Are Entomopathogenic Nematodes Effective Biological Control Agents Against the Carob Moth, Ectomyelois ceratoniae?

of exploring effective control methods, especially environmental friendly approaches. Entomopathogenic nematodes (EPNs) are a group of biological control agents that actively search for the host, including those in a cryptic habitat like the carob moth larvae within infested fruits. Here, we assumed that treatment of the infested and dropped fruits with EPNs may provide new insight into the management of the carob moth. Three species of EPNs, Steinernema feltiae, S

Molecular Identification of Entomopathogenic Nematode Isolates from the Philippines and their Biological Control Potential Against Lepidopteran Pests of Corn

In search for local entomopathogenic nematode (EPN) species as a biological control agent of lepidopterous insect pests of corn, a survey for EPN in the major islands in the Philippines was conducted. Seven EPN populations from 279 soil samples were isolated using Ostrinia furnacalis, the key target insect pest of corn in the country, as bait. Analysis of the ITS1-5.8S-ITS2 ribosomal DNA sequence revealed the presence of Steinernema abbasi, Steinernema minutum, Steinernema tami, and

effective control of S. noctilio is via the biological control agent, Deladenus siricidicola (Tylenchida: Neotylenchidae). This nematode has a bicyclic life-cycle, where in the free-living phase it reproduces in wood whilst feeding on A. areolatum, while in the parasitic phase it infects S. noctilio larvae and results in sterilized females. The parasitized adult female S. noctilio becomes the natural vector that disperses D. siricidicola into new trees. In this study, the genome of D. siricidicola was

Fungal communities associated with Heterodera glycines and their potential in biological control: a current update

nematodes is as old as nematology itself, as Nathan Cobb, the father of nematology, first suggested using predatory nematodes to control plant-parasitic nematodes (Cobb, 1917). Biological control or biocontrol is scientifically attractive goal, albeit often not as commercially successful in most cases compared to chemical control methods. It has become increasingly attractive since methyl bromide has been proven harmful to the environment, livestock and humans and subsequently banned from use (Duniway

Esteya vermicola Controls the Pinewood Nematode, Bursaphelenchus xylophilus, in Pine Seedlings

Esteya vermicola (Ophiostomataceae) is an endoparasitic fungus that has great potential as a biological control agent against the pinewood nematode Bursaphelenchus xylophilus which causes pine wilt disease.We tested E. vermicola for control of pine wilt disease by spraying E. vermicola conidia on artificial wounds on pine seedlings, and the optimum E. vermicola treatment density and application time were also investigated in the greenhouse.

Several methods are studied for the control of phytonematodes (Rosa et al., 2015; Silva et al., 2014). Studies show that entomopathogenic nematodes (EPNs) have potential for biological control of these parasites (Pérez and Lewis, 2004; Lewis and Grewal, 2005). In view of the above, the objective of the present study was to evaluate the hatching, mortality and infectivity of hatched juvenis of M

Activity of Steinernema colombiense in plant-based oils

Entomopathogenic nematodes (EPNs) in the genera Steinernema and Heterorhabditis are well-known biological control agents used against many arthropod species (Campos-Herrera, 2015; Lacey et al., 2015). They selectively search for insect hosts and kill them within 2 to 3 days with the aid of mutualistic bacteria of the genera Xenorhabdus and Photorhabdus, respectively (Adams et al., 2006; Dillman et al., 2012).

An Agent-Based Metapopulation Model Simulating Virus-Based Biocontrol of Heterodera Glycines

With recently discovered soybean cyst nematode (SCN) viruses, biological control of the nematodes is a theoretical possibility. This study explores the question of what kinds of viruses would make useful biocontrol agents, taking into account evolutionary and population dynamics. An agent-based model, Soybean Cyst Nematode Simulation (SCNSim), was developed to simulate within-host virulence evolution in a virus-nematode-soybean ecosystem. SCNSim was used to predict nematode suppression under a

Specific suppressive soil has been favored by scientists because of its potential role in biological control. Usually

success of EPNs as biological control agents, field efficacy is often variable, and therefore research toward improvement is needed (Shapiro-Ilan et al., 2017). Methods to enhance biocontrol efficacy in EPNs include strain improvement as well as improving nematode production, formulation and application technology (Shapiro-Ilan et al., 2012, 2017). Clearly, to cause insect mortality, and thereby reduce pest populations, the nematodes must move to the host and successfully infect (invade) it. Therefore

The prospective of endophytic microorganisms allied with medicinal plants is disproportionally large compared to those in other biomes. The use of antagonistic microorganisms to control devastating fungal pathogens is an attractive and eco-friendly substitute for chemi­cal pesticides. Many species of actinomycetes, especially the genus Streptomyces, are well known as biocontrol agents. We investigated the culturable community composition and biological control ability of endophytic

Enhanced entomopathogenic nematode yield and fitness via addition of pulverized insect powder to solid media

Beneficial nematodes are used as biological control agents. Low-cost mass production of entomopathogenic nematodes (EPNs) is an important prerequisite toward their successful commercialization. EPNs can be grown via in vivo methods or in sold or liquid fermentation. For solid and liquid approaches, media optimization is paramount to maximizing EPN yield and quality. In solid media, the authors investigated the effects of incorporating pulverized insect powder from larvae of three insects
