Mutagenicity studies in Drosophila melanogaster with Lannate 20
Abstract:
Lannate 20 a carbamate pesticide was evaluated for its mutagenicity in Drosophila melanogaster by the sex-linked recessive lethals and chromosome II-III translocation tests by continuous larval feeding. The 3 sublethal doses of 0.2, 0.4 and 0.6 microliter of Lannate per 100 ml of the food medium induced a significant (P less than 0.01) increase in the number of sex-linked recessive lethals over the controls. However, no translocations were observed either in the treated or the control series.
Insights
The pesticide Lannate 20 significantly increased sex-linked recessive lethals in Drosophila melanogaster, indicating mutagenic potential. However, it did not cause chromosome translocations in this study.
Area of Science:
- Toxicology
- Genetics
- Pesticide Research
Background:
- Carbamate pesticides are widely used in agriculture.
- Assessing pesticide mutagenicity is crucial for environmental and health safety.
- Drosophila melanogaster is a model organism for genetic toxicity testing.
Purpose of the Study:
- To evaluate the mutagenicity of Lannate 20, a carbamate pesticide.
- To determine if Lannate 20 induces genetic mutations in Drosophila melanogaster.
Main Methods:
- Continuous larval feeding of Drosophila melanogaster with sublethal doses of Lannate 20.
- Sex-linked recessive lethal tests were performed.
- Chromosome II-III translocation tests were conducted.
Main Results:
- A significant increase (P < 0.01) in sex-linked recessive lethals was observed with Lannate 20 exposure.
- No chromosome translocations were detected in treated or control groups.
Conclusions:
- Lannate 20 exhibits mutagenic activity by inducing sex-linked recessive lethals in Drosophila.
- Lannate 20 did not demonstrate clastogenic effects (translocations) under the tested conditions.
