Scale-eating Ladybird (Lindorus lophanthae*)
Native to Queensland and Southern Australia, Lindorus is the third ladybird product in our range and is commonly known as the scale-eating ladybird or purple scale predator. Unlike many other ladybird species, Lindorus persists throughout all seasons with several generations per year. Optimum temperature range is 18-30°C but it can tolerate a wide range of temperatures.
It is beneficial to have a resident population in the crop to minimise the risk of scale outbreaks.
Useful for: conservatories and nurseries of ornamental plants such as palms and orchids for the control of scale infestations.
For controlling: mostly suited to armoured scales (red scale, oleander scale, oriental scale, purple scale) but can also feed on soft brown scale, black scale, some wax scales, mealy bugs and moth eggs. They do not tolerate heavy secretions of honey dew. Best results are achieved by carefully sprinkling Lindorus near infestation hot spots. We suggest several releases a few weeks apart.
*This species is also known as Rhyzobius lophanthae, Scymnus lophanthae and Rhyzobius toowoombae.
Thripobius javae (T. semiluteu
s)
Thripobius is a wasp mostly used for the biological control of greenhouse thrips, Heliohthrips haemorrhoidalis, in avocado orchards and greenhouse nurseries.
Signs of a thrip infestation include whitish marks on foliage, papery and wilted leaves, defoliation and brown patches or cracks on the surface of fruits.
Wherever greenhouse thrips are actively feeding there will also be blackish spotting amongst the damage from excretory droplets.
Although most effective when used in greenhouses, this beneficial can also be effective outside depending on climate and the size of the pest population.
Useful for: greenhouse and nursery grown ornamental plants and avocado orchards.
For controlling: greenhouse thrips belonging to the sub-family Panchaetothripinae.
