| how species-specific is the phoretic relationship between the broad mite, polyphagotarsonemus latus (acari: tarsonemidae), and its insect hosts? | broad mite, polyphagotarsonemus latus (acari: tarsonemidae), is a serious plant pest in tropical and subtropical regions. phoretic associations between broad mite and two genera of whiteflies (insecta: homoptera: aleyrodidae). namely bemisia and trialeurodes, have been reported from different parts of the world. our purpose was to determine the specificity of the association between the mite and its phoretic hosts. two host plants, potatoes and cucumbers, were used to study these relationships i ... | 2001 | 11523917 |
| isolation and characterization of aschersonia placenta from citrus orchards and its pathogenicity towards dialeurodes citri (ashmead). | for selecting potential biological agents to control dialeurodes citri, a major insect pest in china's citrus orchards, 75 native aschersonia isolates were selected from infected whiteflies in citrus orchards and were evaluated for virulence to third instar nymphs of d. citri at a concentration of 1 × 10(6)conidia/ml. the mortality rates of d. citri varied from 0% to 72.70%. among the 75 aschersonia isolates, three (hb10, hb12 and zj9) were the most virulent and pathogenic to d. citri and caused ... | 2013 | 23160084 |
| de novo characterization of the dialeurodes citri transcriptome: mining genes involved in stress resistance and simple sequence repeats (ssrs) discovery. | the citrus whitefly, dialeurodes citri (ashmead), is one of the three economically important whitefly species that infest citrus plants around the world; however, limited genetic research has been focused on d. citri, partly because of lack of genomic resources. in this study, we performed de novo assembly of a transcriptome using illumina paired-end sequencing technology (illumina inc., san diego, ca, usa). in total, 36,766 unigenes with a mean length of 497 bp were identified. of these unigene ... | 2014 | 24164346 |
| the effect of ultraviolet-a radiation exposure on the reproductive ability, longevity, and development of the dialeurodes citri (homoptera: aleyrodidae) f1 generation. | ultraviolet (uv) light has been used worldwide to monitor and trap insect pests. whitefly adults show conspicuous positive phototactic behavior toward uv light stimuli; however, knowledge of the effect of uv light exposure on various life-history parameters of dialeurodes citri remains limited. the present research aimed to investigate the effect of ultraviolet radiation (uv-a; long-wave) exposure on the reproduction and longevity of d. citri adults as well as the development of immature (eggs, ... | 2015 | 26314035 |
| molecular cloning, mrna expression and alternative splicing of a ryanodine receptor gene from the citrus whitefly, dialeurodes citri (ashmead). | insect ryanodine receptors are the main targets of diamide insecticides that have highly selective insecticidal activity but are less toxic to mammals. therefore, these insecticides are ideal for pest control. ryanodine receptors (ryrs) play a critical role in ca2+ signaling in muscle and non-muscle cells. in this study, we cloned the complete cdna (dcryr) of the ryr from the citrus whitefly, dialeurodes citri, a serious pest of citrus orchards in china. the open reading frame of ryr is 15,378bp ... | 2017 | 29107248 |
| distribution and sampling of the whiteflies aleurothrixus floccosus, dialeurodes citri, and parabemisia myricae (homoptera: aleyrodidae) in citrus in spain. | from 1993 to 1995 data sets were collected from four citrus groves in valencia, spain, to determine the distribution patterns of eggs and nymphs of aleurothrixus floccosus (maskell), dialeurodes citri (ashmead), and parabemisia myricae (kuwana) on leaves, and to develop reliable sampling plans for estimating densities of immature whiteflies. a. floccosus showed higher aggregation than the other two species. the dispersion index b from the taylor power law did not vary between different developin ... | 2002 | 11942753 |

| nontarget impact of spinosad gf-120 bait sprays for control of the mexican fruit fly (diptera: tephritidae) in texas citrus. | bait sprays containing the toxicant spinosad (gf-120) were applied to citrus groves in the rio grande valley of texas where mexican fruit flies were detected in surveillance traps. the sprays were applied as a supplement to a continuous sterile insect release program. sterile fly captures were 47-63% lower in the treated groves compared with control groves. eight of 10 secondary pest populations declined in the test groves subsequent to spray applications, but they also declined in the control g ... | 2005 | 16539119 |
| identification of immunity-related genes in dialeurodes citri against entomopathogenic fungus lecanicillium attenuatum by rna-seq analysis. | dialeurodes citri is a major pest in citrus producing areas, and large-scale outbreaks have occurred increasingly often in recent years. lecanicillium attenuatum is an important entomopathogenic fungus that can parasitize and kill d. citri. we separated the fungus from corpses of d. citri larvae. however, the sound immune defense system of pests makes infection by an entomopathogenic fungus difficult. here we used rna sequencing technology (rna-seq) to build a transcriptome database for d. citri ... | 2016 | 27644092 |
| seasonal occurrence of key arthropod pests and associated natural enemies in alabama satsuma citrus. | six alabama satsuma mandarin orchards (four conventionally sprayed and two unsprayed) were surveyed during 2005 and 2006 to determine the population dynamics of arthropod pests and their natural enemies. twenty-eight arthropod pest species were encountered; the major foliage pests were citrus whitefly, dialeurodes citri (ashmead); purple scale, lepidosaphes beckii (newman); glover scale, l. gloveri (packard); and citrus red mite, panonychus citri (mcgregor). two distinct population peaks were re ... | 2008 | 18419929 |
