Book Description
A much-needed new study on plant galls growths on plants formed of plant tissue that are caused by other organisms. Most naturalists have come across oak apples, robin s pincushions, marble galls and witches brooms, a few of the more familiar examples of the strange growths that are plant galls. They are beautiful, often bizarre and colourful, and amazingly diverse in structure and in the organisms which cause them. They have been known since ancient times and have attracted superstitions and folk customs. Both the ancient Greeks and the Chinese used them in herbal medicine, and until well into the nineteenth century, they had a variety of commercial uses: important for dyeing cloth, tanning leather and for making ink. Knowledge of gall types increased during the late nineteenth century and throughout the twentieth century as more species were described and their structure became more clearly understood, and yet even today, little is known about the mechanisms that cause gall formation as well as the life cycles of the organisms that initiate gall growth. Since most galls do not cause any economic damage to crop plants, research funding has traditionally been sparse in this area. However, the insect cycles and gall structures are amazing examples of the complexity of nature. Margaret Redfern explores these fascinating complexities in this latest New Naturalist volume, providing much-needed insight into the variety of galls of different types caused by a wide range of organisms including fungi, insects and mites. She discusses the ecology of galls more generally and focuses on communities of organisms within galls, the evolution and distribution of galls, as well as human and historical perspectives."

Book Description
What are plant galls and how are they caused? This book introduces both the Australian native insects that induce galls on plants and the plant species that host them. It explores the ways the insects have adapted to living part of their lives in the confined spaces of galls, and describes the strategies employed by different insect groups to find a suitable site to induce a gall, obtain food, mate and escape the gall. Life in a Gall also looks at the predators, parasitoids, inquilines, kleptoparasites and micro-organisms that prey on gall-inducing insects and the ways the insects defend themselves from these enemies. It covers the problems gall-inducing insects can cause agriculture, forestry and horticulture and gives examples of several pest species. On the positive side, the book describes the essential services gall-inducing insects provide by pollinating figs, controlling invasive weeds and contributing to indigenous food. The final chapter provides tips for people who want to collect and study galls, and shows that answering many of the questions still surrounding gall-inducing insects is not restricted to professional scientists but can be achieved by diligent amateurs too.

Book Description
Galls are growing plant parts and require nutrients just like other plant parts. It's possible that galls steal vital plant food and adversely affects plant growth. This is most likely a problem when galls are numerous on very young plants. Injury may also occur if galls are numerous on branches or if abundant for several consecutive years. In most cases, however, galls are not abundant enough to harm the plant. So it can be concluding that, management of gall-forming agents like mites, insects, bacteria, fungi etc. are necessary & in management include biological control, chemical control, prevention etc. But, Gall is rich source of tannins,
