Control of the Colorado potato beetle (CPB), Leptinotarsa decemlineata (Say) (Coleoptera: Chrysomelidae), with the entomopathogenic nematode Heterorhabditis marelata Liu and Berry (Nematoda: Heterorhabditidae) was examined in the laboratory and in potato fields in north central Oregon. This research tested the hypothesis that varying nitrogen fertilizer levels would affect foliar alkaloid levels, which would stress the host, and allow increased nematode reproduction and long‐term control of the… 
Evaluation of the Effectiveness of Entomopathogens for the Control of Colorado Potato Beetle, Leptinotarsa decemlineata (Coleoptera: Chrysomelidae)
TLDR
Considering the results, the biopesticides developed from these isolates can be used safely and successfully in the pest management control programs of Colorado potato beetle.
Control of the Colorado potato beetle (Leptinotarsa decemlineata [Say]) on potato under field conditions: a comparison of the efficacy of foliar application of two strains of Steinernema feltiae (Filipjev) and spraying with thiametoxam
TLDR
Both strains of entomopathogenic nematodes showed sufficient activity when controlling larvae, but unfortunately the high price of these biological agents at the moment makes it difficult for their broader implementation in the systems of potato production.
Efficacy of the Applied Natural Enemies on the Survival of Colorado Potato Beetle Adults
TLDR
Entomopathogenic nematodes have the potential to effectively decrease the emergence of CPB adults, but further research is needed to develop the most effective application for field usage and to improve the effectiveness in the field.
MULTIFACETED BIOCONTROL METHODS AGAINST THE COLUMBIA ROOT KNOT NEMATODE, MELOIDOGYNE CHITWOODI, AND THE COLORADO POTATO BEETLE, LEPTINOTARSA DECEMLINEATA, PESTS OF POTATOES IN WASHINGTON STATE
TLDR
Whether entomopathogenic nematodes can reduce M. chitwoodi populations is determined and whether the addition of mustard seed meal amendment deters CPB oviposition is determined.
Lethal and sublethal effects of Iranian isolates of Steinernema feltiae and Heterorhabditis bacteriophora on the Colorado potato beetle, Leptinotarsa decemlineata
TLDR
Sublethal nematode concentrations caused wing deformation and delayed metamorphosis which may affect Colorado potato beetle adult fitness.
Effectiveness of entomopathogenic nematodes Steinernema feltiae and Heterorhabditis bacteriophora on the Colorado potato beetle Leptinotarsa decemlineata (Say) (Coleoptera: Chrysomelidae) under laboratory and greenhouse conditions
TLDR
It is concluded that S. feltiae has significant potential and can help in the management of the Colorado potato beetle and H. bacteriophora showed a very weak effect with L. decemlineata.
Laboratory Evaluation of Isaria fumosorosea CCM 8367 and Steinernema feltiae Ustinov against Immature Stages of the Colorado Potato Beetle
TLDR
The strain CCM 8367 of I. fumosorosea is a prospective biocontrol agent against immature stages of L. decemlineata and is recommended for higher efficacy, application together with an entomopathogenic nematode is recommended.

The aim of this study was to measure the effects of an increase in the density of the Colorado potato beetle, Leptinotarsa decemlineata (Say), on this insect and the quantity of lipid reserves of adults collected upon emergence.

TLDR
The susceptibility of the Colorado potato beetle, Leptinotarsa decemlineata (Say) to the fungal pathogen Beauveria bassiana when reared on Solanum tuberosum L,Solanum dulcamara L, Solanums carolinense L, and Lycopersicum esculentum Miller is determined, and host plant suitability declined with host plant age.

Field Evaluation of Doryphorophaga doryphorae (Diptera: Tachinidae), a Parasite, and its Host the Colorado Potato Beetle (Coleoptera: Chrysomelidae)
TLDR
There was a delay of about 7 days in fly emergence from hosts that had been parasitized as 2nd-instar rather than 4th-in star CPB larvae, which meant that as much as 39% of the emerging fly were delayed over a 7-day period.
Impact of Perillus bioculatus on the Colorado potato beetle and plant damage.
TLDR
Given the number and life stages of the predators and defoliators, the amount of prédation and defoliation was predicted and the yield loss was estimated.

TLDR
It is known that these nematodes carry a symbiotic bacterium which provides essential food for the nematode whether they are infecting a host or in culture, and this bacterium is suitable for the bacterium to multiple.
Impact of Defoliation by the Colorado Potato Beetle on Potato Yields
TLDR
Levels of defoliation and yield reduction were not correlated during the last month of the season, and the value of continuing weekly insecticide treatments during this time is called into question.
