Many years ago i was an industrious collector of scale insects and mealy-bugs, especially in jamaica. I found them in great abundance on cultivated plants, and obtained many species. When recently travelling in the oriental tropics, i was struck by the relative scarcity of these insects, and the occurrence of various well-known injurious forms only in small patches or isolated individuals.
Scale insects may attack roots, bark, leaves, twigs, or fruits of plants. Serious plant pests are the san jose scale, the oystershell scale, the scurfy scale, and the purple and red scale of citrus. Other species—including the cochineal insect, the lac insect, and the ground pearls—have some commercial value.
Soft scale insects is intended to be a further step towards providing comprehensive information on soft scale insects. Four or five decades ago, entomologists embarking on a study on soft scale insects would have encountered a scarcity of general text books or comprehensive treatise of the family, as a starting point for their research.
There is little information on the distribution and pest status of soft scale insects (hemiptera: coccoidea: coccidae) in vineyards in australia despite the potential of this group to spread ampeloviruses and directly damage vines. A survey of coccid species in the main vineyard regions was therefore undertaken.
The coccus scale insects of macaranga are taxonomically challenging even for coccid taxonomists. Under field conditions, identification is virtually impossible partly due to their small size and because species boundaries have yet to be worked out, with many species unnamed.

This paper is aimed to revise, update and unify coccid terminology, and to compare the significance of some terms with analogous ones in other groups of insects. In this paper we shall discuss the basic terminology for (1) genetic systems, (2) partheno-genesis, (3) strategy of birth and (4) “dizygotic” development of scale insects.
At that time only one other species was known in the genus icerya (maskell 1878). This scale is apparently native to australia and made its way to california on acacia plants around 1868 or 1869 and in about ten years was causing damage to citrus groves in southern.
Sition of aqueous extracts of the five scale insect species have been published elsewhere [14].

The present paper continues a series of the author's publications on the cytogenetics and reproductive biology of scale insects from different regions of the world (gavrilov 2004, 2007, gavrilov.
Approximately 16,000 species are described within the sternorrhyncha suborder and 7,500 out of that number are scale insects.
Macadamia felted coccid is usually controlled using insecticides (insect growth regulators) and horticultural oils (wright and conant 2009).
Diaspididae scale is commonly known as hard scale and is a more host specific insect. Coccid scale is commonly known as soft scale and is more widespread. As it is the more common scale, this article will discuss soft scale on plants and coccid scale control.
Scale insects are small insects of the order hemiptera, suborder sternorrhyncha. Of dramatically variable appearance and extreme sexual dimorphism, they comprise the superfamily coccoidea. Adult females typically have soft bodies and no limbs, and are concealed underneath domed scales, extruding quantities of wax for protection. Some species are hermaphroditic, with a combined ovotestis instead of separate ovaries and testes. Males, in the species where they occur, have legs and sometimes wings,.
Most plant-ants cultivate mealybugs (pseudococcidae) and/or soft scale insects ( coccidae, or coccids) within the cavities of the myrmecophyte host (longino.
Scale insects, also of the order homoptera, produce waxy, round or oval scales over their bodies which protect the small, sessile insects beneath for most of their lives. Like gall-inducing insects ( see insects and other animals galls induced by cynipid wasps ), scale insects are better known for the structures they produce than the insects.
Sometimes a third player enters the story, a coccid (a soft scale insect). 2 life in hot deserts and subdeserts dixon intriguingly contrasts the effectiveness of predatory ladybirds on coccid scale pests, and their ineffectiveness on aphids.

On a global scale, more closely related plant families have more similar communities of coccid genera but the correlation is weak. Random host use could not be rejected for many coccids but randomisation tests and similarity of coccid communities on closely related plant families show that there is non‐random host use in some taxa.

Also, lebanese coccid inclusions are known to occur (or may occur being not recognized) in various collections, but are not accessible for study, thus the present paper is thought as the first contribution to the knowledge of fossil scale insects in the lower cretaceous middle east amber.
