Diabrotica barberi, the northern corn rootworm, is a species of skeletonizing leaf beetle in the family Chrysomelidae. It is found in North America. [1] [2] [3] Adults feed on corn, and, when corn is unavailable, goldenrod pollen. [4]
There are many similarities in the life cycles of the northern and western corn rootworm. Both overwinter in the egg stage in the soil. Eggs, which are deposited in the soil during the summer, are American football-shaped, white, and less than 0.004 inches (0.10 mm) long. Larvae hatch in late May or early June and begin to feed on corn roots.
Spotted cucumber beetle, northern corn rootworm beetle, and western corn rootworm beetle Western corn rootworm. Cucumber beetle is a common name given to members of two genera of beetles, Diabrotica and Acalymma, both in the family Chrysomelidae. [1] The adults can be found on cucurbits such as cucumbers and a variety of other plants. Many are ...
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.
Diabrotica is a large, widespread genus of beetles in the family Chrysomelidae. Members of this genus include several destructive agricultural pest species, sometimes referred to as cucumber beetles or corn rootworms.
However, Western corn rootworm adults are longer than striped cucumber beetle adults. Whereas the length of the adult striped cucumber beetle is around 5.25 mm, the length of the western corn rootworm is around 6.3 mm. [ 3 ] Furthermore, the black stripes of western corn rootworm adults do not fully span across the entire elytra, but begin to ...
In aboveground communities, EPNs have few side effects on other animals. One study reported that Steinernema felidae and Heterorhabditis megidis, when applied in a range of agricultural and natural habitats, had little impact on non-pest arthropods. Some minimal impacts did occur, however, on non-pest species of beetles and flies (Bathon 1996).
Andersonstrongylus milksi (syn. Filaroides milksi) is a rare member of the Filaroididae in dogs and is largely similar to Filaroides hirthi in appearance, life cycle, and clinical presentation. [36] The parasites cause small nodules in the area of the bifurcation of the trachea or in the lung tissue; dead worms can also cause larger granulomas.
