Most species produce between 50 and 500 eggs per female, depending on the nematode species and their environment, but some can produce more than 1,000 eggs. The length of the life cycle varies considerably, depending on nematode species, host plant, and the temperature of the habitat.
How many eggs do nematodes lay?
Multiplication and Life Cycle. Females produce 2,000 to 10,000 single-celled eggs per day. These pass in the feces and embryonate in the soil.
How often do nematodes reproduce?
These adult female worms have their eggs fertilized by male worms inside the host organism's intestines. They can produce more than 250,000 eggs every day! These eggs then exit the host organism through the host's feces. The eggs embryonate after a couple of weeks.
How many life cycles do nematodes have?
The life cycle of nematodes consists of six stages or instars: the egg (or embryo), four juvenile stages (Jl, J2, J3, J4) and the adult (Figure 6.1). All nematodes possess this basic pattern. The immature stages have been called 'juveniles' by plant nematologists and 'larvae' by animal helminthologists.
Do nematodes lay eggs?
Nematodes have well-developed reproductive systems that distinguish them as female and male nematodes. The females lay eggs, usually after fertilization by males but in some cases without fertilization. Many species lack males. Nematode eggs hatch into juveniles that resemble the adult nematodes but are smaller.
