Henosepilachna septima, is a species of lady beetle found in Vietnam, Indonesia, Malaysia, India, Sri Lanka and Pakistan.
Body length of male is about 6.62 mm and female is 7.44 mm. Body highly convex and yellowish red in color. Elytra consists mostly with 28 spots. Head lacks any spots. Pronotum mostly 2 and 6 spotted, but sometimes 4 and 7 spotted. The spot 7 is hazy. Elytral spot pattern variable. All the spots are away from suture and margin. Postcoxal line is complete and subterminal. In male genitalia, phalobase is trabe and basal piece is normal. Parameres are long, and thick without a distinct apical thorn, but covered with short hairs on apex. Siphonal tip is compressed. [1]
Adults are abundant during August and September. [1] Adult female lays about 9 to 46 clusters of eggs. The incubation period varied from 4 to 6 days. Grub period is about 12 to 15 days, and pre-pupa is 1 to 2 days. The pupal period extends from 3 to 4 days, and the pre-ovipositional period is about 6 to 8 days. The total life cycle of the beetle is about 22 to 26 days, whereas the lifespan of adult is 16 to 25 days. [2] A herbivorous ladybeetle, it is a serious pest of cucurbits where both grubs and adults feed throughout the crop stages and results in skeletonising the leaves.[ citation needed ] The recorded host plants are Momordica charantia , Luffa aegyptiaca , Luffa acutangula , Trichosanthes dioica and Trichosanthes cucumerina . [3] The presence of grub indicates by scrapping nature of the epidermis, while semicircular cuts in rows, indicates the adults. [4]
Trichosanthes dioicaRoxb., also known as pointed gourd, is a tropical perennial cucurbit plant with its origin in the Indian subcontinent. It is also known as parwal, palwal, potol, or parmalin in different parts of India and Bangladesh. The plant propagated vegetatively and grows with training on a support system as pencil-thick vines (creepers) with dark-green cordate (heart-shaped) simple leaves. It is a well-developed dioecious plants having distinct male and female flowers on staminate and pistillate plants, respectively. The fruits are green with white or no stripes' and have unpalatable seeds. Size can vary from small and round to thick and long — 2 to 6 inches. It thrives well under a hot to moderately warm and humid climate. The plant remains dormant during the winter season and prefers fertile, well-drained sandy loam soil due to its susceptibility to water-logging.
Trichosanthes cucumerina is a tropical or subtropical vine. Its variety T. cucumerina var. anguina raised for its strikingly long fruit. In Asia, it is eaten immature as a vegetable much like the summer squash and in Africa, the reddish pulp of mature snake gourd is used as an economical substitute for tomato. Common names for the cultivated variety include snake gourd, serpent gourd, chichindapadwal and Snake Tomato.
The Mexican bean beetle is a species of lady beetle that can be an agricultural pest. It is one of the few North American lady beetles that feed on plants rather than other insects. It is found throughout Mexico and the eastern United States, and is abundant in the wetter and more heavily irrigated areas west of the Rocky Mountains. It does not tolerate extremely dry areas.
Coccinellidae is a widespread family of small beetles. They are commonly known as ladybugs in North America and ladybirds in the United Kingdom; "lady" refers to mother Mary. Entomologists use the names ladybird beetles or lady beetles to avoid confusion with true bugs. The more than 6,000 described species have a global distribution and are found in a variety of habitats. They are oval beetles with a domed back and flat underside. Many of the species have conspicuous aposematic (warning) colours and patterns, such as red with black spots, that warn potential predators that they taste bad.
Henosepilachna vigintioctopunctata is a species of beetle in the family Coccinellidae. It is commonly known as the 28-spotted potato ladybird or the Hadda beetle. It feeds on the foliage of potatoes and other solanaceous crops. It was previously called Epilachna vigintioctopunctata and is a cryptic species complex. It is very often confused with a closely related species, Henosepilachna vigintioctomaculata, which occurs in Russia, China, Japan, and Korea, and is given the same "common name".
Coleomegilla maculata, commonly known as the spotted lady beetle, pink spotted lady beetle or twelve-spotted lady beetle, is a large coccinellid beetle native to North America. The adults and larvae feed primarily on aphids and the species has been used as a biological control agent. Based on name connotation and to avoid confusion with other species also called "spotted ladybeetle", spotted pink ladybeetle is probably the most appropriate common name for this species.
The Epilachninae are a subfamily of the family of lady beetles, the Coccinellidae, in the order Coleoptera. Superficially, they look much like other ladybirds in the larger subfamily Coccinellinae, but they differ importantly in their biology, in that the members of the subfamily are largely or completely leaf-feeding herbivores rather than being predators. Accordingly, several members of the subfamily are crop pests, and sometimes cause locally serious crop losses.
Pediobius foveolatus (Crawford), is a tiny exotic parasitoid wasp that is used for biological control of Mexican bean beetle, Epilachna varivestis, an important insect pest of snap beans, lima beans, and sometimes soybeans mainly found at economic levels in the eastern United States. Pediobius foveolatus is in the family Eulophidae, and is the most successful biological control agent for Mexican bean beetle. This wasp only attacks beetle larvae, not eggs or adults. It is commonly used by smaller, organic growers; but is also mass released throughout the state of New Jersey, by their state department of agriculture.
Henosepilachna vigintioctomaculata is a species of beetle in the family Coccinellidae. It is commonly known as the 28-spotted potato ladybird, a name also used for the closely related species, Henosepilachna vigintioctopunctata.
