According to the survey of ministry of agriculture of Egypt, the mango and guava trees occupy 102352& 30431 feddans, respectively producing about 325465 & 228814 tons mango and guava fruits, respectively. Due to the great damage can be done by the scale insects not only by sucking the plant sap that give low photosynthesis and respiration, which leads to curling, yellowing, dropping to leaves, so malformation, dwarfing and decreasing fruit production ( quality and quantity ),even plant death; but also

caterpillar is ringed with yellow, black, and white on each segment and has a pair of black fleshy tubercles at each end (Emmel, 1999). Monarchs smell with their antennae while they taste with their feet (Wexler, 1994). While the male monarchs have scent scales on their wings and "hair pencils" on their abdomens which secrete a scent (Emmel, 1999). The male scent is used during mating. The copulation of a male and female monarch can last from thirty to sixty minutes which is about average for most butterflies
Research Project: Class Insecta Insects are invertebrates in the class Insecta from the phylum arthopoda. Arthropods include more than 850,000 species and form by far the largest phylum in the animal kingdom, exceeding in number all the other Phyla combined. The characteristic tough exoskeleton and jointed limbs are superimposed in a segmental body plan that reflects the evolution of arthropods from ancestors of the annelid worm. Insects, arachnids, myriapods and crustaceans are the major groups
Insects have an enormous population in our planet and are being studied in the field of entomology. A single insect would be able to show the beauty our planet has. Many of the insects are considered threats and pests but a lot of them are also beneficial. If we would like to utilize these creatures, we should be able to have an outlook of how an expert in this field view insects- in the view of an entomologist. Entomology is like a gateway discipline to many other areas of the biological sciences
work of bees. Additionally, outside of the farm, many wild plants are also dependent on bee pollination to produce their wild berries and fruits. The berries and fruits provided by the wild plants are a necessary food intake for animals and other insects in the corresponding ecosystem. Unfortunately, there has been
entomophagy: the practice of consuming insects as a food source. The consumption of insects is not a completely foreign concept, with archaeological evidence dating back several thousand years demonstrating that the human diet originally featured insects (Huyghe, 1992). In fact, many societies in Africa and South America still incorporate insects as a crucial part of their diets (Huyghe, 1992) - and there is no reason for Australia to be an exception. Insects are exceptionally nutritious and particularly
Insect Lab Report The class insect has the same body structures and functions. They have a segmented body divided into three parts, head, abdomen and thorax. They also have an antenna, segmented legs, and wings. The functions of the body parts, however differ from the different orders of insects. For instance the mouth parts for an adult ladybird beetle is chewing, but on a Hemiptera the mouth form is a beak called the stylets as is the case with an aphid. Palps are on the ends of beetle’s mouth
small dark figure that is colored by white markings and banded legs. Its proboscis or snout is mostly black with regard to the white palp tips (Russel 1996). The dorsal pattern of white scales on the scutum is in the shape of a ‘lyre’ with two central based stripes that contrast with the dark scales present on the insect (Womack 1993, Russel 1996). Its wings are dark scaled and femur and hind legs are pale scaled for about three-quarters, and dark scaled for about two-thirds (Russel 1996). The first
The Life Cycle of a Butterfly The life cycle of a butterfly is perhaps one of the most beautiful and astounding processes in nature. The four stages a butterfly goes through to become the beautiful flying insects are just as interesting as the vibrant colors and patterns on the wings of the various species of butterflies. The four stages are as follows: the egg, the caterpillar, the pupa, and the emergence of the butterfly. Each stage is vital to the development of the adult butterfly. Perhaps the
Legislators have defined "salvage logging" as the act of logging unhealthy forest stands, considered to have a probability of experiencing extreme insect and disease infestation of catastrophic fire. However, no scientific consensus exists for describing an unhealthy forest, predicting or classifying catastrophic fire event, or classifying the resultant damage of an insect and disease. Salvage logging was an alternative way of meeting timber demands and generating revenues by timber industries and legislators
desired characteristics. In the early 1990s, the first biotech food on the market was a tomato that ripened on the vine and could be transported without bruising. The products of agricultural biotechnology today include plants that are protected from insects or are tolerant to herbicides. Biotech foods have now made their way onto our tables. More than a third of the corn and more than half of the soybeans in the 1999 U.S. harvest were grown from seeds produced using biotechnology. As biotechnology crops
an unpleasant consequence. (See References 1) Leaf Scorch Disease Leaf scorch is a disease that's caused by the bacteria Xylella fastidiosa. Mainly found in California, this disease is spread from infected plants to health ones by 1/2-inch-long insects known as glassy-winged sharpshooters. When an oleander is infected, the transportation of nutrients and water from the roots to the leaves is blocked. This causes yellowing of the leaves from the tips inward, followed by drooping and eventually death
for cracking seeds. Some had long, sharp beaks, useful for prying insects out of their hiding places. Some had long tail feathers, others short ones. Darwin took copious notes, captured insects and animals and selected plants. These he preserved in jars and took them back to England where he thought about the implications of what he had seen. for almost three decades. What occurred to him was a simple notion: animals, plants, insects, fishes, etc., which were obviously related differed slightly and
The global population of bees is dramatically declining. Hundreds of bee species in North America are headed for extinction. In the United States alone, from Aprils of 2015-2016, beekeepers reported a 44% loss of their colonies, and that number is higher (more than 50%) in countries like Belgium, France, Netherlands, Greece, Italy, Portugal, Spain, Switzerland, and Germany. The situation is worst in China, the largest producer of honey in Asia, where wild bees are dramatically declining, forcing
disappearing from a hive or the finding of all bees dead in and around the hive. With the current need for more and more pollination of places like California almond fields we need more bees. From this type of pollination we have developed large scale commercial beekeeping. So with many beekeepers having to send their bees to these large pollination zones we are allowing bees to be covered in pesticides and the bringing back of pollen from flowers or plants that have been sprayed are being connected
The disappearance of honey bees is baffling scientists everywhere. Although most people see bees as useless annoying insects, they play an important role in the eco-system. Without bees, agricultural business would cease to exist, so it is vital that bees are saved. Currently, about one-third of the honey bees on the United states have disappeared. It seems that within a few days of having a good, healthy colony of bees, most of the adult population disappears. They can't even find any bodies near
To most, the honeybee can be an annoying insect that has a powerful sting. Yet, the honeybee is so much more than just another insect. The honeybee is arguably the most vital component in the development of our food crops. With roughly 90 percent of our food crops dependent on the pollination of our honeybees, our food system, agricultural development, and diet rest on the work and well being of these buzzing insects. Unfortunately, since 2006 there has been a major decline in the population of honeybees
may as well be classified as the single most common seasoning on our food today. Most of the food we eat is marinated with over one-billion tons of pesticides annually by farmers across the world (Alavanja). Their special blend helps kill or repel insects from eating crops, which preserves a ton of crops that would have died otherwise. The benefit of savings these crops are great in number: there is more food to go around, farmers can sell more crops, and the surplus of food drives down prices. Pesticides
In nature, every advantage increases an animal’s chance of survival, and therefore its chances of reproducing. This fact has caused many animals to evolve numerous adaptations to help them survive. Some animals have gained the ability to conceal themselves by any means necessary. This ability is called camouflage. The ability to camouflage is a result of natural selection and evolution. Camouflage is an important trait that some animals have gained which allow them to be better fit for their environment
