Aulacophora foveicollis, the red pumpkin beetle, is a species of beetle in the family Chrysomelidae. It is a foliar pest of members of the Cucurbitaceae, particularly the pumpkin. [2] It is also a pest of millets in India. [3]
The adult Aulacophora foveicollis measures 5 to 8 mm (0.2 to 0.3 in) in length and about 3.5 mm (0.14 in) in breadth. The colour of the elytra varies from pale orange-yellow to bright orange-red to medium brown, and the abdomen is black with soft white hairs. The grubs are found in the soil and are slender and creamy-yellow, with pale brown heads and prothorax. [2] [4]
A. foveicollis has a wide distribution across southern Europe, Asia, Australia and Africa. It is a serious pest of cucurbit crops in northwestern India. [4]
In northern India, the beetles hibernate over winter, emerging in March. After mating the female lays batches of about eight eggs in the soil. The eggs are orange and oval and hatch in one to two weeks. The grubs at first feed on leaf debris, roots and parts of the host plant in contact with the soil. They pass through four moults as they grow, and pupate in earthen chambers just below the surface of the soil. After a further week to two and a half weeks, the adult beetles emerge, climb the host plant and start feeding. The females start laying eggs within a week or so. There may be five generations over the course of the summer. [4]
The beetles are most destructive in March and April while the plants are small. They feed on the leaves, buds and flowers and can defoliate the plants; the grubs bore into the roots and damage the stems and fruits that lie on the soil. [4] A. foveicollis favours pumpkin (Cucurbita maxima) over other curcurbit crops, but will also feed on squash (Cucurbita pepo), melon (Cucumis melo), cucumber (Cucurbita sativus), watermelon (Citrullus lanatus) and the sponge gourd (Luffa aegyptiaca). [5] There are extrafloral nectaries on the sponge gourd which attract ants. The dominant species of ant in India and much of southeastern Asia is Camponotus compressus , and the presence of ants on the crop plant has a deterrent effect on A. foveicollis. [6]
The Cucurbitaceae, also called cucurbits or the gourd family, are a plant family consisting of about 965 species in around 95 genera. Those most important to humans are the following:
Luffa is a genus of tropical and subtropical vines in the pumpkin, squash and gourd family (Cucurbitaceae).
Gourds include the fruits of some flowering plant species in the family Cucurbitaceae, particularly Cucurbita and Lagenaria. The term refers to a number of species and subspecies, many with hard shells, and some without. One of the earliest domesticated types of plants, subspecies of the bottle gourd, Lagenaria siceraria, have been discovered in archaeological sites dating from as early as 13,000 BCE. Gourds have had numerous uses throughout history, including as tools, musical instruments, objects of art, film, and food.
Cucurbita is a genus of herbaceous fruits in the gourd family, Cucurbitaceae, native to the Andes and Mesoamerica. Five edible species are grown and consumed for their flesh and seeds. They are variously known as squash, pumpkin, or gourd, depending on species, variety, and local parlance. Other kinds of gourd, also called bottle-gourds, are native to Africa and belong to the genus Lagenaria, which is in the same family and subfamily as Cucurbita, but in a different tribe. These other gourds are used as utensils or vessels, and their young fruits are eaten much like those of the Cucurbita species.
Cucurbita pepo is a cultivated plant of the genus Cucurbita. It yields varieties of winter squash and pumpkin, but the most widespread varieties belong to the subspecies Cucurbita pepo subsp. pepo, called summer squash.
Cucurbita ficifolia is a species of squash, grown for its edible seeds, fruit, and greens. It has common names including Asian pumpkin, black seed squash, chilacayote, cidra, fig-leaf gourd, and Malabar gourd. Compared to other domesticated species in its genus, investigators have noted that samples of C. ficifolia from throughout its range are relatively similar to one other in morphology and genetic composition. Variations do occur in fruit and seed color, some isozymes, and photoperiod sensitivity.
Acalymma vittatum, the striped cucumber beetle, is a beetle of the family Chrysomelidae and a serious pest of cucurbit crops in both larval and adult stages. It is distributed from eastern North America to the Rocky Mountains. It is replaced in the west by Acalymma trivittatum, a duller species often with greyish or pale white elytra rather than yellow.
Diabrotica undecimpunctata, the spotted cucumber beetle or southern corn rootworm, is a species of cucumber beetle that is native to North America. The species can be a major agricultural pest insect in North America. Spotted cucumber beetles cause damage to crops in the larval and adult stages of their life cycle. Larvae feed on the roots of the emerging plants, which causes the most damage since the young plants are more vulnerable. In the adult stage the beetles cause damage by eating the flowers, leaves, stems, and fruits of the plant The beetles can also spread diseases such as bacterial wilt and mosaic virus.
Cucurbita foetidissima is a tuberous xerophytic plant found in the central and southwestern United States and northern Mexico. It has numerous common names, including: buffalo gourd, calabazilla, chilicote, coyote gourd, fetid gourd, fetid wild pumpkin, Missouri gourd, prairie gourd, stinking gourd, wild gourd, and wild pumpkin. The type specimen was collected from Mexico by Alexander von Humboldt and Aimé Bonpland sometime before 1817. In Latin, foetidissima means ill smelling.
Cucurbita maxima, one of at least five species of cultivated squash, is one of the most diverse domesticated species. This species originated in South America from the wild subspecies Cucurbita maxima subsp. andreana over 4,000 years ago. Cucurbita maxima, known for modern varieties as Hubbard, Delicious, Marblehead, Boston Marrow, and Turks Turban, originated in northern Argentina near the Andes or in certain Andean valleys. Secondary centers of diversity include India, Bangladesh, Myanmar, and the southern Appalachians.
A pumpkin, in English-language vernacular, is a cultivated winter squash in the genus Cucurbita. The term is most commonly applied to round, orange-colored squash varieties, though it does not possess a scientific definition and may be used in reference to many different squashes of varied appearance.
Aulacophora is a genus of beetles in the family Chrysomelidae, commonly known as pumpkin beetles; some species are pests of agricultural crops. The genus was named in 1836 by the French entomologist Louis Alexandre Auguste Chevrolat, in Dejean's Catalogue des Coléoptères. The name, from Ancient Greek, signifies "furrow-bearer"' from aulax, "furrow".
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. This is native to South America and is now distributed in Central America and other global areas.
Cucurbita argyrosperma, also called the cushaw squash and silver-seed gourd, is a species of winter squash originally from the south of Mexico. This annual herbaceous plant is cultivated in the Americas for its nutritional value: its flowers, shoots, and fruits are all harvested, but it is cultivated most of all for its seeds, which are used for sauces. It was formerly known as Cucurbita mixta.
Cucumber beetle is a common name given to members of two genera of beetles, Diabrotica and Acalymma, both in the family Chrysomelidae. The adults can be found on cucurbits such as cucumbers and a variety of other plants. Many are notorious pests of agricultural crops. The larvae of several cucumber beetles are known as corn rootworms.
Peponapis pruinosa is a species of solitary bee in the tribe Eucerini, the long-horned bees. Its common name is the eastern cucurbit bee. It may be called the squash bee, but this name can also apply to other species in its genus, as well as the other squash bee genus, Xenoglossa. This bee occurs in North America from the East Coast of the United States to the West Coast and into Mexico. It is an oligolege, specializing on a few host plants, the squashes and gourds of genus Cucurbita. Its range expanded as human agriculture spread throughout North America and squash plants became more abundant and widespread. It may also have spread naturally as the range of its favored wild host plant Cucurbita foetidissima expanded.
Coridius janus, sometimes known as the red pumpkin bug, is a species of bug in the family Dinidoridae. It feeds by sucking on the sap on soft parts of plants especially in the cucurbit family and causes damage to crops.
Myllocerus discolor, commonly known as mango ash weevil, is a species of weevil found in India, Sri Lanka and Myanmar. The Sri Lankan population is identified as the subspecies, Myllocerus discolor canescens.
Henosepilachna septima, is a species of lady beetle found in Vietnam, Indonesia, Malaysia, India, Sri Lanka and Pakistan.
Aulacophora hilaris, also known as Pumpkin Beetle, Banded Pumpkin Beetle, Pumpkin Flea Beetle or Spotted Pumpkin Beetle, is a beetle in the genus Aulacophora that is found in Australia.
