“…The results of the present study showed that kefir, yogurt, and milk reduced the number of adults in Drosophila , thereby impeding development. The observation of a decrease in the number of adults in Drosophila is usually a result of the application of toxic substances ( Karataş and Bahçeci 2009a , Karataş et al 2011a , Karataş et al 2011b , Keser and Karataş 2012 ). Hence, it was unexpected that foods that are nutritious and beneficial for humans had such negative effects on Drosophila that they could be considered toxic.…”

“…This shows that males are more sensitive to kefir and females are more sensitive to milk and yogurt. Indeed, there are a number of studies showing that different substances have different effects on Drosophila in females and males, affecting female or male development in different ways ( Alentorn 1987 , Davey et al 1989 , Karataş and Bahçeci 2009a , Karataş et al 2011ab , Keser and Karataş 2012 ). It has been stated that protein and carbohydrates in Drosophila have different effects on the reproductive characteristics of the sexes and that this is due to the difference between the sexes in terms of reproductive strategies.…”

Due to the increased interest shown in kefir, the present study examined its effects on some developmental characteristics in Drosophila. To compare the results related to kefir, another fermented product, i.e., yogurt, and the raw material of kefir, i.e., milk, were included in the experiment. All three foods were fed to Drosophila by addition to the medium. The results showed that the three foods delayed development in generations F1 and F2. In both generations, the number of adults was lower than that of the control group, but the comparison of the foods among themselves showed no significant difference. Moreover, the negative effect continued in generation F2. Phenotypically abnormal individuals were observed in the experiments, but there was no significant difference. Furthermore, the sex ratio changed in all the groups, including the control group. In the experimental group fed kefir, the sex ratio changed in favor of females, whereas in the other groups, it changed in favor of males. Whether the milk and milk products were fermented did not change the effect on Drosophila, but unexpectedly it delayed development, reduced the number of adults, and changed the sex ratio. It can be concluded that the three foods delayed development and altered the sex ratio in Drosophila.

This study examined the effect of kefir, yogurt, and milk on egg production and development in Drosophila melanogaster Meigen. Kefir, yogurt, and milk were added to the Drosophila culture medium. First they were fed to mature individuals and then these females laid eggs on medium containing kefir, yogurt, and milk. Later the development of eggs and larvae was examined. The experiments were conducted on two generations, the F1 generation reared with additives in the media and F2 without the additives. The effects of these substances on the basic stages of development were also examined. In the experimental groups, the numbers of eggs and larvae decreased considerably in both the F1 and F2 generations. The comparison between the experimental groups themselves also showed a difference. In both generations, development of eggs into third instar larvae was reduced and metamorphosis was delayed. In addition, morphological abnormalities were observed in the larvae. Overall the results showed that kefir, yogurt, and milk affected egg and larva development negatively and this negative effect continued in the F2 generation. The continuation of this negative effect in the F2 generation, which was not exposed to various milk additives, is an interesting finding. These results indicate that the nutrients from the milk and the milk products used were neither utilized by nor beneficial for this insect.

In this study, the effects of a porphyrazine derivative, [octakis (2-trimethylammoniumethyl thio) porphyrazinatocobalt] octaiodide (CoPzq), were explored on the developmental characteristics, sex ratio and egg fertility of Drosophila melanogaster. CoPzq was preferred in the study due to its probability to be used as a chemotherapeutic agent in medicine. As a result of the application of CoPzq, a phenotypic abnormality was revealed within the individuals of F1 and F2 generation of Drosophila. Although individuals of F2 generation did not directly come into contact with the chemical, the rate of abnormality is high. An increase was observed within both generations in terms of the egg fertility. Besides, a deviation emerged in the sex-ratio in some concentrations.
