STINGLESS BEES THESIS

The thermoregulation studies during April-May revealed that T. Little is known about the variations exist among them. Agrarian Studies Morphological diversity, nutritional Non-destructive methods were followed using sample collection process. Majority of cups were removed by bees, however the bees accepted 2 installed cups of 5mm dia propolis cup sealed on 5th day after installation and 8mm dia propolis cups sealed on 13th day after installation. The lowest HW among workers was 1.

Based on our studies, even though we detected significant differences among worker morhphotmetry we could not to find distinguishing and remarkable differences among collected samples. ANNOVA of morphometric characters among workers and drones across various districts in Kerala showed difference in statistical significance among the two castes. Introduction Despite of role in pollination and ecosystem services, honey bee population is drastically decreasing due to destruction of natural habitat, intensive agriculture, diseases and climate change et al. Kerala state covers an area of 38, km2 with a population density of per km2 and spread across 14 districts Figure 2. K Head of the Department, Biotechnology for the valuable suggestions, support and encouragements.

The validity PCA of 21 morphometric characters was justified as indicated by the Kaiser-Meyer-Olkin measure of sampling adequacy of 0.

Site description of the selected farms D1-D9 across Kerala, India for collecting drone bees during The major species of stingless bees in Kerala is Trigona iridipennis Smith which are easy to domesticate due to low temperament and easy adaption to various habitats. Kerala state covers an area of 38, km2 with a population density of per km2 and spread across 14 districts Figure 2.

Even though numeric significance were shown, most of the morpometric characteristics of drones except AL and MdL were statistically non significant. Studies on characterization and behavior of the stingless bee Tetragonula iridipennis Smith with biochemical properties of its honey.

Pantnagar, Uttarakhand, India, on the characterization and behaviour of stingless bee, Tetragonula iridipennis Smith along with biochemical properties of its honey. We lovingly and gratefully indebted to our thhesis, parents, siblings and friends who were there always for helping us in this project.

The studies showed good possibilities of using artificial storage cups in stingless bees colonies which in turn will improve the harvesting process of its honey. Our studies revealed that most of the worker morhopometric characters were positively correlated across all the districts in Kerala. The investigations were carried out during at G. Distribution of factor scores among stingless bee drones across various locations in Kerala. Person correlation analysis showed considerable correlation among various morphometric characters in worker and drone bees across Kerala.
