Heterodera carotae Pest Information
Vermiform, anterior region heavily sclerotized, strong stylet well developed. BI analysis was initiated with a random starting tree and was run with four chains for 1. The males move through the soil searching for females, and after fertilisation, the juveniles begin to develop inside the female’s body. The host range test allowed to distinguish these species from each other.
Pie chart sizes are proportional to the number of samples with a particular haplotype. It has been identified as belonging to the Goettingiana group Subbotin et al.
Some hatch soon after the cyst is formed and the second stage juveniles disperse through the soil and invade young rootlets by piercing through the epidermis with their stylets. Females White lemon shaped with large egg sac almost of the size of the female; vulval slit on cone terminus.
