We present here the first complete genomic Aphid lethal paralysis virus (ALPV) sequence isolated from cucumber plant RNA from East Timor. We compare it with two complete ALPV genome sequences from China, and one each from Israel, South Africa, and the United States. It most closely resembled the Chinese isolate LGH genome.

Entomopathogenic fungi (EPF) are cosmopolitan soil borne pathogens that cause epizootics in various insect orders. EPF isolates of Metarhizium brunneum and M. pinghaense have shown the potential for use as biological agents important agricultural pests. The aim current study was to test persistence on apple bark over a period three weeks, under laboratory conditions. Apple sprayed with conidial...

The cotton aphid, Aphis gossypii, is one of the most biologically diverse species of aphids; a polyphagous species in a family where most are host specialists. It is economically important and belongs to a group of closely related species that has challenged aphid taxonomy. The research presented here seeks to clarify the taxonomic relationships and status of species within the Aphid gossypii g...

The impacts of aqueous extracts from different parts (root, stem, leaf and fruit) of bitter apple Citrullus colocynthis (Cucurbitales: Cucurbitaceae), with five different concentrations, on controlling the bird cherry-oat aphid, Rhopalosiphum padi (L.) (Homoptera: Aphididae) were investigated under laboratory conditions. Results showed that the effects of the aqueous extracts from different par...

The green apple aphid (Aphis pomi De Geer 1783) and the spirea aphid (Aphis spiraecola Patch 1914) are pests of apples in North America (Foottit et al. 2006). They play a role in disease transmission (Blackman and Eastop 2000) and affect healthy growth of their hosts (Kaakeh et al. 1993). Although management regimes exist to effectively control these pests, they differ significantly because of ...
