Several Jatropha pests, Cambodia Minimize

April 2010. Several insects collected from Jatropha were sent for identification from Cambodia.

1) The bug (top). It is Spilostethus pandurus Scopoli (Hemiptera: Lygaeidae). It is a known pest of cotton in Asia and is always confused with the dusky cotton bug, Dysdercus cingulatus F. (Hemiptera: Pyrrhocoridae). In the Middle East it attacks pistachio and is called pistachio red bug.

There was also a suggestion that it was the Small milkweed bug Lygaeus kalmii (Lygaeidae). See:

2) The weevil (middle, left): It is Hypomeces squamosus (F.) (Coleoptera: Curculionidae). It is a common polyphagous leaf-eating weevil known as the green weevil or the gold-dust weevil.

3) The Katydid (middle, right). May be the longhorn grasshopper, false katydid. It was said to be feeding on the caterpillars of Pempelia morosalis (lower right).
