Currently, beneficial entomopathogenic Steinernema carpocapsae nematodes have been used as successful alternatives to chemical pesticides for controlling fleas. This is because nematodes are not harmful to dogs, cats and humans, easy to apply, and can kill both larval and pupal stages of fleas with 48 hours after their application and stop the emergence of future generation adults.
Read MoreControl whiteflies with predatory mite Amblyseius swirskii in greenhouses /
Amblyseius swirskii mites are commercially available as mixed stages of adults and larvae and are currently used as a biological control agent for controlling whiteflies, which are serious pests of greenhouse plants. Both the larvae and adults of Amblyseius swirskii are very active and therefore they can quickly disperse after their application in the greenhouses to seek their hosts including whiteflies. Amblyseius swirskii mites are known to feed voraciously on all the stages of whiteflies. As these mites can eat over 10 whiteflies or eggs or nymphs per day, they can eliminate whitefly populations quickly in the greenhouses.

Biological control of spider mites can be achieved by using the predatory insects including green lacewing, ladybugs, minute pirate bugs and gall midges, and predatory mites including Amblyseius andersoni can directly feed on spider mites and reduce their population below their economic damage level. Please click on each predatory insect and mites for detailed information on their rate and timing of of application for the effective control spider mites in your greenhouse and gardens.

Small hive beetles, Aethina tumida are the most devastating insect pest of honey bee (Aphis mellifera) hives (Photo 1). Both adults and larvae of small hive beetle cause direct and indirect damages to honeybees. In case of direct damage, larvae of small hive beetle directly feed on the honeybee brood, honey. pollen and destroy honeycombs. In case of indirect damage, both adults and larvae of small hive beetle spread yeast, Kodamaea ohmeri into the colony and yeast that grows on the honeycombs causes fermentation of honey, which is not suitable for human consumption or as the food for honeybees.

Plant nematodes are microscopic unsegmented roundworms (Photo 1) that cause severe damage to many plant species. A handful soil may contain several different species of plant nematodes including root-knot (Meloidogyne spp.), Sting (Belonolaimus spp.), lance (Hoplolaimus spp.), root- lesion (Pratylenchus spp.), ring (Mesocriconema spp.), stubby-root (Paratrichodorus spp.), spiral (Helicotylenchus spp.), dagger (Xiphinema spp.) and cyst (Heterodera spp.) nematodes (Photo 1). Of these nematode species, root- nematode is considered the most economically important pests of many plant species including field crops (cotton, peanut, soybean, corn etc) and vegetables (tomato, peppers, cucumbers, eggplants etc).

Japanese beetles (Popillia japonica) are one of the most damaging insect pests of many agricultural and horticultural crops, ornamental plants and turfgrasses. Larvae of Japanese beetles are also called as grubs that mainly damage plant roots whereas their adults damage only aboveground plant parts like flowers, fruits, leaves and twigs.

The fall armyworm, Spodoptera frugiperda is one of the most economically important pests of different plant species including corn, sorghum, forage, and turf grasses. Although fall armyworm larvae actively damage crops throughout the United States during growing season, they generally die when harsh winter begins in northern, central and eastern United States. Then question arises how they could re-infest fields and cause damage to the crops grown in these areas during spring and summer again.

Beneficial Steinernema carpocapsae nematodes have a potential to control tropical sod webworm, Herpetogramma phaeopteralis, one of the most damaging pests of turfgrass. Sod worms are lepidopterous insects that cause a serious damage to turfgrasses that are grown in the athletic fields, golf courses, home lawns and recreational parks. Adult moths do not cause any type of damage to turfgrass but their larval stages feed on turfgrass and reduce its aesthetic value.
