Abstract

We had previously reported in one of our studies that the irradiated males of Hyalomma anatolicum anatolicum were not able to compete with the normal males while mating with the females. In this study, it is aimed to determine the limitations of the competitiveness of irradiated males of H. marginatum in copulation in accordance with their numerical superiority over the nonirradiated males. We also intend to assign the applicable propotions and furthermore we would like to identify the main principles and conditions of possible field examinations. In this study, the male ticks were subjected to gamma radiation with a dose of 10 Gy emitted by a gamma-ray source of Caesium 137. Biological parameters such as feeding periods, weight, number of eggs and larvae hatching from the eggs of female 34 ticks that were placed in rabbit ears together with different numbers of irradiated, nonirradiated or a combination of both irradiated and nonirradiated male ticks were recorded. Reasonable numbers of ticks were employed in order to reach statistically reliable results. In conclusion, statistical analyses showed that the irradiated males of H. marginatum could not compete with the nonirradiated males in the case where these two groups had equal numbers of males. However, data analyzed from the study also deduced that the average number of eggs and larvae of females showed a reduction in trials for cases in which there were more irradiated males and this incident was found to be statistically significant. Finally, we came to the conclusion that our presented results have to be one of the key parameters which must be considered for field applications.

Özet

Daha önce yapmış olduğumuz bir çalışmada, irradie Hyalomma anatolicum anatolicum erkeklerinin, aynı sayıdaki irradie edilmemiş erkeklerle, dişi keneleri dölleme faaliyetinde rekabet edemedikleri görülmüştür. Bu çalışmada ise, irradie H. marginatum erkeklerinin döllemede rekabet gücü sınırlarının sayısal üstünlüklerine göre saptanması ve sahada yararlanılabilecek olası uygulama oranlarının ve esaslarının belirlenmesi amaçlanmıştır. Bu çalışmada, erkek keneler caesium137 kaynaklı Gamma radyasyon ile 10 Gy’lik dozda ışınlanmıştır. İstatistiksel farklılıkları ortaya koyabilecek sayısal oranlarda ışınlanmış ve ışınlanmamış erkekler ile aynı tavşan kulağına konan 34 dişinin ağırlıkları, dişilerin doyma süreleri, yumurta sayısı ve yumurtadan çıkan larva sayısı gibi biyolojik parametreler kaydedilmiştir. Sonuç olarak, gerçekleştirilen istatistiksel analizler, irradie H. marginatum erkeklerinin de sayısal eşitlik söz konusu olduğu taktir de ışınlanmamış erkeklerle belli bir rekabet gücüne sahip olmadıklarını göstermiştir. Ancak, eşitliğin erkekler lehine bozulduğu gruplarda yumurtasından larva çıkan dişi sayısı ile yumurta ve larva sayılarının azaldığı görülmüş, bu durumun istatistiksel olarak da önemli olduğu tespit edilmiştir. Elde edilen bu verilerin de olası saha denemelerinde göz önünde bulundurulması gereken parametrelerden biri olduğu sonucuna varılmıştır.
