Abstract

In contrast to honeybees, Bombus. terrestris workers are also capable of egg laying toward the end of the colony life even if in the presence of the queen. Males are produced from these unfertilized haploid eggs laid by both queens and workers. In a colony, males which produced from queen and reproductive worker eggs are not different morphologically. In mass rearing process under controlled conditions, all males which produced in colonies are collected and mated with young queens. This experiment was carried out to compare the development traits of colonies founded by queens mated with these two male groups. To produce two different male groups, old workers groups and virgin queens groups were formed and males were produced by these groups. Young B. terrestris queens produced by standard colonies were mated with males in two groups. After the hibernation period, queens were allowed to found colonies and some colony development characteristics were determined. Results showed that no significant differences in the all colony development characteristics except colony foundation ratio (P<0.05) were determined between colonies founded by queens mated with males produced by queens and reproductive workers.

Özet

Bal arılarının aksine Bombus terrestris kolonilerinde yaşam döngüsünün sonlarına doğru ana arı ile birlikte işçi arılar da yumurtlamakta ve hem kurucu ana arı hem de işçi arılar tarafından yumurtlanan bu haploid yumurtalardan erkek arılar üretilmektedir. Kolonilerde ana arı ve işçi arı yumurtalarından gelişen erkek arıların morfolojik olarak ayrılabilmesi söz konusu olmayıp, kitlesel yetiştiricilikte kolonilerde üretilen tüm erkek arılar çiftleştirme amacıyla kullanılmaktadır. Bu çalışma B. terrestris arısında hem ana arı hem de işçi arılar tarafından yumurtlanan haploid yumurtalardan üretilen erkek arılar ile çiftleşen ana arıların oluşturduğu kolonilerin gelişim özelliklerini karşılaştırmak amacı ile yürütülmüştür. Araştırmada yaşlı işçi arı grupları ve çiftleşmemiş ana arı grupları oluşturularak her iki grup için erkek arılar üretilmiş ve bu erkek arılar standart kolonilerde üretilen genç B. terrestris ana arıları ile çiftleştirilmiştir. Diyapoz dönemi sonunda bu ana arıların oluşturduğu kolonilerde bazı koloni gelişim özellikleri belirlenmiştir. Araştırma sonuçları ana arı ve işçi arılar tarafından yumurtlanan haploid yumurtalardan üretilen erkek arılar ile çiftleşen ana arıların koloni oluşturma performansları ve oluşturdukları koloniler arasında belirleyici gelişim özellikleri bakımından önemli bir farklılık olmadığını göstermiştir.
