Materials and Methods 2. Firstly we thank God Almighty whose blessing were always with us and helped us to complete this research work successfully. Descriptive statistics using SPSS The data were checked for normal distribution using Kologovic-Smiroff KS test. Non-destructive methods were followed using sample collection process. The lowest HW among workers was 1.
A PCA was performed using a correlation matrix was performed on selected 16 characters which seems to be significant in the study. The first author would wish to thank beloved Manager Rev. 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. The samples were labelled according to the location and stored in airtight boxes until morphometric analysis were conducted. ANNOVA of morphometric characters among workers and drones across various districts in Kerala showed difference in statistical significance among the two castes. 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. Trigona iridipennis Smith are kept in India for centuries for the high medicinal value of honey as well as propolis and bee wax Rasmussen, ; Cortopassi-Laurino et al.

Also a total 61 different pollen morphs were observed in study, out of which 9 were identified as Bougainvillea peruviana, Brassica spp. Iridipennis honeythe T.
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. Biology – Zoology Novel and innovative techniques in Me Studies on characterization and behavior of the stingless bee Tetragonula iridipennis Smith with biochemical properties of its honey. Chapter 2 is a comparative study of aggression in nest defence among stingless bee species, and describes a new form of nest defence, suicidal biting, which is most prevalent in the genus Trigona.

However, there is not much significant differences among drones across various districts. 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. Stinglesd – Micro- and Molecular Biology Isolation and molecular characterizat Morphometric characterization of stingless bees Trigona iridipennis Smith in Kerala: The cropping pattern of the collected sites vary with a wide variety plantation bers were natural rubber dominates all the other crops Figure 2.
Site description of the selected farms W1-W21 across Kerala, India for collecting worker bees during Distribution of factor scores among stingless bee drones across various locations in Kerala. Based on stinglrss back ground, our objectives of this study were to 1 to characterize the morhometric aspects of drones and worker in Trigona iridipennis Smith 2 to identify the various similarities and differences existed among based on factor and principal component analysis.
Chapter 4 studies nest defence in the hovering guards of Tetragonisca angustula, and demonstrates that through coordinated vigilance, a group level behaviour rarely observed in animals, the ability of the group to detect predators is enhanced.
Morphometric characters considered for the analysis of worker and drone bees of stingless bees in Kerala: Our studies revealed beex most of the worker morhopometric characters were positively correlated across all the districts in Kerala.
