Entomopathogenic Nematodes –
Life Cycle
Nematodes
become adults
in dead larvae
Infective juveniles are
produced when resources become limited
Nematodes release
symbiotic bacteria which
kill larvae (Xenorhabdus spp.
for Steinernematidae and
Photorhabdus spp. for
Heterorhabditidae)
Infective juveniles enter
larvae through natural
openings
Nematodes
reproduce for 2-3
generations
Thousands of infective
juveniles released in
search of new hosts

Directions for Use – General Recommendations
Treatment should be applied when pests are present
For turf applications cut the grass prior to application
Avoid applications in direct sunlight, evening applications are best
Apply in wet humid conditions
Ideally apply during rainfall or irrigate prior and after application (except for
foliage sprays where nematodes should remain on wet canopy e.g. thrips)
For soil drenches, the soil should be moist and remain as such for at least 2
weeks after application

Biological control agent containing nematodes
of the species Phasmarhabditis hermaphrodita
Infective juveniles infect through breathing pore
into the mantle
Infection causes mantle to swell as numbers
increase
Soil temperature should be between 5oC and
30oC
Slugs stop feeding and die between 4 to 21
days as nematodes spread throughout the body

Slug lifecycle
Individual slugs are capable of breeding throughout the year but do so typically in times of favourable conditions, warm and wet weather
Adults are hermaphrodites and once mated are capable of laying up to 500 eggs in batches of 20-80. Peak egg laying in Mar/Apr and Sep/Oct.
Eggs are laid in unexposed locations to avoid hot and dry environments and take 2 to 3 weeks to mature and hatch
The emerging immature stages start feeding on susceptible plant material taking one to two months to reach sexual maturity

150 years
Eggs are small and spherical (ca 1 mm). At
first white then becoming dark brown
Larvae have a cream body with no visible
legs and a dark brown head capsule. Grow to
approximately 1 cm long
Pupae are cream in colour and show adult
features such as legs and mouthparts
Adults are 0.8 – 1.0 cm in length are black
with yellow speckling on their back and have
a short snout.

150 years
Vine weevil (Otiorhyncus sulcatus) lifecycle
All adults are females and reproduce parthenogenetically
Adults emerge in May/June and lay several hundreds of eggs each around host
plants (2 - 40 cm deep)
Eggs hatch after 1-3 weeks depending on temperature and the larvae feed on the
root system
Larvae overwinter in the soil as pre-pupae and pupate in spring (some adults may
overwinter)
Life cycle is completed typically in 11-12 months, however populations in glasshouses
may have two generations per year with adults emerging as early as March.
Warmer conditions mean that they can reproduce all year round and all stages may
be present at all times, so keep monitoring.

Larvae cause extensive damage feeding on grass
roots
The turf can be easily lifted due to severed roots
Secondary damage is the most destructive; birds,
badgers and foxes are significant predators, often
tearing up turf to find the grubs
Adults do not cause any damage on turf
Without secondary damage symptoms often confused
with drought stress. If in doubt, check for grubs below

150 years
Carrot root fly lifecycle
Adult females lay eggs in May and early June on the soil surface around the plants
Eggs hatch in a few days and the maggots feed on and in the roots for about 4 weeks
Larvae pupate near the roots until July/ August when the adult flies emerge. The new flies lay more
eggs, which again mature to maggots. This second generation causes plant damage in August/
September
Larvae that develop in Autumn will spend the winter as pupae in the soil or as maggots in the roots
Larvae from the second generation cause the greatest damage. There can be a third generation in
late Autumn (November). Over-wintering carrots are particularly susceptible to this generation

Susceptible plant types
Attacks a wide range of cultivated plants, including:
Carrot
Parsnip
Parsley
Celery
Carrot root fly (Psila rosae)
Damage
Larvae tunnel inside tap roots of umbelliferous plants, leaving behind a rust-coloured material
Larval feeding causes scars and distortions of roots leading to a reduced yield and allows an entry point for secondary pathogens that cause decay
Affected plants, with large infestations, may become yellow, stunted, and die. However, more often the plant tops continue to look healthy. Maggots often continue to feed in stored carrots
Seedlings can be killed

Cabbage root fly (Delia radicum)
Larvae are yellowish or white and up to 9 mm long

along the back of the abdomen, red eyes and about 6-7 mm long

Cabbage root fly lifecycle
An adult female has a short lifespan (12 to 15 days at 20°C) and lays about 150 eggs. Laying begins
about 3 days after the adults have emerged from the ground in spring
Eggs are deposited in the ground in small clusters in the immediate vicinity of the plant stem and hatch
4-6 days later at 15-20°C. High temperature leads to high mortality of eggs and young larvae
Once the egg has hatched, the larva buries itself in the ground and penetrates the roots where it forms
galleries in the most tender parts. Once the larva is fully developed (about 3 weeks depending on
temperature), it leaves the plant and pupates
Nemasys®
Natural Fruit & Veg Protection
Pupae development lasts about 20 days. When soil temperature
is above 22 C in the summer, pupae remain in a state of rest
(quiescence). Pupae enter diapause in the autumn and
reassume their development in spring when the soil warms up
Three to four generations per year, from the beginning of April to
October. Precise timings vary from region to region and year to
year

Cutworms are soil dwelling caterpillars that cut down young stems as they feed at or below the soil surface. There are also species of climbing cutworms that feed above ground.
Eggs are white/yellow in colour and measure about 0.5 mm in diameter.
Larvae typically measure 2 to 3 mm in length when newly hatched. Species can be quite distinct from each other and their coloration can vary (pink, brown, gray, black, spotted, stripped). Fully developed caterpillars may reach 50 mm in length.
Pupae are red/brown in colour and measure about 20 mm in length.
Adults are about 20 mm long with a 40mm wingspan.

Cutworm lifecycle
After 4-12 days, eggs hatch and larvae develop through 6 or 7 larval instars,
which may take from 15 days at 26˚C to 3 months depending on temperature
and species.
Larvae pupate in the soil and adults emerge after around 11-13 days at 25˚C,
and typically live for around 4-10 days. They may go through as many as 3
generations per year depending on temperature.
Females begin laying eggs 2-5 days after
emerging.
Each female can lay hundreds of eggs singly or in
small batches, typically on low-growing plants or
soil.

The pupa measures 20 mm and is contained within a white cocoon which darkens to brown/ black
Adult forewings are gold/ bronze, typically with two silver spots although possibly just one, and the hindwings are pale. The wingspan measures about 40 mm
