Beetle

Flea beetles are pest of brassicaes, creating holes in the leaves and stems of seedlings. The seedlings are highly attacked as soon as they surface above the ground level and the damage of these beetles are very pronounced on young plants and even cause plant death. Some flea beetles are general feeders, others attack only particular types of plant. The flea beetle has a narrow host range to plants primarily in the brassicaceae. Most of the flea beetles prefer cruciferous plants which produce…

Few studies on the biology and life cycle of bostrichid beetles have been done with mostly concentrating on economically important species (Liu et al., 2008). Typically, the bostrichid beetle undergoes complete metamorphosis with four life stages – egg, larva, pupa and adult. Eggs are laid in crack and cervices of sawn lumber or logs. Larva hatch and bore ¼ inch into the wood. Tunnels are filled with tightly packed, fine sawdust-like materials. Pupation happens at the end of the tunnel. Once…

that have not been able to develop adaptations to cope with them. One of the most dangerous invasive species is the Asian Longhorned Beetle, which infests a variety of hardwood trees in North America and Northeastern Asia. The Asian Longhorned Beetle originates from China and Korea, but was first discovered in the United States on Long Island in 1996. This Beetle spends its most destructive period when it’s in its larval stage, where it burrows deep within the bark of a tree and feeds on the…

Whether about organisms or the earth itself, humans learn new material that will benefit them in some way. Famous scientist and advocate for wildlife conservation, Jane Goodall argues that the American Burying Beetle is “nature’s most efficient recyclers,” (Goodall 63). The beetle helps decompose animals, which makes the ground rich and full of nutrients, excellent for plants. This insect may seem “gross” or “disgusting”, but in reality it helps our environment in an enormous way (Goodall).…

According to TheRefugeeProject.org in 1994 the number of refugees displaced in their country or having fled inernationally took a turn to “over 15,000,000”. Mawi Asgedom was one of these refugees that experienced a lot of struggles. In the memoir Of Beetles And Angels Mawi tells his own difficult but inspiring true story of being born in Ethiopia having to leave to go to a refugee camp in Sudan because of war and then fleeing to America at only the age of 7 years old. Mawi overcame the obstacles…

The green thistle beetle or tortoise beetle, Cassida rubiginosa (Coleoptera: Chrysomelidae) is a leaf feeding beetle that belongs to the subfamily Cassidinae (hereafter Cassida), is with a green dorsal surface with yellowish elytral margins and black underneath. It can be found in Europe, the United States and Canada (Asadi et al., 2013). It feeds primarily on California thistle, although it is an oligophagous/ phytophagous feeder (Cripps, 2013, Fujiyama et al., 2011). This beetle was well…

Male Bean Beetle (Callosobruchus maculatus) Reproductive Success Abstract: Callosobruchus maculatus is a bean beetle that lays eggs on the surface of beans, the larvae hatch out of the eggs and immediately burrow into the bean to devour all its nutrients and mature into an adult. The study of the male’s reproductive success when given access to water versus no access could lead scientists down a path of slowing the growth of the bean beetle population. The study was performed in lab 201…

A forest becoming infected with bark beetles is a negative occurrence from both human and ecological perspectives. Bark Beetle is the common name for more than 600 species of beetles whom burro into the trunks of trees and lays their eggs. Once the eggs hatch the larva will feed on the living tissues inside of the tree and then eventually lay their eggs and begin the cycle over. The beetles tend to strike during drought years when the trees are vulnerable and cannot produce much sap to protect…

Living the life I live today, I could not imagine having to live off of goat milk, eggs, UN rations, or whatever I could grow along with getting brutal beatings in and outside of school. In Of Beetles and Angles by Mawi Asgedom, it tells the story of Mawi and the difficulties, hardships, and experiences that he faces in the refugee camp in Umsagata, Sudan in the early 1980's. In differeation to my life, Mawi had to experience a lot of difficulty in the camp; there were brutal beatings in and out…

by ravenous Japanese beetles who eat every plant in sight. If you lived in America prior to 1912, you wouldn't have to imagine this scenario because you would be living it. As their name suggests, Japanese beetles (Popillia japonica) are native to Japan. The water surrounding the island and the insect's natural predators kept them contained there until the fateful day that a plant was shipped from Japan to the United States. Hiding in the soil of this plant were Japanese beetle grubs, who…
