Summary of Invasiveness

Top of page A. fuscocupreanus has spread to North America from Asia, presumably carried as egg masses on hosts. It has established and spread in the north-east and north-west of the USA. On the basis of the latitudes of its distribution in eastern Asia, Maier (2003) suggests that A. fuscocupreanus could extend its range in North America from Newfoundland in the north to Georgia in the south.

Notes on Taxonomy and Nomenclature

Top of page The larvae feed on a range of host plants and the adults can appear quite variable, which perhaps explains why this organism was described [named] twice by Matsumura.


Top of page Eggs

The eggs are less than 1 mm long and oval. They are laid together in a single, circular egg mass, up to 7 mm in diameter, on tree trunks or larger branches. The egg mass is black.


The early-instar larvae are black and grey. The later-instar larvae are greyish-green with an orange or brownish head capsule and a black thoracic shield behind the head. When fully grown they are 19-22 mm long.


The pupae are 9-11 mm long and dark brown. They are formed in folded leaves or under the loose bark of tree trunks or leaf litter.


The wingspan of the males and females is 16-22 mm and 20-24 mm, respectively. The forewings are darker brown than the hindwings. The wings have dark-brown markings with orange or reddish-brown tinges. The hindwings are greyish-brown. Colour plates showing variation in the adults are provided in Mutuura et al. (1969) and Inoue et al. (1982).


Top of page A. fuscocupreanus is native to Japan where it can be found in all apple-growing regions and where it is an important pest (Tsugawa, 1971). In 1995, this pest was detected in five counties of western Washington State, USA (NAPPO, 1996; LaGasa, 1997). It had been established in Connecticut, USA since at least 1982, although it was not positively identified until 1995 (Maier and Mastro, 1998). It has become firmly established in the north-eastern states of the USA. For example, it was the fourth most abundant tortricid of 10 species found in total, in unsprayed apple orchards in a Connecticut county in 1997 (Maier and Mastro, 1998).

Risk of Introduction

Top of page A. fucocupreanus is not on any Regional Plant Protection Organisation's lists of quarantine pests. However, its spread from Japan to the USA, and its subsequent further spread within the USA does suggest that it is an invasive species. On the basis of its pest status in Japan, it could be a risk to fruit and nursery industries in temperate regions in North America (Maier, 2003). In the USA, normal orchard pest control programmes could be expected to effectively manage the organism (NAPPO, 1996). Further spread may occur via the transport of nursery plants infested with the inconspicuous black egg masses.

Hosts/Species Affected

Top of page Although this species has a broad host range, feeding on 87 plants in 15 families, it is most abundant on Malus, Pyrus and Morus, and is only occasionally found on other genera. In the USA, the majority of hosts are Rosaceae (Maier, 2003).

Growth Stages

Top of page Flowering stage, Fruiting stage


Top of page There are two types of symptoms: feeding damage to the leaves, blossoms and developing fruit caused by the larvae; and the more characteristic folded or rolled damage to leaves and flower parts, caused when the larvae make shelters using silk.

Biology and Ecology

Top of page A. fuscocupreanus is univoltine. Usually each female lays one egg mass in a protected area on a trunk or branch of a host from mid June to early July. The eggs overwinter and remain in diapause until the spring of the following year. The hatching date for egg masses varies according to the differences in position of egg deposition on trunks and branches. The date of hatching is heavily influenced by solar radiation and micro-habitat temperatures, with eggs in masses on south-facing trunks hatching first (Oku and Ohira, 1987). The eggs hatch from late April to mid-May, with 50% hatching coinciding with the flowering of apple blossoms. The young larvae feed on developing leaves. The older larvae also eat flowers and may graze fruit (Oku, 1967). The larvae feed until mid-May or mid-June. There are four larval instars. Pupation occurs towards the bottom of the host plants or in the soil close to hosts. The adults appear from mid-June to early July (Sekita and Yamada, 1990). The threshold temperature for the development of the egg is 7.3°C, 8.1°C for the larva, and 10.7°C for the pupa (Oku, 1970). Laboratory experiments carried out at 15, 19 and 23°C showed that longevity, duration of the pre-oviposition and oviposition periods, and rate of mating decreased with temperatures above 15°C (Ohira, 1990). Kuzuhiro and Shigemi (1997) used accumulated temperature to forecast the occurrence of A. fuscocupreanus in Japan. Their forecasts were reported to be accurate within 5 days.

Notes on Natural Enemies

Top of page In unsprayed orchards, Trichogramma species can parasitize 60% of eggs (Ohira and Oku, 1992). The listed natural enemies are not host specific and have a wide range in Eurasia (D Greathead, [address available from CABI], personal communication, 2005).

Means of Movement and Dispersal

Top of page Movement in Trade

Egg masses of A. fuscocupreanus could be carried on the branches and trunks of dormant hosts. Hosts such as Malus, Prunus, Pyrus and Rosa are traded internationally. The spread of this pest from Japan to the USA suggests that pathways for the intercontinental movement of A. fuscocupreanus exist. The transport of soft-bodied larvae with host fruit is unlikely. In the USA, A. fucsocupreanus is not a pest of actual fruit, and commercial fruit movement does not present a risk of transporting the pest (NAPPO, 1996).

Top of page A. fuscocupreanus is a pest of orchard crops. It has been considered a major apple pest in Japan for many years where it is one of the three most important leaf-roller pests (Tsugawa, 1971; Sekita et al., 1994). The larvae feed on the buds, flower clusters, petals, fruitlets and leaves of host plants. A colour plate showing damage to petals is provided in Sekita et al. (1994). When abundant, the larvae can defoliate fruit trees. The older larvae attack fruit when it is small, thus feeding damage to fruit can be serious. The fruit may not survive the attack, thus causing direct crop losses, or the fruit may be rejected on quality grounds because feeding damage can cause fruit to be severely misshapen and blemished and hence unmarketable (Sekita et al., 1994). As well as larval feeding damage, injury is caused by webbing leaves and occasionally flowers or fruitlets together when the larvae form shelters. The economic threshold for treatment in apple orchards is one egg mass per tree (Ohira and Oku, 1996). In Japan, A. fuscocupreanus is recorded as a pest of pears (Pyrus communis) (Yukinari, 1976), mulberry (Morus alba) (Yoshii and Yokoi, 1984) and blue honeysuckle (Lonicera caerulea) (Mizukoshi, 1988).

Detection and Inspection

Top of page In the winter, the trunks and larger branches of hosts can be visually examined for egg masses. In the spring and summer, the leaves and flowers on branches can be scanned for signs of feeding damage or folded and rolled leaves.

Similarities to Other Species/Conditions

Top of page Adult A. fuscocupreanus are very similar to the European leafroller or rose tortrix, Archips rosanus. The costal fold on the male forewing is broad and is approximately one-third the length of the costal margin. In contrast, A. rosanus has a narrow costal fold that extends approximately half the length of the costal margin of the forewing. Examination of the male genitalia can also be used to separate species. The larvae of A. fuscocupreanus are similar to larvae of Choristoneura rosaceana (oblique-banded leafroller).

Prevention and Control

Top of page In Japan, conventional organophosphate compounds have provided control when applied before apple blossoms open (Sekita et al., 1994). However, A. fuscocupreanus has developed some resistance to insecticides in Japan (Ohira and Oku, 1992). Mating disruption can be an effective management option (Toshiaki et al., 2002). The pheromone (Z)-11-tetradecenyl acetate (Hamakikon-R) disrupts mating thus causing reduced and delayed oviposition (Ohira and Oku, 1992; Oku, 1993). When mating disruption was applied against A. fuscocupreanus and insecticides were excluded, egg mortality due to parasitism increased. The population of A. fuscocupreanus was kept below damaging levels, without the need for additional control, for the succeeding three generations (Ohira and Oku, 1996).
