Diprion Pini
The common pine sawfly, ''Diprion pini'', is a sawfly species in the family Diprionidae. It is a serious pest of economic forestry, capable of defoliating large areas of pine forest. It occurs throughout Europe and Russia. Description ''Diprion pini'' is an insect with complete metamorphosis, changing from a caterpillar larva via a pupal stage to a winged adult. Last-stage larvae can be up to long; the head is brown, while the body is light green with black spots. The adult (imago) is brown and is around long. The larvae feed on pine needles. Eggs are laid in rows in springtime, on pine needles from the previous year. Young caterpillars start feeding on the old needles near where they hatched, leaving the vascular bundles uneaten. Older caterpillars feed more widely, moving to other branches and eating whole needles except for the leaf sheath; late in the season they also consume the current year's needles. The caterpillars live in groups of some 60 to 100 individuals. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carl Linnaeus
Carl Linnaeus (23 May 1707 – 10 January 1778), also known after ennoblement in 1761 as Carl von Linné,#Blunt, Blunt (2004), p. 171. was a Swedish biologist and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern Taxonomy (biology), taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was the son of a curate and was born in Råshult, in the countryside of Småland, southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Diflubenzuron
Diflubenzuron is an insecticide of the benzoylurea class. It is used in forest management and on field crops to selectively control insect pests, particularly forest tent caterpillar moths, boll weevils, gypsy moths, and other types of moths. It is a widely used larvicide in India for control of mosquito larvae by public health authorities. Diflubenzuron is approved by the WHO Pesticide Evaluation Scheme. Mechanism of action The mechanism of action of diflubenzuron involves inhibiting the production of chitin which is used by an insect to build its exoskeleton. It triggers insect larvae to molt early without a properly formed exoskeleton, resulting in the death of the larvae. Environmental toxicity Diflubenzuron has been evaluated by the United States Environmental Protection Agency (EPA), and it is classified as non-carcinogenic. 4-Chloroaniline, a metabolite of diflubenzuron which has been classified as a carcinogen, is produced after diflubenzuron has been ingested.

Pheromone Trap
A pheromone trap is a type of insect trap that uses pheromones to lure insects. Sex pheromones and aggregating pheromones are the most common types used. A pheromone-impregnated lure is encased in a conventional trap such as a bottle trap, delta trap, water-pan trap, or funnel trap. Pheromone traps are used both to count insect populations by sampling, and to trap pests such as clothes moths to destroy them. Sensitivity Pheromone traps are very sensitive, meaning they attract insects present at very low densities. They are often used to detect presence of exotic pests, or for sampling, monitoring, or to determine the first appearance of a pest in an area. They can be used for legal control, and are used to monitor the success of the Boll Weevil Eradication Program and the spread of the spongy moth. The high species-specificity of pheromone traps can also be an advantage, and they tend to be inexpensive and easy to implement. This sensitivity is especially suited to some inve ...

Pine Weevil
''Hylobius abietis'' or the large pine weevil is a beetle belonging to family Curculionidae. This species is widely regarded as the most important pest of most commercially important coniferous trees in European plantations. Seedlings planted or arising from natural regeneration (germinated seed-fall) after clear felling operations are especially at risk. The adult weevils cause damage by eating the bark of seedlings around the 'collar' of the stem, thus 'ring-barking' the tree seedling which usually results in its demise. Description The adult weevils are approximately in length (without beak/snout) and are dark brown with patches of yellow or light brown hairs arranged in irregular rows on their elytra. The legs are black or deep red with a distinctive tooth on the femora and at the end of tibiae. The full grown larvae are , typical for weevils, apodial, curved and are whitish, with brown head.

Buprestidae
Buprestidae is a family (biology), family of beetles known as jewel beetles or metallic wood-boring beetles because of their glossy Iridescence, iridescent colors. Larvae of this family are known as flatheaded borers. The family is among the largest of the beetles, with some 15,500 species known in 775 genera. In addition, almost 100 fossil species have been described. The larger and more spectacularly colored jewel beetles are highly prized by insect collectors. The elytra of some Buprestidae species have been traditionally used in beetlewing jewellery and decoration in certain countries in Asia, like India, Thailand and Japan. Description and ecology Shape is generally cylindrical or elongate to ovoid, with lengths ranging from , although most species are under . ''Catoxantha'', ''Chrysaspis (beetle), Chrysaspis'', ''Euchroma'' and ''Megaloxantha'' contain the largest species. A variety of bright colors are known, often in complicated patterns. The iridescence common to these ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bark Beetle
A bark beetle is the common name for the subfamily of beetles Scolytinae. Previously, this was considered a distinct family (Scolytidae), but is now understood to be a specialized clade of the "true weevil" family (Curculionidae). Although the term "bark beetle" refers to the fact that many species feed in the inner bark (phloem) layer of trees, the subfamily also has many species with other lifestyles, including some that bore into wood, feed in fruit and seeds, or tunnel into herbaceous plants. Well-known species are members of the type genus '' Scolytus'', namely the European elm bark beetle ''S. multistriatus'' and the large elm bark beetle ''S. scolytus'', which like the American elm bark beetle '' Hylurgopinus rufipes'', transmit Dutch elm disease fungi (''Ophiostoma''). The mountain pine beetle ''Dendroctonus ponderosae'', southern pine beetle '' Dendroctonus frontalis'', and their near relatives are major pests of conifer forests in North America.

Deimatic Behaviour
Deimatic behaviour or startle display means any pattern of bluffing behaviour in an animal that lacks strong defences, such as suddenly displaying conspicuous eyespots, to scare off or momentarily distract a predator, thus giving the prey animal an opportunity to escape. The term deimatic or dymantic originates from the Greek δειματόω (deimatóo), meaning "to frighten". Deimatic display occurs in widely separated groups of animals, including moths, butterflies, mantises and phasmids among the insects. In the cephalopods, different species of octopuses, squids, cuttlefish and the paper nautilus are deimatic. Displays are classified as deimatic or aposematic by the responses of the animals that see them. Where predators are initially startled but learn to eat the displaying prey, the display is classed as deimatic, and the prey is bluffing; where they continue to avoid the prey after tasting it, the display is taken as aposematic, meaning the prey is genuinely distaste ...
