Invasive Species Position Paper Grading Rubric Essay

Invasive Species Position Paper Grading Rubric - Essay Example subsequently these AHBs were found in Arizona, California and Southern parts of United States.AHBs argon more adaptable to equatorial regions where the abundance of flora is dependent on unpredictable rainfall. As an adaptability to this factor AHBs they frequently swarm to new-fangled habitats, reproduce rapidly with shorter developmental life cycles and survive even on sparse supplies of pollen and nectar.Economic brat Essential need for honey bees to pollinate crops as well as honey production is the government issue of great economic concern. Americans are retiren to consume about 275 million pounds of honey every year. In this context AHBs produce little honey and wax when compared to EHBs. They also produce less wax affecting the manufacture of candles, polish and floor wax. Due to frequent swarming and extensive hive abandoning nature they are less preferred in managed beekeeping industry.Ecological threat i) They compete and displace local EHBs and other pollinators for nectar and pollen. ii) AHBs invade EHB hive and are capable of upsurging the hive and replacing the EHB milksop. In a single coevals the EHB matriline is eliminated and the entire EHB hive being Africanized (DeGrandi-Hoffman 2006). iii) Studies of DeGrandi-Hoffman (USDA 2004) hold in shown that when EHB queens were inseminated with equal proportions of African and European drone sperms, the EHB queen preferred African sperms, producing on an average of about 70% AHB offspring. These factors may eventually decrease the abundance of other bee species which affects pollen harvest and reduce EHB progeny.Social threat AHBs are more aggressive and sting in greater number on less provocation and respond to any disturbances such as ratty noises, strong odors around the hive. They are able to sense threat within 100ft and track upto 1/ fourth a mile. A sting of a single bee releases a pheromone which stimulates other bees to agitate and attack. The sting of AHBs is know to cause anaphylactic shock. The venom of the bee triggers the release of histamine which can lead to vasodilation and loss of blood pressure. If the condition is not reversed within short time it may lead to death of the person due to shock. Methods of containAHBs are better pollinators when compared to EHBs as they emphasize on brood rearing and growth of the colony preferably than honey production. Hence their complete elimination is not a wise option. Agricultural Research serve scientists along with groups like the American Beekeeping Federation, the American Honey Producers Association and the Apiary Inspectors of America have been entrusted with the job of finding the solution to the problem of AHBs in US. Two popular basic methods of control arei) Drone flooding By limiting the possibility of Africanized drones mating with Europeans queens where commercial reared queen bee has a chance to mate with common honey bees.ii) Re queening replacing queen of
