    Insects have a major impact on all of our lives, from vectoring plant and animal diseases to eating or pollinating our crops. Good or bad, all insects are potentially at risk from parasites and diseases, be they parasitic wasps and flies, entomopathogenic worms, or microbial pathogens such as .   In some groups, final-instar larvae enter a non-feeding prepupal phase, often overwintering as such and finally pupating in the spring. Insect eggs vary considerably in appearance. For example, they may be spherical, oval, hemispherical, cigar-shaped, flask-shaped or sausage-shaped; they are sometimes flattened, fried-egg-like structures (e.g.

Hymenoptera are also diverse in terms of their life histories: they include phytophagous, parasitoid, and predatory taxa, both solitary and highly social species, and they range in size from the rather large and intimidating spider-hunting pompilid wasps that can reach 12 cm wingspan down to the tiniest parasitic wasps that are approximately 0 Cited by: 6.

Metamorphosis complete; larva generally apodous with a more or less well-developed head, more rarely eruciform with locomotory appendages; tracheal system usually holopneustic or peripneustic throughout life, or at least in the final instar.

Pupae adecticous, exarate. Immature stages, particularly fi nal instars larvae, have been the subject of analyses in other groups of parasitic Hymenoptera (Vance & Smith ), in-cluding Ichneumonidae Latreille, Author: J. Cutler. With more t described species worldwide, parasitic wasps in the family Braconidae are the second largest group of Hymenoptera next to its sister lineage, Ichneumonidae.

The superfamily Ichneumonoidea contains one extinct and three extant families, including the two largest families within Hymenoptera: Ichneumonidae and group is thought to contain as many asspecies, many of which have not yet been described.

Like other parasitoid wasps, they were long placed in the "Parasitica", variously considered as an infraorder or an unranked clade Class: Insecta. The number of mandible exuviae is used as evidence for determining instar numbers, but dimorphism may occur within one larval instar, and sexual dimorphism in the larvae can be striking.

Metamorphosis is complete: egg, larva, pupa, adult (Borror, Triplehorn and Johnson, ). Sawfly larvae differ from larvae in the order Lepidoptera (butterflies and moths) by lacking noticeable body hairs, having a well-developed head, and possessing more.

Larvae of 30 species are described, illustrated and keyed. Sets of colour and black and white plates display these often beautifully colourful beetles, and their key features.

This stage is known as pupal stage (chrysalis in case of butterflies). The larvae begin to resemble adults at the end of this stage due to the anatomical modifications that take place in them and also due to the appearance of new organs and Author: Amritpal Singh Kaleka, Navkiran Kaur, Gaganpreet Kour Bali.

The beetle was first discovered by Thomas Nuttall in and was described in Suddenly, inthe Colorado potato began devastating potato crops miles west of Omaha, Nebraska, USA (Pope and Madge, ).Whether the attacks stemmed from a change in food preference by the beetle, or were the result of its first meeting with the cultivated potato, remains.
