Bark beetle

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 them from burrowing. Once a tree becomes infected, the rate of infestation for that tree will increase dramatically. As the first larva grows and reproduces, more and more beetles with burro into the tree, eventually causing death to the tree. Bark beetles…

Bark beetle outbreaks are often fueled by drought and fire-damaged trees, killing more trees and exacerbating the effects of climate change (CFPC 2015). This paper will be focusing on the decline of one of California’s most abundant species, the Ponderosa pine (Pinus ponderosa). Ponderosa pine trees have a wide range and can be found throughout the western United States, southern Canada, and northern Mexico (Little 1971). Here in California they primarily occupy mountainous regions but have…

The polyphagous shot hole borer (PSHB) problem, originated in Asian countries, shifted from a decayed and rotting host of trees in south east Asian countries to native, nursery, fruit, and landscape tree hosts in southern California and Israel. The boring beetle and tree host could exist mutually, however, the distinct symbiotic relationship between the invasive ambrosia beetle Euwallacea and the destructive fungi Fusarium poses a potential lethal threat to specific host trees, such as avocado…

Look for branches breaking near the trunk, slits in the bark, woodpecker injury and chewed on foliage on ash trees. “EAB can wreak havoc in your cemetery, causing huge risk and budgetary issues. Spot EAB warning signs early. Or, you risk losing 15 to 30 percent of all the trees on your property within 3 to 5 years,” cautioned Borkowicz. If you spot a tree risk, call a trained arborist for help. “Preventive tree care can save thousands of dollars in potential damage or tree removal later on,”…

Malicious A twisted tree trunk protrudes out of the silt like earth, covered in crude knots and lanky dead branches; the trunk hovers over the small stretch of land it sits upon. The rough, callous bark of the foreboding tree a dark hazel splattered with sections of sunken grooves. A shadow casts upon the intruding tree, darkening the bottom section of the once splendid trunk to a sinister shade of black. The upper top half on the trunk splintered, as if its own structure and size had betrayed…

Walking down the trail the branches covered in leaves were close enough to tickle my shoulder. Flowers of bright, vibrant colors were everywhere. I could see red, pink and blue colors, it was as if I was looking at a rainbow, but-they-were-flowers. Suddenly this amazing sweet smell entered my nose, the smell turned into a taste that made my mouth water, what is that? Kiwi, my scented hand lotion, it is Kiwi hand lotion, the smell is adding to the beauty that surrounds me. Why are all these…

Somewhere in the Atlantic Ocean, the Jet Stream II floats tranquil in the clear blue waters. The scorching sun lends its warm rays to the peaceful scenery that captures the region. The Jet Stream is no ordinary yacht; you won't see this listed in Yacht World or Ships for Less. A sixty-foot monstrosity with a price tag of twenty-five million and climbing, a one of a kind prototype constructed exclusively for the United States Government as a chameleon spy ship. Complete with all the bells and…

Rickie Williams Zoology Ms. Julie Lady Bugs (Coccinellidae) Research paper Introduction Lady bugs are a part of the Coleoptera order. According to University of Arkansas, United States department of Agriculture and County Governments Cooperating Coleoptera is identified by two pairs of wings; front pair hard and shell-like, and hind pair is membrane like. Their mouth part is chewing and their metamorphosis is complete. According to Turkish Journal of Zoology Lady bugs are predator insects. They…

oxygen and consume carbon dioxide. If the trees are killed by the fires, it can lead to a rise in carbon emission, since there are no trees around and burning trees can also cause the release of carbon dioxide. The more greenhouse gases the trees release will in turn to create stronger effects for the global warming. Second of all, the insect outbreak is also affected by global warming. The survival of insects and diseases is largely depend on climate. Due to the warmer and wetter conditions by…

Adaptations allow certain animals to live in certain environments/habitats, these adaptations are crucial for the survival of an organism. Group 2 - Insects Insects are able to survive on land or in water. Both land insects and aquatic insects do the same gas exchange process however both have different adaptations that allow them to live in either land or water. A diving beetle and a mayfly are both good examples of how insects have adaptations that allow them to live in the water and be fully…
