During this survey, specimens representing at least 103 species (not all could be identified to species) within 10 families of the homopteran
suborder Auchenorrhyncha were collected.
Plant roots often grow into caves near the surface, and in some places support cave-dwelling populations of curculionid coleopterans, or sap-sucking insects, such as fulgoroid homopterans
Nonetheless, numbers of prey of this order were scarce; for instance, only one homopteran
was found attached to a leaf in July.
Interactions between extrafloral nectarines, aphids and ants: are there competition effects between plant and homopteran
Studies of ant-homopteran
mutualisms focus primarily on protection from predators as the critical means by which homopterans
benefit (Buckley 1987).
insects, 55% of the species are thought to contain more than one type of symbiont (Buchner, 1966), and both sulfide-oxidizing and methylotrophic symbionts have been found within the same bivalve host (Fisher et al.
In China, buprofezin has been reported highly effective against homopteran
pests such as the plant hopper, with very low risks to the environment and humans (Asia et al.
As a result, strains 26-O-to, 40-X-m, 43-S-d and 23-O-to isolated from homopteran
insects showed mortalities of 74, 96, 44 and 82 % respectively while HD-137, HD-1 and Bti showed 19, 83 and 95 % mortalities.
The per capita raw difference index characterizes the impacts of mantids as generally weak, except for one disproportionately strong negative effect on homopteran
prey [ILLUSTRATION FOR FIGURE 7A OMITTED].
These species are mostly flower-feeding, 65 of them being placed in Heterothrips, but 3 Brazilian species of the genus Alaucothrips are ectoparasitic on an homopteran
These natives are among the most common ants in the study areas (Ward 1987, Holway, 1998a), are all actively displaced by Argentine ants (Holway, 1998a) and, like that species, are omnivores, foraging mostly on dead arthropods, vertebrate carrion, and homopteran
exudates (Creighton 1950, P.
Behavioural aspects influencing plant virus transmission by homopteran
