Özet
Bu tez projesinde Efe ve Çanakkale yerli arısına sentetik bir neonikotinoid insektisit olan imidacloprid ve bitkisel kökenli neem ekstraktı (azadirachtin) ile bir flavonoid olan kuersetinin verilerek sağkalıma ne denli etkisi olduğu araştırılmıştır. Çalışma 30±2 C ve %30-50 nemde laboratuvar ortamında art arda 2 deneme olacak şekilde yürütülmüştür. Arılar 0-70 saat aralığında kuersetin ile beslenen ve beslenmeyenler olarak iki gruba ayrılmıştır. 72-96 saatler arasında iki grubun şerbetlerine imidacloprid ve azadirachtinin tavsiye edilen dozu eklenmiş; 96-120 saat aralığında yalnızca şerbet verilmiştir. 0-70 saat aralığında, kuersetin uygulanan ve uygulanmayan grupların şerbet tüketimleri Efe arısında 345,9 µL/arı, 338,6 µL/arı, Çanakkale ekotipinde 427,3 µL/arı, 427,9 µL/arı olmuştur. Pestisit uygulanan arıların şerbet tüketiminden kaçındıkları gözlenmiştir (P<0,0001). 72-120 saat aralığında genotipler arasında şerbet tüketimi farklılığı oluşmamıştır (P=0,9253). Arı başına iki saatlik su tüketimi ortalamalarında pestisit gruplarının, birinci denemede Efe arısı ayrı tutulursa, özellikle Çanakkale genotipinde belirgin olmak üzere kontrol grubundan daha yüksek olduğu gözlenmiştir (P<0,05). Pestisit uygulaması öncesi kuersetin ile beslenenlerin beslenmeyenlere göre sağkalım olasılıklarının %25 yükseldiği gözlenmiştir (P=0,0856). Çanakkale genotipine göre Efe genotipinin sağkalım olasılığının %37 daha düşük olduğu gözlenmiştir (P=0,0006). İmidaclopridin bu çalışma koşullarında oral yolla alımı sağkalım olasılığını %88 düşürmektedir. Azadirachtinin sağkalım olasılığına bir etkisi olmamıştır.
In this project, the effect of administration of imidacloprid, a synthetic neonicotinoid insecticide, and vegetable neem extract (azadirachtin) and quercetin, a flavonoid, on the survival of Efe and native Çanakkale bees was investigated. The study was carried out in a laboratory environment at 30±2 C and 30-50% humidity in two consecutive trials. Bees were divided into two groups: those fed with quercetin and those not fed between 0-70 hours. The recommended dose of imidacloprid and azadirachtin was added to the sugar syrups of both groups between 72-96 hours; only sugar syrup was given between 96-120 hours. Between 0-70 hours, syrup consumption of the groups with and without quercetin was 345.9 µL/bee, 338.6 µL/bee in Efe genotype, and 427.3 µL/bee and 427.9 µL/bee in Çanakkale ecotype. It was observed that bees treated with pesticides avoided consuming syrup (P<0.0001). There was no difference in syrup consumption between genotypes between 72-120 hours (P = 0.9253). The study found that the average water consumption per bee during a two-hour period was greater in the pesticide groups compared to the control group, particularly in the Çanakkale genotype (P<0.05). It was observed that the survival probability of those fed quercetin before pesticide application increased by 25% compared to those not fed (P = 0.0856). It was observed that the survival probability of the Efe genotype was 37% lower than the Çanakkale genotype (P = 0.0006). In this study, consumption of imidacloprid resulted in an 88%. Decrease in survival probability. Azadirachtin did not significantly impact the probability of survival
