Abstract

Arthropod pests of Annona cherimola in Japan were surveyed to find out if there are any economically important pests, and to examine if host shift or host range expansion of specialist herbivores from native plants to cherimoya has occurred over 14 y of cultivation in Japan. 21 insect and mite species were found by field observations and literature examination. The number of individuals for species found in the field survey was generally low, and thus none of them was considered economically important. All 21 species were polyphagous; the least number of recorded hoşt families was six. The proportion of polyphagous species was significantly higher than the mean proportion on other crops. The failure to detect host shift or host range expansion of stenophagous species to cherimoya may be due to the lack of indigenous annonaceous plants on the Japanese main islands, as well as the short time from the first introduction of cherimoya to Japan.
