oa Journal of the Entomological Society of Southern Africa - Observations on the Behaviour of Crawlers of Lepidosaphes beckii Newm. (Hom.: Diaspidinae)

Citrus mussel scale, Lepidosaphes beckii Newm. (Diaspidinae), is common in citrus orchards in various parts of South Africa. It attacks all varieties of citrus, and in some places is now regarded as a major pest. During 1954 an opportunity was offered for studying this insect in orchards of the Eastern Cape Province, and in the course of this work the following observations on mussel scale crawlers were made. The distribution and spread of this scale is effected entirely by the crawlers which, apart from the winged males, are the only mobile stage in the insects's life-history. Attention was drawn to their behaviour and habits when attempts were made in the laboratory to rear mussel scale in large numbers.
