Ecology of Longiunguis sacchari (ZEHENTNER) (Aphididae) infesting sorghums

PHYSIOLOGICAL ECOLOGY Salivary Proteins of Russian Wheat Aphid (Hemiptera: Aphididae)

Salivary secretions play critical roles in aphidÐhost plant interactions and are responsible for damage associated with aphid feeding. The objectives of this study were to evaluate aspects of salivationand the salivaryconstituentsofDiuraphis noxia(Hemiptera:Aphididae). Salivaryproteins were isolated and compared from three aphid probed diets: pure water, 15% sucrose, or amino acids (100 mM seri...

ECOLOGY AND POPULATION BIOLOGY The Ecology of Inquilinism in Communally Parasitic Tamalia Aphids (Hemiptera: Aphididae)

I report the Þrst example of communal parasitism in galling aphids and quantify the effects of gall invasion by the inquiline aphid Tamalia inquilina Miller on its host, Tamalia coweni (Cockerell). On populations of the host plants Arctostaphylos spp., both T. coweni and T. inquilina exhibited facultatively communal behavior and co-occupied galls with no apparent agonistic interactions. Althoug...

Bio-Ecology of the Louse, Upupicola upupae, Infesting the Common Hoopoe, Upupa epops

Abstract The population characteristics of the louse, Upupicola upupae (Shrank) (Mallophaga: Philopteridae: Ishnocera), infesting the Common Hoopae, Upupa epops L. (Aves: Upupiformes), were recorded during 2007-08 in District Rampur, Uttar Pradesh India. The pattern of frequency distribution of the louse conformed to the negative binomial model. The lice and its nits were reared in vitro at 35 ...

Ecology and radiation of galling aphids (Tamalia; Hemiptera: Aphididae) on their host plants (Ericaceae)

At least two species of aphid, Tamalia coweni and Tamalia dicksoni (Hemiptera: Aphididae) induce galls on the leaves of Arctostaphylos spp. shrubs (Ericaceae). These galls are frequently inhabited by at least one species of congeneric inquiline. The inquiline clade has branched off from the gall-inducing clade and appears to be radiating rapidly on different host-plants, in contrast to the gall...
