pisorum was compartmentalized, as follows: first instars consuming 0 to 5% of the cotyledon tissue (Damage Ratings 1 and 2); second to fourth instars consuming >5% of the cotyledon tissue (Damage Rating 3); and development to prepupa or adult with extensive damage to seed contents (Damage Ratings 4 and 5).
This idea is supported by the finding that, in the prepupa, a proleg motoneuron other than APR is active with the rhythm [ILLUSTRATION FOR FIGURE 1B OMITTED], and a putative premotor interneuron [ILLUSTRATION FOR FIGURES 1C, D OMITTED] is also active with the rhythm and induces spiking in a motoneuron that projects out [VN.sub.L].
Presenta un ciclo de vida univoltino lo que dificulta su estudio, las hembras realizan posturas en masa, los huevos son de color marron con un periodo embrionario que varia entre 19 y 24 dias, las larvas de color amarillo-crema construyen galerias en la zona subcortical del tallo y migran al sistema radical donde completan su ciclo en 240 dias, la prepupa y la pupa se desarrolla en 13 y 30 dias respectivamente (Garcia 1998, Pereira 2010).
The available pupation space is probably insufficient to allow differences in prepupa migration distances (wandering) to be resolved by simple height measures.
coli lacZ fusion-gene products, we identified the tissues that express endogenous [Beta]-galactosidase activity in the late third-instar larva, prepupa, pupa, and adult of wild-type D.
