Larva

Whenever one get a dog or a cat one likes to play and have fun but sooner or later they will probably get fleas. These little pest can cause itching to someone’s pet and they can develop tape worms in the animal’s intestines if the flea infestation is not taken care of. Fleas are also thought to be responsible for the bubonic plague. This annoying parasites effects it host in some cases transmitting disease. To get the parasite off the host dawn dish soap kills the parasite and its eggs. If the…

Orientia tsutsugamushi bacterium, the causeitive agent of Scrub Typhus disease. The pathogen is spread by some species of the family of Trombiculid mites; there are four defined stages in the life cycle of the mites, the egg, larva, nymph and adult stage. The larval stage (Chigger mite) is the only this stage that feeds on a host, thus transferring the O. tsutsugamushi bacterium to the human host. Nymphal and adult Trombiculid mites live in the soil and feed on the eggs of insects. Humans are an…

Manual. One-part Drosophila medium was deposited into the bottom of the culture vessels with one-part water. Then the medium was left to firm. Once the medium was firm, the yeast was added as a food source to sustain development, medium is for the larva to eat, and yeast is for adult flies to eat. A piece of plastic mesh was added to the culture vessel to give the fruit flies more surface area, which was needed so that they would not crush one another or get stuck in the medium. To sex the fruit…

fields, picking berries, or even gardening. Summer is also the height of bug season. One nasty rascal that makes itself known to those who enter into many forests, grassy fields, or parklands near water is the chigger. The chigger is actually a mite larva. Each chigger is only 1/150th of an inch long and can barely be seen. The results of their bites don't require a magnifying glass, however. Contrary to popular belief, chiggers do not dig into the skin. Instead, they jab the soft areas of…

Adaptations Adaptations are features of an organism which allow it to survive in its niche, ultimately allowing it to reproduce. Adaptations can be structural, behavioural or physiological. Structural adaptations are physical features of an organism, behavioural is something the organism does and physiological adaptations are chemical processes an organism uses to survive. Each adaptation an organism has, has a purpose to help it survive in its niche. Green Chiton The Green Chiton has…

Do you want me to tell you about a gorilla who got shot in a zoo species? Well guess what you're in luck. I’m talking about the western lowland gorilla. They have the same fingerprint as us but also unique nose print. According to National Geographic's, it states that these animals stand at 4-6 ft (1.2-1.8 m) and weigh 150-400 lbs. They have brownish-gray hair. They’re small yet strong. Again according to National Geographic's males are more aggressive and males are known as silveracks. And…

According to Butz and Hayden (2014), the durations of the egg, larva, and pupal stages remain constant regardless of the parents age but the number of offspring produced by the parent would be greatly decreased which could lead to a lower number of results due to the lack of flies being produced. D. melanogaster have…

In recent years, primarily beginning in 2005, the abandonment of hives, massive deaths within colonies themselves, and significant losses of entire populations of A. mellifera have been reported (Callahan 2014). This massive disruption in the population of A. mellifera is known as Colony Collapse Disorder, and the cause is multifactorial. Two underlying causes of Colony Collapse Disorder are disease and malnutrition, but are not the primary reason for the massive death tolls observed in the…

factors poses a serious problem for humans. Because humans are the incidental host of this parasite, third-stage larvae can have devastating effects on the body. Of the three parasites discussed, raccoon roundworm is most often associated with neural larva migrans, a severe disease that affects humans. Children in particular are commonly infected with this helminth (see Figure 1). This is possibly because they explore their world orally. Raccoons are known to defecate in shared spaces known as…

As kids or even now as adults we worry so little of contracting infectious disease, we do not realize that our environment is home to numerous of organisms that are harmful. For example, a single bite of a bug such as a tick can completely change your life. A tick bite can potentially lead to Lyme disease, which can become a severe illness. According to Sanjuna (et al 2018) “about 300,000 new cases per year are recorded world wide” (p.1) turning into the leading cause of tick borne diseases.…
