Allium leafminer, Phytomyza gymnostoma Loew (Diptera: Agromyzidae), is an invasive pest of allium crops in North America. Spinosyn insecticides, spinetoram and spinosad, have been effective choices for managing P. gymnostoma infestations in allium crops, but their use should be optimized for economical and resistance management purposes. In New Yor...
Wireworms have become a significant menace to cereals in the Northern Great Plains. Therefore, research toward developing effective control methods such as biological control with entomopathogenic nematodes (EPNs) is warranted. Two strains, each of two EPN species, Steinernema carpocapsae (Weiser) and Steinernema riobrave Cabanillas, Poinar, and Ra...
Pea aphid, Acyrthospihon pisum (Harris) (Hemiptera: Aphididae), is one of the key pests of pulse crops worldwide. The aphid has a broad host range, infesting crops such as faba bean, lupin, alfalfa, lentil, chickpea, grass pea, and pea. This broad host range with a complex life cycle and ability to quickly adapt to new environmental conditions make...
Wireworms are destructive soil inhabiting polyphagous pests in the Pacific Northwest and Intermountain region of the United States. Continuously increasing wireworm populations and damage in small grain crops such as spring wheat in Northern Great Plains has become a challenge for growers. Due to unavailability of effective control measures, altern...
A total of 30 different agricultural fields in the Golden Triangle Region of Montana, USA were surveyed, and 150 soil samples were evaluated for the presence of entomopathogenic nematodes (EPNs). The authors isolated EPNs from 10% of the collected samples. The recovered isolates were identified as Steinernema feltiae and Heterorhabditis bacteriopho...
Wireworms, the larval stage of click beetles (Coleoptera: Elateridae), are economically important soil-dwelling pests that attack many field crops worldwide. Wireworms have become a serious threat to spring wheat in the Northern Great Plains because of lack of effective control measures, creating a need for alternative control methods such as biolo...
Biological control agents and semiochemicals have become essential parts of the integrated pest management of insect pests over recent years, as the incorporation of semiochemicals with natural enemies and entomopathogenic microbials has gained significance. The potential of insect pheromones to attract natural enemies has mainly been established u...
The concerns over environmental risks of chemical pesticides and their consequences for insect pest control have stimulated the search for alternative control measures such as biological control by entomopathogens. Nematodes of the families Steinernematidae and Heterorhabditidae are biological control agents that are non-toxic to humans, safer to e...
Wireworms, the larvae of click beetles (Elateridae), are difficult to manage due to
their habitats and behaviour. Wireworms pose a major threat to the wheat crop in the
north‐western USA. Seed treatment with neonicotinoids, biological control management and some cultural controls are recommended to manage these pests. Trap
cropping is an emerging w...

To find the effective combinations of different persistent Entomopathogenic nematode species against L. decemlineata in Potato fields.
We are trying to understand If a specific Allium sp. is more attractive to the Allium leafminer than others and if plant size affects the preference of this pest for oviposition and feeding.
In addition, we are exploring the trap crop strategies for Allium leaminer management.
We evaluated Entomopathogenic nematodes (EPNs) against wireworms complex in Golden Triangle region of Montana. Wireworms have become a serious problem for the growers in golden triangle region (GTR) of Montana due to their hidden behavior. As, there is no effective control strategy available for wireworms, we examined the efficacy of EPNs against wireworms. EPNs are a biological control agents that can infect and kill the insects. They have a broad host range and comparatively safer to the environment. Two EPN species (Steinernema carpocapsae and Steinernema riobrave) were found killing at least 50% of test wireworm larvae under laboratory and greenhouse assays. We also found two Montana native EPN species i.e. Steinernema feltiae and Heterorhabditis bacteriophora in a survey of GTR. However, these species were not very effective against wireworm species in Montana.
