Book Description
Stingless bees/Dammer bees are the smallest of the honey producing bees. Trigona and Melipona are the most important geera of stingless bees. Trigona is the largest and most widely distributed genus, which incluse 130 species under ten sub-genera. the present studies were taken with the following objectives 1) to study nesting charateristics, biology and seasonal variations, 2) to study foraging behaviour of Trigona iridipennis Smith in comparison with Apis cerena indica, 3) to identity the major food sources of T. iridipennis and A. cerena, 4) to study pollination potentiality of stinglees bee T. iridipennis on certain crops. The total period required from oviposition to adult emergence was 53.30 days comprising 5.75, 12.70, 35.30 days for egg, larvae and pupal stages, respectively. The length of this period was 2.53 times more than that of A. cerana. The marked adults of T. iridipennis had a life span ranging between 80-87 days. The time spent by different species of honeybees in collection of pollen was maximum at 0800 hrs and for nectar from pistillate and staminate flowers was at 1600 hrs. The flower drop in control plot (89.50 %) was found to be significantly higher over other treatments. Maximum fruit set, fruit weight and fruit volume was recorded in open pollinated plot than T. iridipennis caged and control plots. T. iridipennis contributed for 61.00 per cent fruit set while it was only 10.50 per cent in control plot. The germination percentage was found significantly higher in the seeds of open and T. iridipennis pollinated seeds compared to seeds from control plot.

Book Description
Scientific Study from the year 2016 in the subject Biology - Miscellaneous, , language: English, abstract: Stingless bees are highly social insects which populated the tropical earth 65 million years ago and have been around much longer than honey bees. They are limited to the tropics and subtropics, lack a venom apparatus and cannot sting. Impacts of anthropogenic influences on honey bees have already been reported. Recent studies also showed that the nesting behaviour of Trigona iridipennis Smith in its natural habitat also varies due to interaction, pheromones and environmental stimulus. Little is reported so far about the various natural and domesticated nesting of the Trigona iridipennis Smith in Kerala. Based on thise background, our objectives of this study were to 1) to characterize the Meliponiculture 2) to identify the various natural habitats and domestication materials for nest construction and different types of nests used across Kerala. Various beekeeping methods preferred by farmers across Kerala for the cultivation of Trigona iridipennis Smith. Each nest has its own advantage and disadvantage. During the survey, the most preferred ones were wooden box. Even then according to the easy availability and production cost different nests like earthen pot, bamboo nodes, coconut shell, PVC pipes etc were used. The most preferred natural nesting sites by Trigona iridipennis Smith were mud/stone walls in our study. Being a social insect, Trigona iridipennis Smith shows great diversity in nesting pattern in natural habitats as well as anthropogenic habitats. The shift towards anthropogenic habitats than natural ones may be due to destruction of natural habitats as well as the availability of manmade habitats.

Book Description
Stingless bees (Meliponini) are the largest and most diverse group of social bees, yet their largely tropical distribution means that they are less studied than their relatives, the bumble bees and honey bees. Stingless bees produce honey and collect pollen from tens of thousands of tropical plant species and, in the process, provide critical pollination services in the tropics. Like many other insects, they are struggling with new human-made challenges like habitat destruction, climate change and new diseases. This book provides an overview of stingless bee biology, with chapters on the evolutionary history, nesting biology, colony organisation and division of labour of stingless bees. In addition, it explores their defence strategies, foraging ecology, and varied communication methods. Accordingly, the book offers an accessible introduction and reference guide for students, researchers and laypeople interested in the biology of bees.

Book Description
Arthropods are invertebrates that constitute over 90% of the animal kingdom, and their bio-ecology is closely linked with global functioning and survival. Arthropods play an important role in maintaining the health of ecosystems, provide livelihoods and nutrition to human communities, and are important indicators of environmental change. Yet the population trends of several arthropods species show them to be in decline. Arthropods constitute a dominant group with 1.2 million species influencing earth’s biodiversity. Among arthropods, insects are predominant, with ca. 1 million species and having evolved some 350 million years ago. Arthropods are closely associated with living and non-living entities alike, making the ecosystem services they provide crucially important. In order to be effective, plans for the conservation of arthropods and ecosystems should include a mixture of strategies like protecting key habitats and genomic studies to formulate relevant policies for in situ and ex situ conservation. This two-volume book focuses on capturing the essentials of arthropod inventories, biology, and conservation. Further, it seeks to identify the mechanisms by which arthropod populations can be sustained in terrestrial and aquatic ecosystems, and by means of which certain problematic species be managed without producing harmful environmental side-effects. This edited compilation includes chapters contributed by over 80 biologists on a wide range of topics embracing the diversity, distribution, utility and conservation of arthropods and select groups of insect taxa. More importantly, it describes in detail the mechanisms of sustaining arthropod ecosystems, services and populations. It addresses the contribution of modern biological tools such as molecular and genetic techniques regulating gene expression, as well as conventional, indigenous practices in arthropod conservation. The contributors reiterate the importance of documenting and understanding the biology of arthropods from a holistic perspective before addressing conservation issues at large. This book offers a valuable resource for all zoologists, entomologists, ecologists, conservation biologists, policy makers, teachers and students interested in the conservation of biological resources.

Book Description
The stingless bees are one of the most diverse, attractive, fascinating, conspicuous and useful of all the insect groups of the tropical world. This is a formidable and contentious claim but I believe it can be backed up. They are fifty times more species rich than the honey bees, the other tribe of highly eusocial bees. They are ubiquitous in the tropics and thrive in tropical cities. In rural areas, they nest in a diversity of sites and are found on the flowers of a broad diversity of crop plants. Their role in natural systems is barely studied but they almost certainly deserve that hallowed title of keystone species. They are popular with the general public and are greatly appreciated in zoos and gardens. The chapters of this book provide abundant further evidence of the ecological and economic importance of stingless bees.
