| plant quality and conspecific density effects on anaphothrips obscurus (thysanoptera: thripidae) wing diphenism and population ecology. | factors that influence thysanopteran wing diphenism are not well known. in these studies, the impact of food quality, mediated through nitrogen addition, and conspecific density was explored on the wing diphenism of an herbivorous thrips species (anaphothrips obscurus müller) (thysanoptera: thripidae). in the first study, nitrogen was added to timothy grass (phleum pretense l.) (poales: poaceae) transplants, and naturally occurring thrips populations were caged on the plants. thrips abundance an ... | 2010 | 20388303 |
| grass thrips (anaphothrips obscurus) (thysanoptera: thripidae) population dynamics and sampling method comparison in timothy. | sampling studies were conducted on grass thrips, anaphothrips obscurus (müller) (thysanoptera: thripidae), in timothy, phleum pratense l. these studies were used to compare the occurrence of brachypterous and macropterous thrips across sampling methods, seasons, and time of day. information about the population dynamics of this thrips was also revealed. three absolute and two relative methods were tested at three different dates within a season and three different daily times during four harvest ... | 2010 | 22546460 |
| spatial dependence, dispersion, and sequential sampling of anaphothrips obscurus (thysanoptera: thripidae) in timothy. | the spatial distribution and dispersion of anaphothrips obscurus (müller) (thysanoptera: thripidae) was examined with the goal of establishing a sequential sampling plan for this pest in timothy, phleum pratense l. (poaceae). approximately 16 different california timothy fields were sampled twice yearly from 2006 to 2008 using direct observation and the beat cup method. for direct observation, the number of thrips on each leaf of the plant was counted. for the beat cup method, tillers were tappe ... | 2011 | 22251648 |
| novel insights into mitochondrial gene rearrangement in thrips (insecta: thysanoptera) from the grass thrips, anaphothrips obscurus. | we sequenced the mitochondrial (mt) genome of the grass thrips, anaphothrips obscurus, which is highly rearranged and differs from the four thrips species reported previously in the arrangement of both trna genes and a protein-coding gene, nad3, and in the copy number of the control region (cr). we reconstructed the phylogeny of the thrips with mt genome sequences, and used it as a framework to gain insights into mt genome evolution in thrips. it is evident that a. obscurus is less rearranged in ... | 2017 | 28655921 |
