Larva

is what is passed down to an organism’s offspring. This gene could change a trait that helps an organism to survive (Dorken et al. 2016). For example a bird’s beak may be longer or shorter depending on how they can attain food in the location they reside. Natural selection has different branches to it; the one studied in this lab is called directional selection. Directional selection is when an extreme phenotype is favoured over other physical alleles (Reece). The directional selection that may be present within this study is if gall size determines if the larvae is dead or alive. Gall flies lay their eggs at the tip of goldenrod shoots which hatches into the larva during the summer. The larva bored into the plants stem and begins forming a gall. The galls reach their full size at the end of the summer while the larva matures throughout the year. This is when predators start to attack the goldenrod and feed on the fly larvae within the gall. These predators include parasitoid wasps (Eurytoma gigantea and E. obtusiventris), the beetle (Mordellistena unicolor) and birds specifically the downy woodpecker and black-capped chickadee. The parasitoid wasps attack during the summer months. The female wasp uses her ovipositor to lay her eggs within a hole in the gall originally made by the fly larvae. The wasp larvae then feed on the fly larvae and continue to reside in the gall. If the gall is too thick the ovipositor will not be able to make it into the gall to lay eggs. The…

Nothing can ruin a sunny afternoon quite like the incessant buzzing of mosquitoes. More than just obnoxious, they can bite you repeatedly, resulting in several days of itching and discomfort. Alabama summers provide the perfect opportunity to spend time outdoors, but many homeowners are kept from doing so by countless, pesky mosquitoes. Since knowledge is power, here is some quick information to help you win the fight against this nuisance. What Types of Mosquitoes Are in Alabama? Thanks to…

Mosquito Magnet Trap Placement Mosquito traps have proven that they can be effective at eliminating most mosquitoes as well as other flying insects. However, that does not mean that everyone who purchases a mosquito trap is 100% satisfied with the way it performs. In most cases, their issues could be solved if they simply take a look at where their trap is located. In order to have the trap work as well as it can, you need to make sure you understand the right Mosquito Magnet trap placement. Why…

The Beauty of Complete Metamorphosis It was a warm day in early October. A young boy at the age of 11 with pale skin and freckles was frolicking in his neighborhood park about a block away from his house. He wore his favorite pair of blue jean overalls with a yellow and olive striped shirt underneath. He loved being outside and spent most of his time at his neighborhood park. His normal routine after he got off the bus from school was to go home, eat a snack of some sort, change into his play…

Even when the beauty surrounded me, The mosquitos would not forget about the scent, I then looked like a huge walking mosquito bite. The mosquitos gave me what felt like millions of bites even though there were probably at least 50. When the mosquito attached to my arm it felt like a paint brush swiping against my arm. Why do mosquitos and gnats have to be alive? I would be a lot more comfortable hiking right now if they were not living. The mosquitos and gnats were attacking me probably because…

Area Found: This pill bug was found on campus, under a few rocks along the sidewalk. There were multiple specimens found in the same area. It was living in dirt on a rainy night. Habitat: Native to the Mediterranean and since introduced all over the world. They prefer the moist environments because of a waxy outer covering that does not allow them to retain water. Diet: They mostly eat the decomposing plant materials and seeds. A. vulgare can also feed on the roots of garden vegetables such…

There are several different kinds of arthropods that feed off of and find nutrients from blood. These kinds of arthropods are also called “hematophagous,” or “bed bugs.” In this experiment, the researchers attempted to distinguish which chemicals would most effectively initiate and persuade feeding in different parts of a bed bug’s life. Various feeding stimulants, such as ATP, ADP, and AMP were used in a feeding system. Of these stimulants, it was found that the most effective chemical in…

This verse, pregnant with mystical symbolism, further expands the theme discussed in the preceding and the fourteenth verse of this granth. The said two verses speak of the transformation of the self from its base state to a state of true and perfect awareness, while this verse, using the metaphor of the metamorphosis of a larva into a fully-grown wasp, speaks of the extinction of the individual self and attainment of oneness and identification with the Nūr of the Satguru. It is a biological…

While feeding on nectar, they pollinate many types of wildflowers and make our fruits. The monarch butterfly is known by scientists as Danaus plexippus, which in Greek literally means "sleepy transformation." The name evokes the species' ability to hibernate and metamorphize. There are four stages in the life cycle of a butterfly. A monarch begins life as a single, greenish egg attached to the underside of a milkweed leaf. The `worm-like larva grows inside the egg. When it is ready, the larva…

study the effect of the concentration of the chemical solution on the heartbeat of the zebrafish larva. There are many advantages in using the zebrafish as the model organism. According to Gore, Monzo, Cha, Pan and Weinstein (2012), the zebrafish is commonly used as the model system of the vertebrate as it has small in size and also have the rapid development in their life. This is one of the reason of the chosen of the zebrafish as the excellent model organisms that widely being used in…
