Summarizing a biological article - Essay Example

SUMMMARIZING A BIOLOGY ARTICLE The study was set to determine whether Access Sugar-fermenting yeast can be a source of an organic’s carbon dioxide which can attract Anopheles gambiae mosquitos that causes malaria. The study was conducted since2001. Renate C Smallegange, Wolfgang H Schmi, Karel J van Roey, Jeroen Spitzen, Niels O Verhulst, Wolfgang R Mukabana and Willem Takken conducted the study at(ICIPE) Mbita western Kenya (Verhulst 28).Carbon dioxide was found to plays an important role in the host and seeking process of opportunistic, anthropophilic and zoophilic mosquito species.

It is, therefore, added to tools of sampling mosquitos. The study investigated whether CO 2, supplied from gas cylinders could be replaced by CO 2 derived from fermenting yeast. Trapping experiments targeting of gambiae s.s. Mosquitos species were conducted in the laboratory for both semi-field and field (Verhulst 28).The main purpose of the study was to answer if: CO 2 derived from fermenting yeast replace that supplied from supplied from gas cylinders in catching mosquitoes? (Verhulst 28).

Change in CO 2 concentrations in MM-X trap baited affects the number of mosquitoes trapped? And which one of the MM-X traps recorded a significant number of mosquitoes?The main experimental approaches used were field and laboratory tests. In these methods, it was found that more mosquitoes were recorded in the baited trap with CO 2 produced by yeast than in unbaited trap.MM-X trap was baited with volatiles produced by mixtures of sugar, water and yeast in 25 L bottles (Verhulst 28). Comparisons of Catches were done with traps baited with industrial CO 2.

Human odors were also examined as an additional effect. In the semi-field facility and laboratory dual-choice experiments were performed. The test showed that the yeast-produced Carbon dioxide on mosquitoes’ number entering an African house was carefully studied in the Malaria Sphere. The results of these methods recorded that, Traps baited with yeast-produced CO 2 trapped a significant more mosquitoes than traps baited with industrial CO 2 and unbaited traps, both in semi-field the laboratory.

Adding yeast-produced CO 2 to traps baited with human scent significantly increased trap catches. Outdoor traps baited within industrial CO 2 or yeast-produced CO 2 + human odour reduced mosquitoes’ entry to the house with a human host under a bed net indoors. During the field trials, Anopheles gambiae s.s. was not caught. However, similar numbers of Anopheles arabiensis was caught in traps baited with yeast-produced CO 2 as traps baited with industrial CO 2 (Verhulst 28). Trap catches were increased by the addition of human scent.

In a Conclusion, CO 2 produced by Yeast can adequately replace CO 2 produced industrially for sampling of A Gambiae s.s. This will significantly allow sustainably and reduce costs of devices in a mass-application that are odour-baited for mosquito sampling in most of remote areas.Works CitedVerhulst, Niels O., et al.
