Temperature Effects on Development of and .

and are virulent species that can overcome root-knot nematode resistance in economically important crops. Our objectives were to determine the effects of temperature on the infectivity of second-stage juveniles (J2) of these two species and determine differences in duration and thermal-time requirements (degree-days [DD]) to complete their developmental cycle. Florida isolates of .

Slight induction and strong inhibition of hatching by short-chain molecules released by different plant species.

New management tools are necessary to reduce the damage caused by the soybean cyst nematode (SCN), . Identification of molecules that can stimulate second-stage juveniles (J2) hatching in an environment without food may contribute to that. In in vitro experiments, we evaluate the effect of volatile organic compounds (VOCs) released by soybean (), bean (), ryegrass (), and alfalfa () on egg hatching.
