“…These findings suggest that this phenomenon is not common in the population of M. hapla used in this study. It was also reported as hardly occurring in a populations of M. javanica in Brazil by Lordello, 1962 [2] , who observed endotokia matricida (syn: matricidal hatching) only in one single female nematode. Similarly, four females of M. incognita collected in Costa Rica showed this phenomenon, each with 68, 27, 41, 39 second-stage juveniles per female and 9, 35, 23, and 29 eggs per female, second stage juveniles, and eggs, respectively [3] .…”

“…However, reports of this phenomenon are scarce for plant-parasitic nematodes. The first descriptions of matricidal hatching in the genus Meloidogyne were reported in two unknown species by Atkinson, 1889 and Nagakura, 1930 [1] , and later in M. javanica [2] and M. incognita [3] . Here, we present the first report of this phenomenon in M. hapla.…”

HIGHLIGHTS• The phenomenon of matricidal hatching was observed in Meloidogyne hapla.• Out of 974 females examined, only 14 showed this phenomenon.• Eggs at different stages of development, including first-stage juveniles within the egg and second-stage juveniles (J2) were observed inside of the female body cavity. ABSTRACT:Matricidal hatching occur when embryogenesis and egg hatching take place within the nematode uterus. This phenomenon is known to occur within entomopathogenic and free-living nematodes, but it is very uncommon among plant-parasitic nematodes. Matricidal hatching was observed in a population of Meloidogyne hapla, originally collected in Connecticut, USA and reared on tomato 'Rutgers' maintained at 24 °C for 60 days in a growth room. Out of 974 females examined, only 14 (1.4%) showed this phenomenon. Second-stage juveniles (J2) were clearly observed inside of the female body cavity. The highest numbers of J2 and eggs observed per female were 57 and 350, respectively. However, the average number of J2 per female was 13, whereas the average number of eggs per female was 90. These findings suggest that this phenomenon is not common in the population of M. hapla used in this study. To the best of our knowledge this is the first report of matricidal hatching in M. hapla.

The reproductive strategy of the pinewood nematode (PWN), Bursaphelenchus xylophilus, is sexual amphimictic and oviparous. The incidence of intrauterine egg development and hatching in plant-parasitic nematodes is not a very common phenomenon. During the process of maintaining and breeding a B. xylophilus population isolated in Spain under laboratory conditions, evidence of matricidal hatching was observed. This is the first described case of this phenomenon in this species.
