Sobrevivencia de estadios biológicos de Nacobbus aberrans en condiciones de campo
[Survival of life stages of Nacobbus aberrans under field conditions]
Nematropica 31 (2), 229-235
Abstract: An experiment was established in which different life stages of Nacobbus aberrans were maintained for 12 months in microplots. Treatments consisted of: 1) eggs with gelatinous matrix (EGM), 2) eggs without gelatinous matrix (EWGM), 3) second stage juveniles (J₂), 4) juveniles of 3rd and 4th stages (J₃ J₄), 5) fragmented root-galls with all stages of the nematode (FR), and 6) controls (without nematode). The J₃-J₄ stages maintained their ability to infect tomato roots following 12 months under the experimental conditions. The FR treatment also maintained viable nematodes for up to a year, presumably those in the J₃-J₄, stages. The experiment demonstrated the likelihood that overwinter survival by J₃-J₄ stages of N. aberrans is the primary source of inoculum in following crop cycles.
