TABLE OF CONTENTS
AAdaline Adult
Biologicals
AMBLYLINE
Amblyline contains the predatory mite Neoseiulus cucumeris
formerly known as and still often referred to as Amblyseius
cucumeris. This species has long been known to control the
larvae of thrips, making it one of the most recognized beneficial
insects. In addition to its use against thrips, it is widely used to
fight tarsonemids. With the ability to feed on pollen, it can be
established more easily in pollen rich crops. The use of breeding
sachets will facilitate its establishment for optimal preventative
use.
ANDERLINE
Anderline contains the predatory mite, Amblyseius andersoni.
This species feeds on a wide spectrum of plant feeding mites and
small insects, as well as pollen. This wide spectrum of activity
makes establishing A. andersoni easier than other species, as the
mites will establish themselves faster on crops that are abundant
in pollen, as an alternative source of food. It is an ideal species
for using in a preventative strategy against mites. They will take
longer to establish themselves on pollen-free crops, but sachets
can be used to release mites preventatively or where there is no
pollen.
CALIFORNILINE+
Californiline contains the generalist predatory mite, Amblyseius
californicus. This mite species feeds on a wide spectrum of
phytophagous mites and small insects, as well as pollen. It is also
more resistant to high temperatures, low humidity and certain
commonly used insecticides than some other species of mite
so can survive longer in crops under less favourable conditions.
These characteristics make it an excellent ally for preventative
pest control under difcult conditions.
CHRYSOLINE+
Chrysoline contains the the generalist aphid predator Chrysoperla
carnea, known as lacewings. The larvae are excellent predators
of aphids and other soft-bodied pest species. Adults look for
aphid colonies and then lay their eggs nearby. The hatching
larvae will remain close to feed on the aphids. This solution is
recommended for use on outbreaks, given their high predation
capacity: one larva can consume up to 200 aphids.
EXHIBITLINE SF
Exhibitline Sf contains the entomopathogenic nematode
Steinernema feltiae. This can sprayed on the ground or compost
to control fungus gnat larvae, shore fly larvae and thrips pupae.
When sprayed on leaves, Exhibitline Sf is used to control thrips
larvae and some leafminers.

HYPOLINE
The beneficial contained in Hypoline, Hypoapsis miles (also
known as Stratiolaelaps scimitus) is a predatory mite living in
soil. These mites are efective against fungus gnats, shore flies
and thrips pupae which have fallen to the ground. The mite ivs
very quick to establish. It is also resistant to high temperatures,
low humidity and certain commonly used insecticides so can
survive in crops under less favourable conditions.
ORLINE I
Orius insidiosus is a standard corrective treatment for Thrips
in glasshouse crops. The main target is Western Flower Thrips
(Frankliniella occidentalis) but it is a very active generalist predator
that can consume other pests such as other thrips species, mites,
moth eggs and small caterpillars.
PHYTOLINE+
Phytoline contains the predatory mite, Phytoseiulus persimilis.
This species is an active hunter and has become a widely used
solution in many crops. It develops twice as fast as spider mites if
humidity conditions exceed 60% (unfavourable to phytophagous
mites, favourable to Phytoseiulus), thus allowing rapid control
of infestations. An adult Phytoseiulus can consume as many as
ten phytophagous mites and the reproductive cycle is only
seven days under optimal conditions. It is less efective on T.
cinnabarinus.
STARSKII®=
STARSKii contains the predatory mite Amblyseius swirskii. It is
used against whiteflies and thrips but will also be useful against
other small pests. It is ideal for protecting greenhouse crops in
hot conditions, but can also be used outdoors, as long as mean
daily temperatures exceed 20°C. Mites will establish themselves
faster on crops that are abundant in pollen, as an alternative
source of food. They will take longer to establish themselves
on pollen-free crops, but sachets can be used to release mites
preventatively or where there is no pollen. STARSKii is only
active on the young stages of whiteflies and thrips and should
not be used in poor light or at low temperatures.
TRICHOLINE TB=
Tricholine TB (with a formulation for maize called Tricholine
Corn) contains a strain of Trichogramma specifically selected
from the Trichogramma brassicae species. Although Tricho-
gramma brassicae was initially used to control the European
corn borer (Ostrinia nubilalis), it is also used on other crops where
this pest may occur (see below). It is also known to be efective
against cabbage moth (Mamestra brassicae) on some cruciferous
plants. Tricholine Corn can be used on grain corn, silage corn, sweet
corn or seed corn with appropriate doses and release strategies.
