Scientific name: Creatonotus (= Phalaena) gangis (= interruptus) Linnaeus
Common name: Hairy caterpillar, Tiger moth
The insect is not an important pest of rice. It is not commonly found in rice environment.
South and Southeast Asia
The larva defoliates the plant. Whole plant can be eaten leaving only the stem bases of the host plant.
Biology and Ecology
On rice plant, each female deposits 6 to 47 individual eggs in rows on the leaf. Egg incubation is 4-5 days. There are five larval instars observed in 20-23 days. Prior to pupation, a two-day prepupation period is observed. Pupation takes 8-9 days. The adult moths can live until 12 days. The total developmental period from egg to adult takes about 37 days.
In a greenhouse experiment in the Philippines, it feeds on grasses, sedges and broadleaves. The plant hosts are rice, Leptochloa chinensis (L.) Nees, maize, Echinochloa colona (L.) Link, E. glabrescens Munro ex Hook f., Eleusine indica (L.) Gaertn., Isachne globosa L., Paspalum scrobiculatum L., P. conjugatum Berg., Leersia hexandra Sw., Brachiaria mutica (Forsk..) Stapf., B. distachya (L.) Stapf., Chloris barbata Sw., Imperata cylindrica (L.) Beauv., Cyperus kyllingia Endl., C. brevifolius (Rottb.) Hassk., C. iria L., C. rotundus L., Fimbristylis miliacea (L.), and Commelina diffusa Burm. F., coffee, groundnut, and lucerne.
Detection and Inspection
The adult is easily recognized because of its color and marking. The larva is easily seen from the plant because of its long black hairs covering the body.
No control measures for the insect is available.
