Population fluctuation and faunal indices of aphids (Hemiptera, Aphididae) in peach orchards in Araucária, PR.
Aphids are sap-sucking insects that mainly attack shoots and young leaves of peach trees and many other plant species; however, knowledge of the Brazilian aphid fauna is scant. The objective of this study was to identify aphid species collected in peach orchards (Prunus persica Batsch) and to determine their faunal indices for occurrence and dominance. The experiment was conducted from July 200...
متن کاملAphids (Hemiptera, Aphididae) on ornamental plants in greenhouses in Bulgaria
Investigations on the species composition and host range of aphids on ornamental greenhouse plants in Bulgaria was conducted over a period of five years, from 2008 to 2012. Twenty greenhouses, growing ornamentals for landscaping, plant collections and other purposes were observed. They were located in the regions of Sofia, Plovdiv, Smolyan, Pavlikeni, Varna and Burgas. The total number of colle...
متن کاملECOLOGY 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...
متن کاملAphid (Hemiptera: Aphididae) species composition and potential aphid vectors of plum pox virus in Pennsylvania peach orchards.
Plum pox, an invasive disease recently identified in Pennsylvania stone fruit orchards, is caused by the aphid-transmitted Plum pox virus (genus Potyvirus, family Potyviridae, PPV). To identify potential vectors, we described the aphid species communities and the seasonal dynamics of the dominant aphid species within Pennsylvania peach orchards. Aphids were trapped weekly in 2002 and 2003 from ...
متن کاملSpecies identification of aphids (Insecta: Hemiptera: Aphididae) through DNA barcodes.
A 658-bp fragment of mitochondrial DNA from the 5' region of the mitochondrial cytochrome c oxidase 1 (COI) gene has been adopted as the standard DNA barcode region for animal life. In this study, we test its effectiveness in the discrimination of over 300 species of aphids from more than 130 genera. Most (96%) species were well differentiated, and sequence variation within species was low, ave...
