The results observed in pepper plants are presented in Table 1.The use of cadavers infected with EPN isolates did not show significant differences from control treatment with respect to the number of leaves per plant or the dry weight of aerial parts (F 9110 = 4.54, P≤0.0001 and F 9110 = 4.06, P≤0.0002, respectively)..

Highly Potent Extracts from Pea (Pisum sativum) and Maize are discussed from the perspective of applying EPN against soil-dwelling insect pests. (2012) Subterranean, herbivore-induced plant volatile increases biological control activity of multiple beneficial nematode species in distinct habitats. The present invention relates to methods of modifying nematode behavior using certain isolated modulator compounds. Also disclosed are methods of promoting or inhibiting reproduction in a nematode population, methods of promoting or inhibiting nematode aggregation at a first location, and methods of treating or preventing parasite infection of a plant.

Several EPN species are commercially produced and available for large-scale application. For small-scale experimental testing, EPNs can be produced in vivo and on artificial media (Kaya & Stock 1997).

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. Long-range host finding. Long-distance cues (relevant to the scale of several cm) serve to guide the nematode to areas likely to contain hosts. Putative cues include CO 2 and other compounds associated with hosts, either plant roots or insects, or in the case of EPN, the plant upon which the host is feeding. Several types of assays with numerous variants have been used to study long-distance

Different classes of insect have been identified as predators of Cylas spp [16,22,33], in different geographical regions, but the cost and technical know-how associated with their biological controls remains a challenge in the small scale farming system (Table 3) [110- 121].

International Journal of Environment Agriculture and. Nematodes are ubiquitous organisms that have a significant global impact on ecosystems, economies, agriculture, and human health. The applied importance of nematodes and the experimental tractability of many species have promoted their use as models in various research areas, including developmental biology, evolutionary biology, ecology, and animal-bacterium interactions. 1. Introduction. Entomopathogenic nematodes (EPN), belonging to the families; Steinernematidae and Heterorhabditidae, have been considered to be an effective biological-control alternative to synthetic chemical agents, for the suppression of soil-inhabiting insects (Gaugler, 2017).EPNs have been of strong commercial interest as biological insecticides as they are perceived to be a biocontrol.
