefly populations ...

Polyphagotarsonemus Latus
The broad mite, ''Polyphagotarsonemus latus'' (Acari: Tarsonemidae), is a microscopic species of mite found on many species of plants, including important agricultural species such as grapes, apples, and other fruits. Broad mites are also currently affecting cannabis plants, as the industry matures with legalization. The mites are found in many areas throughout the world and are major pests in greenhouses. A ''P. latus'' infestation can cause stunting and twisting of the leaves and flowers, and blackening and death of new growth. The damage resembles that caused by herbicides. The mites prefer areas of high humidity and low temperature. They can be controlled by removing and destroying infested plants, and spraying with an acaricide Acaricides are pesticides that kill members of the arachnid subclass ''Acari'', which includes ticks and mites. Acaricides are used both in medicine and agriculture, although the desired selective toxicity differs between the two fields. Termino . ...

Asian Citrus Psyllid
''Diaphorina citri'', the Asian citrus psyllid, is a sap-sucking, hemipteran bug in the family Psyllidae. It is one of two confirmed vectors of citrus greening disease. It has a wide distribution in southern Asia and has spread to other citrus growing regions. Distribution The Asian citrus psyllid originated in Asia but it is now also found in parts of the Middle East, South and Central America, Mexico, and the Caribbean. In the United States, the psyllid was first detected in Florida in 1998 and is now also found in Louisiana, Georgia, Arizona, South Carolina, Texas, and since 2003 in California. In Southern California, the San Joaquin Valley, and Central Coast counties, such as San Luis Obispo, an eradication program has been instituted in an attempt to prevent it from becoming established. In the whole of the United States and its territories, areas where this psyllid are found are under quarantine restrictions. Description The adult psyllid is about four millimetres long ...

Greenhouse Whitefly
''Trialeurodes vaporariorum'', commonly known as the glasshouse whitefly or greenhouse whitefly, is an insect that inhabits the world's temperate regions. Like various other whiteflies, it is a primary insect pest of many fruit, vegetable and ornamental crops. It is frequently found in glasshouses ( greenhouses), polytunnels, and other protected horticultural environments. Adults are 1–2 mm in length, with yellowish bodies and four wax-coated wings held near parallel to the leaf surface. Life cycle Females are capable of mating less than 24 hours after emergence and most frequently lay their eggs on the undersides of leaves. Eggs are pale yellow in colour, before turning grey prior to hatching. Newly hatched nymphs, often known as crawlers, are the only mobile immature life-stage. During the first and second nymph instars, the appearance is that of a pale yellow/translucent, flat scale which can be difficult to distinguish with the naked eye. During the fourth and final ...

Silverleaf Whitefly
The silverleaf whitefly (''Bemisia tabaci'', also informally referred to as the sweet potato 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. The silverleaf whitefly thrives worldwide in tropical, subtropical, and less predominately in temperate habitats. Cold temperatures kill both the adults and the nymphs of the species. The silverleaf whitefly can be confused with other insects such as the common fruitfly, but with close inspection, the whitefly is slightly smaller and has a distinct wing color that helps to differentiate it from other insects. While the silverleaf whitefly had been known in the United States since 1896, in the mid-1980s an aggressive strain appeared in poinsettia crops in Florida. For convenience that strain was referred to as (biotype B), to distinguish it f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Onion Thrips
''Thrips tabaci'' is a species of very small insect in the genus ''Thrips'' in the order Thysanoptera. It is commonly known as the onion thrips, the potato thrips, the tobacco thrips or the cotton seedling thrips. It is an agricultural pest that can damage crops of onions and other plants, and it can additionally act as a vector for plant viruses. Description In some populations, nearly all onion thrips are female, and males are very rare. The adult onion thrips is some long. The body is some shade of yellow, yellowish-brown or brown; the antennae have seven segments, the wings are well-developed and females have an ovipositor at the tip of the abdomen. Distribution and host range The onion thrips is thought to have originated in the Mediterranean region but is now found on all continents except Antarctica.

Common Blossom Thrips
''Frankliniella schultzei'', the common blossom thrips or cotton thrips, is a species of thrips in the family Thripidae. It is found in many parts of the world and is an important pest insect in agriculture. Description The adult common blossom thrips is a very small insect with a length of between . There are two colour morphs, a dark form and a pale form, each occupying part of the range, with forms of both colours being reported from Egypt, India, Kenya, New Guinea, Puerto Rico, Sudan and Uganda. Identification of thrips species is dependent on the colour, the number and arrangement of the bristles on the body and the details of the comb on the eighth abdominal segment. Species status Morphological, biological, molecular and ecological data has demonstrated that the dark and light "forms" of ''F. schultzei'' in Kenya are two distinct species. Genetic analysis of ''F. schultzei'' in Australia shows that there are three highly divergent species of thrips under the taxonomic name ...

Predation
Predation is a biological interaction where one organism, the predator, kills and eats another organism, its prey. It is one of a family of common feeding behaviours that includes parasitism and micropredation (which usually do not kill the host) and parasitoidism (which always does, eventually). It is distinct from scavenging on dead prey, though many predators also scavenge; it overlaps with herbivory, as seed predators and destructive frugivores are predators. Predators may actively search for or pursue prey or wait for it, often concealed. When prey is detected, the predator assesses whether to attack it. This may involve ambush or pursuit predation, sometimes after stalking the prey. If the attack is successful, the predator kills the prey, removes any inedible parts like the shell or spines, and eats it. Predators are adapted and often highly specialized for hunting, with acute senses such as vision, hearing, or smell. Many predatory animals, both vertebrate and inv ...

Biological Control
Biological control or biocontrol is a method of controlling pests, such as insects, mites, weeds, and plant diseases, using other organisms. It relies on predation, parasitism, herbivory, or other natural mechanisms, but typically also involves an active human management role. It can be an important component of integrated pest management (IPM) programs. There are three basic strategies for biological pest control: classical (importation), where a natural enemy of a pest is introduced in the hope of achieving control; inductive (augmentation), in which a large population of natural enemies are administered for quick pest control; and inoculative (conservation), in which measures are taken to maintain natural enemies through regular reestablishment. Natural enemies of insect pests, also known as biological control agents, include predators, parasitoids, pathogens, and competitors. Biological control agents of plant diseases are most often referred to as antagonists. Biologic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
