| enumerative and binomial sampling plans for armored scale (homoptera: diaspididae) on kiwifruit leaves. | the spatial dispersion of armored scale insects; greedy scale, hemiberlesia rapax (comstock); and latania scale, hemiberlesia lataniae (signoret), was investigated on kiwifruit, actinidia deliciosa (a. chevalier) c. f. liang et a. r. ferguson, leaves in new zealand. a universal description for dispersion was determined using taylor's power law, which encompassed a wide range of different orchards, blocks, block sizes, sampling times, scale control practices, regions and seasons. scale density si ... | 2000 | 11142309 |
| dna diagnostics of three armored scale species on kiwifruit in new zealand. | three species of armored scale (hemiptera: diaspididae) are found on kiwifruit (actinidia spp.) in new zealand orchards: latania scale, hemiberlesia lataniae (signoret); greedy scale, hemiberlesia rapax (comstock); and oleander scale, aspidiotus nerii (bouché). each of them is a quarantine pest in some of the markets to which new zealand kiwifruit are exported. adult females of the three species can be distinguished morphologically; however, the task is laborious when large numbers must be ident ... | 2008 | 19133478 |
| rapid molecular identification of armored scale insects (hemiptera: diaspididae) on mexican 'hass' avocado. | 'hass' avocado, persea americana mill., fruit imported into california from mexico are infested with high levels of armored scale insects (hemiptera: diaspididae), constituting several species. the paucity and delicate nature of morphological characters traditionally used to diagnose armored scales often require careful preparation of slide-mounted specimens and expert knowledge of the group, for their accurate identification. here, we present a simple, quick, and accurate means to identify armo ... | 2009 | 19886461 |
| genetic diversity of armored scales (hemiptera: diaspididae) and soft scales (hemiptera: coccidae) in chile. | scale insects (sternorrhyncha: coccoidea) are one of the most invasive and agriculturally damaging insect groups. their management and the development of new control methods are currently jeopardized by the scarcity of identification data, in particular in regions where no large survey coupling morphological and dna analyses have been performed. in this study, we sampled 116 populations of armored scales (hemiptera: diaspididae) and 112 populations of soft scales (hemiptera: coccidae) in chile, ... | 2017 | 28515435 |
