Mango Pest Alert
From G. Rapp
An excerpt from NAQS newslettter No. 12, Dec. 2000): The red-banded mango caterpillar (Deanolis sublimalis, synonyms are Deanolis albizonalis, Noorda albizonalis, Autocharis albizonalis) is present in Papua New Guinea and has been found on Gabba Island. It's the sixth detection in the Torres Strait between PNG and Australia since 1997. The caterpillar eats mango flesh and seeds. Symptoms of attack: Holes and sap flows on mango skins, caterpillar itself when the fruit is opened. Ecoport records this pest only from PNG. The AQIS website http://www.aqis.gov.au/docs/schools/rl/8120.htm records the pest also from Indonesia (Java), Philippines, Thailand, India and shows pictures of the pest and damaged mangos. As the name suggests, it has clear red and white bands around the body.

Notes on distribution
D. albizonalis is restricted to Asia. It has also been observed in the Andaman and Nicobar Island (M. Cook, International Institute of Entomology, London, UK, personal communication, 1996). The distribution map also contains records based on specimens of D. albizonalis from the collection in the Natural History Museum (London, UK), noted in the list of countries as "NHM Collection".

BIOLOGY AND ECOLOGY
D. albizonalis larvae bore into both young and more mature fruits producing a small dot at the point of entry, encircled by a dark brown ring. Larvae begin by feeding on the fruit pulp in which they form a network of tunnels, and later instar larvae feed on the seed. Up to eleven larvae have been found in a single fruit. Larvae take about 2 weeks to develop fully and mature larvae pupate inside the fruit or in the ground.
D. albizonalis has been described as a major pest in Orissa, India (Butani, 1979) and is said to have caused considerable damage in Andhra Pradesh, India in recent years (Zaheruddeen and Sujatha, 1993).
D. albizonalis is subject to quarantine in Australia.
Typical symptoms are the appearance of a small hole at the distal end of the fruit. This is encircled by a dark ring.
Descriptors: Fruits/pods: internal feeding; internal feeding.
D. albizonalis is a medium-sized moth (wingspan about 20 mm). The antennae are simple and the interantennal fillet is pale green with brushes of longer, reddish-brown scales on each side. The tongue is scaled and coloured white. Labial palpi have the second segment enlarged and are reddish-brown on the external surfaces, the maxillary palpi are small. The forewings have a white ground colour interspersed with darker scales. The darker scales are concentrated into a narrow dark-brown band along the termen, that is widest at the apex and tornus. There is also a faint and incomplete dark brown medial line. The ground colour of the hindwings is white, and there is a narrow, dark brown band along the apical half of the termen and a broad, pale-brown longitudinal band across the centre of the wings. The thorax is reddish brown with a pale green band along each side.
Larvae are red in colour with white intersegmental streaks and are about 25 mm long when fully grown. Description of pupae is not available.
SIMILARITIES TO OTHER SPECIES
The wing markings of the adult D. albizonalis moths are quite distinctive (see morphology below) and unlikely to be confused with any other mango-feeding lepidoptera.
DETECTION AND INSPECTION METHODS
Inspect fruits and look for entry points of D. albizonalis larvae, encircled by a dark brown ring and often with caterpillar frass.
No successful control methods have been recorded for this species.
