Relative Effectiveness. Although P. opilio by itself appears unable to keep populations of any pest under control, it serves as one member of a complex of generalist predators that exist in many crops and that together are able to help keep pest densities low.
Aug 4, 2021 · We assembled the first harvestman draft genome for the species Phalangium opilio, which bears elongate, prehensile appendages, made possible by numerous distal articles called tarsomeres. Here, we show that the genome of P. opilio exhibits a single Hox cluster and no evidence of WGD.

Aug 3, 2021 · By Alex Viveros. Jelger Herder/Minden Pictures. Share: If there’s one defining trait of daddy longlegs, it has to be their legs. Now, scientists have shortened the legs of one species—and turned them into food-handling limbs—by tweaking the arachnids’ DNA expression.
Common harvestman. Scientific name: Phalangium opilio. The Common harvestman is familiar to us as the large, spindly spider-like creature that frequents gardens and houses. It predates on smaller invertebrates which it catches using hooks on the ends of its legs.
Phalangium opilio is a univoltine species in Europe, producing one generation per year that overwinters as eggs. Two or more generations may occur within a year in some areas of North America, in which case eggs, immatures, and adults may all overwinter.
The rapid emergence and utility of Phalangium opilio as a model for evolutionary developmental biology of arthropods serve as demonstrative evidence of a new area of study in Opiliones biology, made possible through transcriptomic data.
Feb 1, 2005 · We investigated the influence of diet on development time, survival, reproduction, and female longevity. We compared the effects of two diets, Helicoverpa zea (Boddie) eggs and Aphis glycines Matsumura, on development of P. opilio because this predator is known to feed on those prey in soybean agroecosystems.
