In India, due to diverse ecological conditions, variety of fruit crops ranging from temperate to tropical, are grown. In mango and banana production, India is at top of the world. Now the trend of cultivation is shifting from traditional cereal crops towards horticultural crops, as they are nutritionally sound and give better returns. Beverage and plantation crops are important from export point of view. Pests at various stages of fruit crop growth, accounts for around 20 per cent loss to the growers and ultimately to the fruit industry. Hence, checking these losses is one of the important components of fruit cultivation. Even in the store, insect pests cause a substantial damage. For devising any management strategy, a knowledge on the identification, nature of damage, symptoms and life history is mandatory.

 
1 Introduction

Insects are prevalent on this globe due to their varied adaptations and hence constitute the largest component of the animal kingdom. Only around 5 per cent of the total insect species, act as pests, rest either are beneficial like honey bees, lac insect, silk worms etc. or are harmless. Insect pests can be of medical, veterinary, house hold and agricultural importance, as these creatures harm our health, animals’ health, our belongings and also the agricultural health. Though all these components are equally important but, in this book, the last one i.e. agricultural health, have been taken into consideration. Insect pests cause around 20 per cent loss to our crops by directly or indirectly affecting the crops both quantitatively and qualitatively. The insects have different types of mouth parts which are used for sucking, biting and chewing, sponging and lapping, siphoning etc. for food required for their survival and the insects with sucking and biting, and chewing types of mouth parts cause much of the damage. The mites (Phylum Arthropoda) though do not belong to class Insecta but in some instances also are of economic importance as they cause economic damage to agricultural crops and produce.

2 Pome Fruits

Various insect and mite pests infest fruit and plantation crops in different stages of crop growth directly or indirectly causing significant losses, hence need their management. The major pests of different fruit and plantation crops, their identification characters, life history, nature of damage and symptoms alongwith its management practices are described crop wise: Temperate fruits Pome fruits and stone and nut fruits are mainly cultivated in the temperate regions, which usually requires chilling requirements.
