Introduction<br />
This illustrated Field Guide gives an introduction to the identification <strong>of</strong><br />
some common pests, beneficials, diseases <strong>and</strong> disorders <strong>of</strong> mangoes<br />
in northern Australia (<strong>Northern</strong> Territory, northern Queensl<strong>and</strong> <strong>and</strong><br />
northern Western Australia). It also includes a description <strong>of</strong> several<br />
beneficial insects <strong>and</strong> spiders, as well as some nutritional <strong>and</strong><br />
physiological conditions that may be confused with pest or disease<br />
symptoms.<br />
The information in the Field Guide is the best available at the time<br />
<strong>of</strong> publication <strong>and</strong> includes some life cycle development times which<br />
have been approximated for NT conditions (these will vary according<br />
to climatic conditions, human influences <strong>and</strong> environmental factors).<br />
Many other insects or mites may be found on mango trees <strong>and</strong>/<br />
or on mango fruit, including some that are <strong>of</strong> minor (or infrequent)<br />
economic importance as well as non-economic species. Growers are<br />
encouraged to be on the lookout for any new or unusual occurrences<br />
<strong>and</strong> to discuss these <strong>and</strong> any other concerns with departmental staff.<br />
How to Use This Field Guide<br />
This publication is divided into four main sections: insect pests, natural<br />
enemies, diseases <strong>and</strong> disorders. A monitoring bar grid has been<br />
provided to show which months the orchard should be monitored<br />
for a particular pest, disease or disorder. Some insects or mites may<br />
occur during the wet season months <strong>of</strong> December to February but<br />
monitoring is not usually essential during that period as trees are not<br />
flushing or producing flowers.<br />
The crucial time for insect monitoring is during the period <strong>of</strong> flushing,<br />
flowering <strong>and</strong> fruit production, which includes the period from March<br />
to November.<br />
A glossary at the back <strong>of</strong> this book has been provided for definitions<br />
<strong>of</strong> scientific terms.<br />
