Abstract
A standard, monofunctional alkylating agent, Methyl methanesulfonate, was tested for its effects on courtship behavioral elements in Drosophila melanogaster. Different concentrations ranging from 0.1 to 3 mM were analyzed using the larval feeding technique. When the different combinations of crosses were performed to analyze the effects, the results have revealed that male courtship elements such as orientation, tapping, wing vibration and licking were significantly increased compared to controls. Similar data were observed in case of female behavior. Nonetheless, the courtship behavior interms of fitness such as courtship latency and copulation latency were significantly high and copulation duration was significantly reduced, thus emphasizing the effect on fitness and inturn viability. On par with earlier data on toxicity, the present results also demonstrate the drastic effects of Methyl Methanesulfonate (MMS) on the courtship behavior of D. melanogaster. Thus, it is opined that courtship elements as a parameter can be utilized to understand toxicity and also it can be analyzed within a short period of time.
