The light brown apple moth is a leafroller moth belonging to the lepidopteran family Tortricidae.
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 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.
Exapion fuscirostre is a species of straight-snouted weevil known by the general common name Scotch broom seed weevil. It is used as an agent of biological pest control against the noxious weed known as Scotch broom.
The fall armyworm is a species in the order Lepidoptera and is the larval life stage of a fall armyworm moth. The term "armyworm" can refer to several species, often describing the large-scale invasive behavior of the species' larval stage. It is regarded as a pest and can damage and destroy a wide variety of crops, which causes large economic damage. Its scientific name derives from frugiperda, which is Latin for lost fruit, named because of the species' ability to destroy crops. Because of its propensity for destruction, the fall armyworm's habits and possibilities for crop protection have been studied in depth. It is also a notable case for studying sympatric speciation, as it appears to be diverging into two species currently. Another remarkable trait of the larva is that they practice cannibalism as a disease control mechanism.
Diabrotica speciosa, also known as the cucurbit beetle and in Spanish as vaquita de San Antonio is an insect pest native to South America. Its larvae feed on the roots of crops. The cucurbit beetle is also known to transmit several viruses such as comoviruses and different mosaic viruses. Diabrotica speciosa is native to South America and is now distributed in Central America and other global areas.
Lixus concavus, commonly called the rhubarb curculio, is a species of weevil. Rhubarb is a host, together with dock, sunflower, and thistle.
Busseola fusca is a species of moth that is also known as the maize stalk borer. It is known from Ethiopia.
Gonipterus scutellatus is a species of weevil in the family Curculionidae. It is commonly known as the eucalyptus snout beetle, the eucalyptus weevil or the gum tree weevil. It feeds and breeds on Eucalyptus trees and is endemic to Australia.
Plant use of endophytic fungi in defense occurs when endophytic fungi, which live symbiotically with the majority of plants by entering their cells, are utilized as an indirect defense against herbivores. In exchange for carbohydrate energy resources, the fungus provides benefits to the plant which can include increased water or nutrient uptake and protection from phytophagous insects, birds or mammals. Once associated, the fungi alter nutrient content of the plant and enhance or begin production of secondary metabolites. The change in chemical composition acts to deter herbivory by insects, grazing by ungulates and/or oviposition by adult insects. Endophyte-mediated defense can also be effective against pathogens and non-herbivory damage.
Chilo infuscatellus, the yellow top borer or sugarcane shoot borer, is a moth in the family Crambidae. It was described by the Dutch entomologist Samuel Constantinus Snellen van Vollenhoven in 1890. It is found in India, Myanmar, Tajikistan, Afghanistan, Korea, Taiwan, Malaysia, the Philippines and on Java and Timor.
Chilo partellus, the spotted stalk borer or spotted stem borer, is a moth in the family Crambidae. It was described by Charles Swinhoe in 1885. It is found in India, Pakistan, Ethiopia, Lesotho, Madagascar, Malawi, South Africa, Sudan, Tanzania, Uganda and on Mayotte.
Perennial ryegrass staggers is poisoning by peramine, lolitrem B, and other toxins that are contained in perennial ryegrass, and produced by the endophyte fungus Neotyphodium lolii which can be present in all parts of the grass plant, but tends to be concentrated in the lower part of the leaf sheaths, the flower stalks and seeds. This condition can affect horses, cattle, sheep, farmed deer and llamas. It regularly occurs in New Zealand and is known spasmodically from Australia, North and South America, and Europe.
Hypera postica, commonly known as the alfalfa weevil, is a species of beetle in the superfamily Curculionoidea; it can be found in alfalfa fields throughout Europe. Considered a destructive threat to alfalfa production in North America, several accidental introductions have been successfully countered though the use of a variety of biological control species.
The annual bluegrass weevil, scientific name Listronotus maculicollis, is a turfgrass insect pest which feeds mainly on annual bluegrass. They prefer to feed on very low mown grass, and are thus found mostly on golf courses or grass tennis courts. ABWs, as they are often referred to, were only found in the Northeastern United States until the 2000s when sightings began to expand. In recent years they have been found as far north as Ontario and Quebec, as far west as Ohio, and as far south as North Carolina. Their choice of hosts has also expanded, and they have been reported feeding on perennial ryegrass and creeping bentgrass.
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 of potato plants, the larvae tunnelling inside their stems.
Listronotus oregonensis, the carrot weevil, is a species of weevil in the beetle family Curculionidae. It is found in North America.
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.
The lemon tree borer, also known as the whistling beetle or the singing beetle, is a longhorn beetle endemic to New Zealand. Its larvae are generalist feeders, boring into the wood of a wide variety of trees, native and introduced. When citrus orchards were first established in New Zealand, this beetle started inflicting serious damage, and so gained the name "lemon tree borer". Four species within the genus Oemona have been identified, suggesting that more species could be found. When disturbed by predators or humans, the adult beetle stridulates creating a "rasp" or "squeak" sound by rubbing its thorax and head together against an area of thin ridges. Māori would eat a liquid called "pia manuka", which was produced by manuka trees when its wood was damaged by the larva. When Captain Cook first arrived in NZ, his naturalists, Banks and Solander, collected a lemon tree borer in their first collection between 1769-1771. This oldest collected specimen can be found in the British Museum. A few years after the first collection, the species would be first described by the Danish naturalist Fabricius in 1775.
Cosmopolites sordidus, commonly known as the banana root borer, banana borer, or banana weevil, is a species of weevil in the family Curculionidae. It is a pest of banana cultivation and has a cosmopolitan distribution, being found in all parts of the world in which bananas are grown. It is considered the most serious insect pest of bananas.
