Trichobaris Trinotata
''Trichobaris trinotata'', commonly known as the "Potato stalk borer", is a species of weevil in the family Curculionidae. It is found in North America where it is a Pest (organism), pest of potato plants, the larvae tunnelling inside their stems. Description The adult weevil is a small species with a length of about and a width of about . The Rostrum (anatomy), rostrum or beak bends sharply downwards at the base. The insect is inconspicuous; it is black in color but appears gray as most of the surface is covered by minute gray scales; scales are absent from the head and from three spots at the base of the Elytron, elytra, one at the front and one on either side, and these appear dark. These three bare spots give the insect its scientific name of "trinotata". Ecology This weevil feeds on plants in the family Solanaceae. The potato is its most economically-important food plant, but it sometimes feeds on the eggplant (''Solanum melongena''), the Solanum carolinense, Carolina hor ...

Animalia
Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, can reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of cells, the blastula, during embryonic development. Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology. Most living animal species are in Bilateria, a clade whose members have a bilaterally symmetric body plan. The Bilateria include the protostomes, containing animals such as nematodes, arthropods, flatworms, annelids and molluscs, and the deuterostomes, containing the echinode ...

Eggplant
Eggplant ( US, Canada), aubergine ( UK, Ireland) or brinjal (Indian subcontinent, Singapore, Malaysia, South Africa) is a plant species in the nightshade family Solanaceae. ''Solanum melongena'' is grown worldwide for its edible fruit. Most commonly purple, the spongy, absorbent fruit is used in several cuisines. Typically used as a vegetable in cooking, it is a berry by botanical definition. As a member of the genus ''Solanum'', it is related to the tomato, chili pepper, and potato, although those are of the New World while the eggplant is of the Old World. Like the tomato, its skin and seeds can be eaten, but, like the potato, it is usually eaten cooked. Eggplant is nutritionally low in macronutrient and micronutrient content, but the capability of the fruit to absorb oils and flavors into its flesh through cooking expands its use in the culinary arts. It was originally domesticated from the wild nightshade species ''thorn'' or ''bitter apple'', '' S. incanum'',Tsao ...

Beetles Described In 1831
Beetles are insects that form the order Coleoptera (), in the superorder Endopterygota. Their front pair of wings are hardened into wing-cases, elytra, distinguishing them from most other insects. The Coleoptera, with about 400,000 described species, is the largest of all orders, constituting almost 40% of described insects and 25% of all known animal life-forms; new species are discovered frequently, with estimates suggesting that there are between 0.9 and 2.1 million total species. Found in almost every habitat except the sea and the polar regions, they interact with their ecosystems in several ways: beetles often feed on plants and fungi, break down animal and plant debris, and eat other invertebrates. Some species are serious agricultural pests, such as the Colorado potato beetle, while others such as Coccinellidae (ladybirds or ladybugs) eat aphids, scale insects, thrips, and other plant-sucking insects that damage crops. Beetles typically have a particularly hard exoske ...

Agricultural Pest Insects
A pest is any animal or plant harmful to humans or human concerns. The term is particularly used for creatures that damage crops, livestock, and forestry or cause a nuisance to people, especially in their homes. Humans have modified the environment for their own purposes and are intolerant of other creatures occupying the same space when their activities impact adversely on human objectives. Thus, an elephant is unobjectionable in its natural habitat but a pest when it tramples crops. Some animals are disliked because they bite or sting; snakes, wasps, ants, bed bugs, fleas and ticks belong in this category. Others enter the home; these include houseflies, which land on and contaminate food, beetles, which tunnel into the woodwork, and other animals that scuttle about on the floor at night, like cockroaches, which are often associated with unsanitary conditions. Agricultural and horticultural crops are attacked by a wide variety of pests, the most important being insects, mite ...

Eurytomidae
The Eurytomidae are a family within the superfamily Chalcidoidea. Unlike most chalcidoids, the larvae of many are phytophagous (feeding in stems, seeds, or galls), while others are more typical parasitoids, though even then the hosts are usually found within plant tissues. They are found throughout the world in virtually all habitats, and a few are considered pests. They tend to be dull and not metallic, and heavily punctured, with very thick, collar-like pronota. Taxa , Eurytomid genera include: Buresiinae Lotfalizadeh et al, 2007 * '' Buresium'' * '' Macrorileya'' Eurytominae * '' Aiolomorphus'' * '' Aranedra'' * '' Austrodecatoma'' * '' Ausystole'' * '' Axanthosoma'' * '' Axanthosomella'' * '' Axima'' * '' Aximopsis'' * '' Banyoma'' * '' Bephrata'' * '' Bephratelloides'' * '' Bephratoides'' * '' Bruchodape'' * ''Bruchophagus'' * '' Burksoma'' * '' Camponotophilus'' * '' Cathilaria'' * '' Chryseida'' * '' Chryseurytoma'' * '' Endobia'' * '' Eudoxin ...

Nealiolus Curculionis
''Nealiolus curculionis'' is a species of parasitic wasp in the family Braconidae. It is a parasitoid of the sunflower stem weevil '' Cylindrocopturus adspersus'', and a number of other species of stem-boring weevils. Description ''Nealiolus curculionis'' has a body length of just under . It has an oval shape, a moderately-curved carapace and a transverse clypeus, and the third tergite is finely sculpted with longitudinal lines. The color is basically black apart from the legs, which are brown, the dark brown antennae, the brown clypeus and mandibles, the brown ovipositor and the dark brown tip of the abdomen. Distribution This wasp is found in Canada, the United States and Mexico, and has also been recorded in Costa Rica, Guatemala and Venezuela. Life cycle This wasp shows a considerable degree of synchronization with its host species. When parasitizing the sunflower stem weevil, the female wasp lays a single egg into a first instar larva, which feeds just under the epid ...

Braconidae
The Braconidae are a family of parasitoid wasps. After the closely related Ichneumonidae, braconids make up the second-largest family in the order Hymenoptera, with about 17,000 recognized species and many thousands more undescribed. One analysis estimated a total between 30,000 and 50,000, and another provided a narrower estimate between 42,000 and 43,000 species. Classification The Braconidae are currently divided into about 47 subfamilies and over 1000 genera, which include ''Aerophilus'', ''Aleiodes'', '' Apanteles'', ''Asobara'', '' Bracon'', ''Cenocoelius'', '' Chaenusa'', ''Chorebus'', '' Cotesia'', '' Dacnusa'', '' Diachasma'', ''Microgaster'', ''Opius'', ''Parapanteles'', '' Phaenocarpa'', ''Spathius'', and ''Syntretus.'' These fall into two major groups, informally called the cyclostomes and noncyclostomes. In cyclostome braconids, the labrum and the lower part of the clypeus are concave with respect to the upper clypeus and the dorsal margin of the mandibles. The ...

Parasitoid Wasp
Parasitoid wasps are a large group of hymenopteran superfamilies, with all but the wood wasps (Orussoidea) being in the wasp-waisted Apocrita. As parasitoids, they lay their eggs on or in the bodies of other arthropods, sooner or later causing the death of these hosts. Different species specialise in hosts from different insect orders, most often Lepidoptera, though some select beetles, flies, or bugs; the spider wasps (Pompilidae) exclusively attack spiders. Parasitoid wasp species differ in which host life-stage they attack: eggs, larvae, pupae, or adults. They mainly follow one of two major strategies within parasitism: either they are endoparasitic, developing inside the host, and koinobiont, allowing the host to continue to feed, develop, and moult; or they are ectoparasitic, developing outside the host, and idiobiont, paralysing the host immediately. Some endoparasitic wasps of the superfamily Ichneumonoidea have a mutualistic relationship with polydnaviruses, the vir ...

Instar
An instar (, from the Latin '' īnstar'', "form", "likeness") is a developmental stage of arthropods, such as insects, between each moult (''ecdysis''), until sexual maturity is reached. Arthropods must shed the exoskeleton in order to grow or assume a new form. Differences between instars can often be seen in altered body proportions, colors, patterns, changes in the number of body segments or head width. After shedding their exoskeleton (moulting), the juvenile arthropods continue in their life cycle until they either pupate or moult again. The instar period of growth is fixed; however, in some insects, like the salvinia stem-borer moth, the number of instars depends on early larval nutrition. Some arthropods can continue to moult after sexual maturity, but the stages between these subsequent moults are generally not called instars. For most insect species, an ''instar'' is the developmental stage of the larval forms of holometabolous (complete metamorphism) or nymphal forms o ...

Diapause
In animal dormancy, diapause is the delay in development in response to regular and recurring periods of adverse environmental conditions.Tauber, M.J., Tauber, C.A., Masaki, S. (1986) ''Seasonal Adaptations of Insects''. Oxford University Press It is a physiological state with very specific initiating and inhibiting conditions. The mechanism is a means of surviving predictable, unfavorable environmental conditions, such as temperature extremes, drought, or reduced food availability. Diapause is observed in all the life stages of arthropods, especially insects. Embryonic diapause, a somewhat similar phenomenon, occurs in over 130 species of mammals, possibly even in humans, and in the embryos of many of the oviparous species of fish in the order Cyprinodontiformes. Activity levels of diapausing stages can vary considerably among species. Diapause may occur in a completely immobile stage, such as the pupae and eggs, or it may occur in very active stages that undergo extensive migrat ...

Physalis
''Physalis'' (, , , , from φυσαλλίς ''phusallís'' "bladder") is a genus of approximately 75 to 90 flowering plants in the Solanum, nightshade family (biology), family (Solanaceae), which are native to the Americas and Australasia. At least 46 species are endemism, endemic to Mexico. Cultivated and weedy species have been introduced worldwide. A defining feature of ''Physalis'' is a large, papery husk derived from the sepal, calyx, which partly or fully encloses the fruit. Many species bear edible fruit, and some species are cultivated. The typical ''Physalis'' fruit is similar to a firm tomato in texture, and like strawberry, strawberries or pineapple in flavor, with a mild acidity. Some species, such as the Physalis peruviana, Cape gooseberry and tomatillo, have been bred into many cultivars with varying flavors, from tart to sweet to savory. Nations including Colombia, India, and Mexico have a significant economic trade in ''Physalis'' fruit. The fruit of many species ...
