Isolation and characterization of polymorphic microsatellite loci in Aleurodicus dispersus (Hemiptera, Aleyrodidae). | Ten microsatellite markers were isolated and characterized from Aleurodicus dispersus, the spiraling whitefly, an exotic pest species that is considered to be one of the most serious agricultural pests on Hainan Island, China. The polymorphism of these loci was examined in individual whiteflies from Hainan Island and from the Canary Islands. All loci were polymorphic, with two to four alleles per locus. Mean observed and expected heterozygosity values were 0.773 and 0.585, respectively. T ... | 2011 | 22009865 |
microbial control of the invasive spiraling whitefly on cassava with entomopathogenic fungi. | the entomopathogenic fungi beauveria bassiana, metarhizium anisopliae, lecanicillium lecanii and isaria fumosorosea were tested for their efficacy in managing the exotic spiraling whitefly aleurodicus dispersus (hemiptera, aleyrodidae) on cassava (manihot esculenta) during 2 seasons (2011-2012 and 2012-2013). the fungi i. fumosorosea and l. lecanii exhibited promising levels of control (> 70% mortality of the a. dispersus population). the percent mortality increased over time in both seasons. ap ... | 2017 | 26691465 |
pathogenicity, ovicidal action, and median lethal concentrations (lc 50 ) of entomopathogenic fungi against exotic spiralling whitefly, aleurodicus dispersus russell. | biological control using entomopathogenic fungi could be a promising alternative to chemical control. entomopathogenic fungi, beauveria bassiana (balsamo) vuillemin, metarhizium anisopliae (metschnikoff) sorokin, lecanicillium lecanii (zimmerm.) zare and gams, and paecilomyces fumosoroseus (wize) brown and smith, were tested for their pathogenicity, ovicidal effect, and median lethal concentrations (lc50) against exotic spiralling whitefly, aleurodicus dispersus russell. the applications were ma ... | 2013 | 24455279 |
discovery of a new world ladybird beetle nephaspis indus gordon, 1996 (coleoptera: coccinellidae: scymnini) on the island of taiwan. | nephaspis indus gordon, 1996 was imported into taiwan from hawaii in 1990 as a biological control agent for the spiralling whitefly, aleurodicus dispersus russell, 1965 (hemiptera: aleyrodidae). however, its establishment was not known prior to this study. | 2016 | 27932925 |
distribution and biology of mallada desjardinsi (neuroptera: chrysopidae) in india and its predatory potential against aleurodicus dispersus (hemiptera: aleyrodidae). | in this study, we report the prevalence of mallada desjardinsi (navas) in seven geographical regions of india and provide the first report of its kind outlining the preying of all stages of the spiraling whitefly, aleurodicus dispersus russell, by m. desjardinsi sampling was conducted in seven regions of two provinces in india, bengaluru (karnataka) and tiruppur (tamil nadu), which demonstrated that m. desjardinsi populations were most dense at the former and least at the later. to the best of o ... | 2016 | 27417642 |
the complete mitochondrial genome of a spiraling whitefly, aleurodicus dispersus russell (hemiptera: aleyrodidae). | we report the complete mitochondrial genome (mitogenome) of a spiraling whitefly, aleurodicus dispersus (hemiptera: aleyrodidae). the 16 170 bp long genome consists of 13 protein-coding genes, 20 transfer rnas, 2 ribosomal rnas, and a control region. the a. dispersus mitogenome also includes a cytb-like non-coding region and shows several variations relative to the typical insect mitogenome. a phylogenetic tree has been constructed using the 13 protein-coding genes of 12 related species from hem ... | 2017 | 26679039 |
influence of constant temperature on development and reproduction of encarsia guadeloupae viggiani (hymenoptera: aphelinidae), a parasitoid of the spiraling whitefly aleurodicus dispersus russell (hemiptera: aleyrodidae). | encarsia guadeloupae viggiani is an important parasitoid of aleurodicus dispersus russell. the effects of temperature (16, 20, 24, 28, and 32°c) on development and reproduction of this parasitoid on a. dispersus were studied in laboratory experiments. the developmental duration of e. guadeloupae varied from 14.9 (32°c) to 54.4 days (16°c). the developmental threshold and thermal constant for an entire generation were 10.52°c and 308.85 degree-days, respectively. the highest survival rate (63.8%) ... | 2015 | 26013134 |
field evaluation of different wavelengths light-emitting diodes as attractants for adult aleurodicus dispersus russell (hemiptera: aleyrodidae). | in recent years, light traps with light-emitting diodes (leds) have been widely used in integrated pest management. the spiralling whitefly, aleurodicus dispersus russell, a highly invasive pest which causes heavy damage to fruit trees and ornamental plants, exhibits positive phototaxis, and light trap is the most appropriate tool for monitoring. we evaluated the use of leds as an inexpensive light source and examined the relationship between the captured number and the population density of adu ... | 2014 | 27193950 |
nymphal antennae and antennal sensilla in aleurodicus dispersus (hemiptera: aleyrodidae). | whiteflies have distinct nymphal stages: their first stage is mobile, whereas the later immature stages are sessile. the developmental and structural changes of antennae and antennal sensilla in whiteflies during these stages have rarely been investigated. this paper describes the morphology of antennae and antennal sensilla in four nymphal stages of aleurodicus dispersus based on scanning electron microscopy. there were significant differences found in shape and length of the antennae, and diff ... | 2014 | 24871255 |
antennal sensilla of female encarsia guadeloupae viggiani (hymenoptera: aphelinidae), a nymphal parasitoid of the spiraling whitefly aleurodicus dispersus (hemiptera: aleyrodidae). | encarsia guadeloupae viggiani (hymenoptera: aphelinidae) is a minute, obligate endoparasitoid against the spiraling whitefly aleurodicus dispersus nymph. the external morphology and distribution of the antennal sensilla of female e. guadeloupae were observed by scanning electron microscopy. antennae of female e. guadeloupae were geniculate in shape, which consist of scape with a radicula, pedicel, and flagellum. eight morphological sensilla types were recorded in the females: nonporous sensilla ... | 2013 | 23036370 |
