| expressed sequence tags from cephalic chemosensory organs of the northern walnut husk fly, rhagoletis suavis, including a putative canonical odorant receptor. | rhagoletis fruit flies are important both as major agricultural pests and as model organisms for the study of adaptation to new host plants and host race formation. response to fruit odor plays a critical role in such adaptation. to better understand olfaction in rhagoletis, an expressed sequence tag (est) study was carried out on the antennae and maxillary palps of rhagoletis suavis (loew) (diptera: tephritidae), a common pest of walnuts in eastern united states. after cdna cloning and sequenci ... | 0 | 20569128 |
| big maggots dig deeper: size-dependent larval dispersal in flies. | the ability of individual animals to select habitats optimal for development and survival can be constrained by the costs of moving through the environment. animals that seek overwintering sites underground, for example, may be constrained by the energy required to burrow into the soil. we conducted field and laboratory studies to determine the relationship between individual size and overwintering site selection in the tephritid flies, rhagoletis juglandis and rhagoletis suavis. we also explore ... | 2015 | 25894095 |
| effect of surround wp on behavior and mortality of apple maggot (diptera: tephritidae). | apple maggot, rhagoletis pomonella (walsh) (diptera: tephritidae), is a key pest in apple (malus spp.) production areas located in the northeastern and midwestern united states and the eastern provinces of canada. the development of surround wp has offered a new approach for controlling apple maggot and other tephritid species, because this material is considered to be compatible with advanced integrated pest management and organic production systems. we conducted studies aimed at identifying th ... | 2010 | 20429454 |
