In its large scale leaf production of ornamental plant , Lovania Nurseries uses Integrated Pest Management ( IPM ) , managing pests naturally , which is a bio - favorable glide slope to growing that focalise on managing insects , weeds and disease through a combination of cultural , physical , biologic and chemical method . These methods need to be cost good , environmentally friendly and socially acceptable . One of our independent IPM strategy is the natural use of biological command . These arrive under 3 category predators , parasites and pathogens some of which are shown below .

Aphidius colemani and Aphidius ervi are parasitoids of aphid which are very good for the prevention and low - plague management of various aphid species . These 2 - 3 millimeter mini - wasp are well used for prevent the establishment of more than 40 species of aphid . They can also tackle light to medium plague . And , if established , they can adequately protect a craw throughout the season . They are difficult to spot on the craw and very unbelievable to move around with the plants to the customer .

Aphidoletes aphidimyza is a midge whose larvae feed on over 70 aphid species , include the green peach aphid . It is the larval stage which feed on aphids and may be spotted amongst aphid infestations . adult are around 2.5 mm in length whereas larvae are 0.3 mm too 2 mm long making them hard to spot in crops .

Atheta coriaria can be used in crops such as herbs and ornamental to protect against soil and compost blighter . It is a Renaissance man tributary , but adults and young stage are peculiarly good at feed on the larva of fungus gnats .

Amblyseius andersoni , Amblyseius californicus , Phytoseiulus persimilus are used to control spider speck , all process in slightly different ways with different feeding substance abuse . Each mintage has its preferred temperatures so using them together can be a very utile tool in controlling spider pinch . They can be difficult to spot without a handwriting lens and are unbelievable to be seen on harvested crops as they prefer temperatures of > 15 degrees .

A.cucumeris is a predatory mite that is utile for the prevention , control , and direction of various thripid mintage . A. cucumeris are tough , flexible piranha that bechance to prefer thrip , mostly the green thrips stages .

A.montdorensis is a predatory touch that feed on many type of small arthropod quarry and pollen . It is idealistic for preventive control of whitefly and thripid in glasshouse . A.montdorensis is active at a broader range of temperatures than other predatory mites , making it perfect for control gadfly in challenging environmental experimental condition . A.swirskii is similar but postulate slightly higher temperatures to execute in effect .

Steinernema kraussei is an entomopathogenic nematode ( EPN : EPNs possess many desirable characteristics , such as search power of host , base hit to nontarget organism and the voltage to survive in the environment . Nematode - free-base commercial Cartesian product have become available for economic consumption against several pest all over the world during the past decade ) , which is supplied as infective juveniles that seek out their host . It is used to control black vine weevil larvae in ornamentals and berries . These nematodes can only be found with a potent microscope due to their size .

These 2 parasitical wasp hold the younger larva of greenhouse whitefly and tobacco whitefly by boniface eating and the older larva of whitefly by parasitism . The white Anglo-Saxon Protestant are approximately 0.6 mm long and are unconvincing to travel on the crop once harvested .
