Eggs usually laid by females moist grassland the summer, singly or small clusters. Larvae roots may be transported soil of plants for planting gro...

Of the many nematode species that parasitize citrus, Tylenchulus semipenetrans is the most important on a worldwide basis. Management of the citrus nematode remains problematic as no one tactic gives adequate control of the nematode. An overall management strategy must include such components as site selection, use of non-infected nursery stock, use of at lease one post-plant nematode control t...

While fungicides may be a major mechanism for control of avocado root rot, integrated management requires several other non-fungicidal approaches which are used together to maximize root rot control. Non-fungicidal methods of control include planting clean avocado nursery stock, selecting low hazard sites, planting on mounds in more hazardous sites, preventing the introduction of P. cinnamomi, ...

Stable carbon and oxygen isotopes in the otoliths of Atlantic bluefin tuna Thunnus thynnus were used to investigate trans-Atlantic movement and natal homing behaviors. Otolith δ13C and δ18O of yearling bluefin tuna from 6 different year classes (1999 to 2004) were characterized to validate the approach and assess inter-annual variation in these markers for individuals from eastern (Mediterranea...
