| Abstract:
The insects and mites on kiwifruit leaves from several regions of Chile were assessed quantitatively or semi-quantitatively in 1992. The results revealed the same species of armored scales (Homoptera: Diaspididae) as are present in New Zealand, Hemiberlesia rapax, H. lataniae and Aspidiotus nerii, Scale densities on leaves in each country were comparable, in contrast to the different levels reported for fruit. In some Chilean orchards Saissetia oleae (Homoptera: Coccidae) was common on kiwifruit leaves. Leafroller caterpillars (Lepidoptera: Tortricidae) were less common in Chilean kiwifruit orchards than in New Zealand, where several endemic species form a major pest group. In Chile the endemic Brevipalpus chilensis (Acarina: Tenuipalpidae) was the most numerous mite encountered, reaching greater populations than the most common mites in New Zealand, the tydeid mites Orthotydeus californicus and O. caudatus (Acarina: Tydeidae). Three species of spider mite (Acarina: Tetranychidae) were found in Chile. Two of these, two-spotted mite Tetranychus urticae and six-spotted mite Eotetranychus sexmaculatus, also occur in New Zealand. Phytoseid predators were more common in Chile than New Zealand. | |
