Wormlike or grublike stage, following the egg in the life cycle of insects, worms, and other metamorphosing animals.

INSECTS of the order Coleoptera, containing over 350,000 species in 150 families. They possess hard bodies and their mouthparts are adapted for chewing.

The relationship between an invertebrate and another organism (the host), one of which lives at the expense of the other. Traditionally excluded from definition of parasites are pathogenic BACTERIA; FUNGI; VIRUSES; and PLANTS; though they may live parasitically.

Insects of the suborder Heterocera of the order LEPIDOPTERA.

Insects that transmit infective organisms from one host to another or from an inanimate reservoir to an animate host.

The immature stage in the life cycle of those orders of insects characterized by gradual metamorphosis, in which the young resemble the imago in general form of body, including compound eyes and external wings; also the 8-legged stage of mites and ticks that follows the first moult.

Paired sense organs connected to the anterior segments of ARTHROPODS that help them navigate through the environment.

A plant family in the order Sapindales that grows in warmer regions and has conspicuous flowers.

Use of naturally-occuring or genetically-engineered organisms to reduce or eliminate populations of pests.

A suborder of chewing lice, in the order PHTHIRAPTERA, that are ectoparasites of poultry and some mammals.

A plant genus of the family Plantaginaceae. The small plants usually have a dense tuft of basal leaves and long, leafless stalks bearing a terminal spike of small flowers. The seeds, known as PSYLLIUM, swell in water and are used as laxatives. The leaves have been used medicinally.

A discipline or occupation concerned with the study of INSECTS, including the biology and the control of insects.

The act of feeding on plants by animals.

The reduction or regulation of the population of mosquitoes through chemical, biological, or other means.

Sexual activities of animals.

Number of individuals in a population relative to space.

Chemical substances, excreted by an organism into the environment, that elicit behavioral or physiological responses from other organisms of the same species. Perception of these chemical signals may be olfactory or by contact.

Collective name for a group of external MECHANORECEPTORS and chemoreceptors manifesting as sensory structures in ARTHROPODS. They include cuticular projections (setae, hairs, bristles), pores, and slits.

The total process by which organisms produce offspring. (Stedman, 25th ed)

Behavioral responses or sequences associated with eating including modes of feeding, rhythmic patterns of eating, and time intervals.

A plant genus of the family ANACARDIACEAE. This is the source of the familiar cashew nuts, which are heat treated to remove the irritant toxin. Cashew nut shell liquid (frequently abbreviated as CNSL) is a major source of alkenyl phenolic compounds, especially ANACARDIC ACIDS, cardol, and cardanol.

Proteins, usually projecting from the cilia of olfactory receptor neurons, that specifically bind odorant molecules and trigger responses in the neurons. The large number of different odorant receptors appears to arise from several gene families or subfamilies rather than from DNA rearrangement.

A suborder of chewing lice, in the order PHTHIRAPTERA, that are parasites of birds and mammals.

A type of MONOTERPENES, derived from geraniol. They have the general form of cyclopentanopyran, but in some cases, one of the rings is broken as in the case of secoiridoid. They are different from the similarly named iridals (TRITERPENES).

A plant genus of the family MORACEAE. It is the source of the familiar fig fruit and the latex from this tree contains FICAIN.

The number of offspring produced at one birth by an oviparous or ovoviviparous animal.

The observable response an animal makes to any situation.

The reduction or regulation of the population of noxious, destructive, or dangerous insects through chemical, biological, or other means.

A family of insect viruses isolated from endoparasitic hymenopteran insects belonging to the families Ichneumonidae and Braconidae. The two genera are Ichnovirus and Bracovirus.

A plant genus of the family ARISTOLOCHIACEAE. Species of this genus have been used in traditional medicine but they contain aristolochic acid which is associated with nephropathy. These are sometimes called 'snakeroot' but that name is also used with a number of other plants such as POLYGALA; SANICULA; ASARUM; ARISTOLOCHIA; AGERATINA; and others.

Instinctual behavior pattern in which food is obtained by killing and consuming other species.

An inactive stage between the larval and adult stages in the life cycle of insects.

Substances causing insects to turn away from them or reject them as food.

Ducts that serve exclusively for the passage of eggs from the ovaries to the exterior of the body. In non-mammals, they are termed oviducts. In mammals, they are highly specialized and known as FALLOPIAN TUBES.

A large order of insects comprising the butterflies and moths.

A plant genus of the family POACEAE. Folin is the water-soluble extract from Sasa albomarginata. Sasa kurinensis is an ingredient of Sho-ju-sen, a Japanese herbal medicine.

A plant genus of the family Gentianaceae whose members contain SECOIRIDOIDS and have been used in TRADITIONAL MEDICINE for suppressing INFLAMMATION.

Family of spider MITES, in the superfamily Tetranychoidea, suborder Trombidiformes.

Substituted thioglucosides. They are found in rapeseed (Brassica campestris) products and related cruciferae. They are metabolized to a variety of toxic products which are most likely the cause of hepatocytic necrosis in animals and humans.

A family of the order DIPTERA that comprises the mosquitoes. The larval stages are aquatic, and the adults can be recognized by the characteristic WINGS, ANIMAL venation, the scales along the wing veins, and the long proboscis. Many species are of particular medical importance.

The transfer of POLLEN grains (male gametes) to the plant ovule (female gamete).

An acute febrile disease transmitted by the bite of AEDES mosquitoes infected with DENGUE VIRUS. It is self-limiting and characterized by fever, myalgia, headache, and rash. SEVERE DENGUE is a more virulent form of dengue.
