Fauna Malesiana aims to diffuse knowledge of the zoodiversity of Southeast
Asia, and to make it accessible to both expert and layman. A core activity of
the Foundation is the production of Handbooks and Field and Study Guides. Field
and Study Guides are identification guides with various possible formats, ranging
from limited monograph-type guides to a little known group, intended to raise
general awareness, to books of a more practical nature, aiding professionals
in the applied sciences. The present guide is an example of the latter type.
Several studies dealing with various pest insects in the Indo-Malayan region have been published in the past, including Kalshovens monumental The Pests of Crops in Indonesia. The most important pests were either described in relation to a particular crop or to a specific geographical area. These publications were often expensive and difficult to obtain, which formed an obstacle for those who most needed them: people working in the agricultural sector in the region. Our principle goal with this field guide is to make the available knowledge about Indo-Malayan pest Orthoptera (including the lesser known species) accessible to the people who may benefit the most from this information.
Throughout the production of this Field Guide, our imaginary audience consisted of professionals, such as agriculturists, agricultural officers, economic entomologists, extension workers, rural development officers, but also students of agriculture, agronomy, general entomology, forestry, etc. We hope that this field guide will prove to be useful, both for people who know about agricultural problems and are interested in identifying the possible orthopteran culprits, as much as for people who know about orthopterans and are interested in the problems they may cause.
This guide aims to facilitate the identification of grasshoppers, locusts,
bushcrickets and crickets (Orthoptera) that are known or suspected to act as
pests in the Indo-Malayan region, and to summarize published information on
their distribution, biology, ecology, food plants and economic importance.
In principle, all species of Orthoptera are included that have been mentioned in the literature as pest species in the Indo-Malayan region (Malaysia, Singapore, Indonesia, the Philippines and Papua New Guinea). A few species, like Chrotogonus spp. and Tridactylus spp. on Brassica spp., the crickets Oecanthus spp. on tobacco, Gryllus bimaculatus on coffee and sugar cane in the Philippines and Erucius apicalis on cacao in Malaysia, have been mentioned in the literature without any further notice. Because of this lack of information they have been excluded here.
An illustrated key is provided for the identification of the species and species groups treated in this guide. As far as possible, the key uses characters that are discernable without a magnifying glass. Inevitably, in some cases characters had to be used that require the use of a hand-lens or stereo-microscope. For some species groups a key to the level of species is lacking since identification would require the examination of male and female genitalia. Readers interested in the identification of these species are referred to the specialized taxonomic literature.
In the systematic section, families are characterized morphologically, and general remarks on their distribution, species numbers worldwide, and biology are provided. Information for each species (or species group) includes, as far as known, notes on nomenclature, morphology, distribution, life cycle, ecology and behaviour, food plants and economic importance.
