| development of iphiseiodes quadripilis (banks) (acari: phytoseiidae) on pollen or mite diets and predation on aculops pelekassi (keifer) (acari: eriophyidae) in the laboratory. | development and reproduction of iphiseiodes quadripilis (banks) were evaluated on single food diets of pollen (malephora crocea jacquin [ice plant] or quercus sp. [oak]), spider mites, [eutetranychus banksi (mcgregor) or panonychus citri (mcgregor) (acari: tetranychidae)], or the citrus rust mite phyllocoptruta oleivora (ashmead) (acari: eriophyidae). experiments were conducted in an environmental chamber at 28 degrees +/- 1 degrees c, 14:10 (l:d) daylength, and 45% rh. i. quadripilis completed ... | 2007 | 17349110 |
| south american spider mites: new hosts and localities. | in order to contribute to taxonomic information on tetranychid mites (acari: tetranychidae) in south america, surveys were conducted in brazil (15 states and the federal district) and uruguay (one department); 550 samples of 120 plant species were collected. tetranychid mite infestations were confirmed in 204 samples, and 22 species belonging to seven genera of the bryobiinae and tetranychinae subfamilies were identified on 58 different host plants. thirty-six new plant hosts were found in brazi ... | 2011 | 22224405 |
| evidence for host plant preference by iphiseiodes quadripilis (acari: phytoseiidae) on citrus. | in this study, we present field and laboratory evidence on the preference of iphiseiodes quadripilis (banks) for grapefruit (citrus paradisi macfadyen) leaves compared with sweet orange (citrus sinensis (l.) osbeck) leaves. this preference was confirmed in four orchards whether leaf samples were taken from either border trees of contiguous grapefruit or sweet orange or interior row trees with both citrus species in adjacent rows. iphiseiodes quadripilis was most abundant in grapefruit trees in s ... | 2006 | 16897564 |
| mites occurrence on pachira aquatica aubl. including aspects of external mouthpart morphology of brachytydeus formosa (acari: tydeidae). | pachira aquatica aubl. is commonly used as an ornamental plant in urban areas of brazil. the objective of the study was to investigate the occurrence of mites on p. aquatica, with emphasis on brachytydeus formosa (cooreman), and to describe aspects the external features of its mouthpart. the study was conducted in 2012 in jaboticabal, state of são paulo, brazil. ten trees of p. aquatica were selected for the experiment. approximately 130 leaflets were collected from each tree, which were located ... | 2016 | 26871751 |
| population fluctuation and damage caused by phytophagous mites on three rubber tree clones. | our aim was to investigate the population fluctuation and the damage caused by the phytophagous mites calacarus heveae feres, tenuipalpus heveae baker, and eutetranychus banksi (mcgregor) on clones fx 2784, fx 3864, and mdf 180 in rubber tree crops from southeastern bahia, brazil. moreover, we tested for the influence of climatic variables on occurrence patterns of these species throughout weekly samples performed from october to april. the infestation peaks was between mid-january and late febr ... | 2013 | 23949718 |
| isolation and characterization of polymorphic microsatellite markers in tetranychus urticae and cross amplification in other tetranychidae and phytoseiidae species of economic importance. | tetranychus urticae koch is a cosmopolitan phytophagous mite considered as the most polyphagous species among spider mites. population genetic studies using molecular markers such as microsatellites have proven to be extremely informative to address questions about population structure, phylogeography and host preferences. the aim of this study was to increase the available molecular tools to gain insight into the genetic structure of t. urticae populations of citrus orchards, which might help i ... | 2012 | 22349944 |
| new mite invasions in citrus in the early years of the 21st century. | several mite species commonly attack cultivated citrus around the world. up to 104 phytophagous species have been reported causing damage to leaves, buds and fruits, but only a dozen can be considered major pests requiring control measures. in recent years, several species have expanded their geographical range primarily due to the great increase in trade and travel worldwide, representing a threat to agriculture in many countries. three spider mite species (acari: tetranychidae) have recently i ... | 2013 | 23135361 |
