“…Very often, in an attempt to control PPN, the beneficial entomopathogenic nematodes (EPN) are harmed by bionematicides or organic amendments (Bednarek and Gaugler, 1997;Somasekhar et al, 2002). Entomopathogenic nematodes are widely used by farmers and growers commercially for biological control of insect pests (Somasekhar et al, 2002). Species within the EPN genera Steinernema and Heterorhabditis (Rhabditida) are widely utilized as biocontrol agents in crop protection (Zakaria et al, 2013).…”

An organic product that consists of proprietary blend of fermentation and plant extracts with micronutrients (ACS 5075, Alltech ® , Inc., Nicholasville, KY USA) was evaluated against four strains of entomopathogenic nematodes (EPN): Steinernema feltiae (SB12(1), a wild enviroCORE strain and a commercial form e-NEMA), Steinernema carpocapsae (e-NEMA), and Heterorhabditis bacteriophora. The effects on egg hatching and survival of root-knot nematodes (RKN) were also examined. The sensitivity to the product was tested by estimating mortality and survival of EPN infective juveniles (IJ) after 24-hr treatment with four different concentrations of product (4, 7, 8, and 10%) compared with the control in a 96-well plate. There was no significant difference in survival of IJ with 4% product compared to the control. A twofold reduction in survival was observed when the EPN were exposed to the product at 7%. A 10.5% RKN egg hatching was observed when RKN were exposed to 3% ACS 5075 concentration compared to 100% hatching in the untreated. A significant (p < 0.05) reduction in juvenile survival was observed at 0.5% treatment, however, it dropped to 0 when 1% and above was used for M. javanica. Juveniles did not survive with all treatment concentrations in the case of M. incognita. The improvement in tomato plant growth and development were also observed when plants were treated with 1 and 3% ACS 5075. The product shows potential as a sustainable soil health alternative causing no harm to beneficial nematodes (EPN) at concentrations below 4%, while is promising against plant parasitic nematodes (PPN) and toward plant growth promotion.

“…(a') the attack coefficient of the spider, (N) the density of the third instar larvae of P. xylostella; (N a ) the number of the third instar larvae of P. xylostella predated by the spider; (r) the fitting coefficient; (T h, ) the handling time of spider per one P. xylostella; (N ma ) the maximum number of third instar larvae of P. xylostella predated by the spider. are increasingly needed to control insect pests (Saleh et al 2017); however, the role of natural predators of P. xylostella in agricultural ecosystems has not been taken seriously. Research and practice of biological control have concentrated mainly on parasitoids and diseases on this insect pest (Talekar and Shelton 1993).…”

ABSTRACT. Spiders, as predators of insects and other invertebrates, are an important part of the natural enemies, and they are recognized as an important biological control agent. Plutella xylostella (Linnaeus, 1758), the diamondback moth (DBM), is a well-known and destructive insect pest of brassicaceous crops worldwide. Here, we analyzed the functional responses of four spiders (Araneae) -Ebrechtella tricuspidata (Fabricius, 1775) (Thomisidae), Pardosa laura (Karsch, 1879) (Lycosidae), Pardosa astrigera (Koch, 1878) (Lycosidae), and Pardosa pseudoannulata (Bösenberg & Strand, 1906) (Lycosidae) -on P. xylostella larvae. We also analyzed intraspecific disturbances in the predation reaction and the intensity of scrambling competition of the spiders to P. xylostella larvae. Our results demonstrated that the functional responses of four spiders of different genera were in line with the Holling II model. Two Lycosidae spiders (P. astrigera and P. pseudoannulata) had the potential to control P. xylostella, and female and male spiders that belonged to the same species had different functional responses to P. xylostella.The functional responses of female predation of P. astrigena, P. laura, and P. pseudoannulata was stronger than the males, but male E. tricuspidatus had stronger functional responses to predation than females. We used the Hassell model to describe the intraspecific disturbance experiments of four spiders. There were intraspecific disturbances in the predation reactions of spiders, indicating that the predation ratio of spiders decreased in relation to the increase of its density, and with the increase of spider density, the intensity of scrambling competition of the spider increased.

“…Still, their efficiency will be tangible only when using a set of methods and minimising the use of chemicals in the process]. Other researchers use the method of biological control, which is the use of natural enemies to reduce the population density of insect pests as the main method of pest control of grain crops [SALEH et al 2017;VERMA et al 2019]. To manage wheat resistance to insect pests, resistance genes (R-genes) have been identified in varieties with resistance, which are highly effective and are actively incorporated into wheat varieties through breeding [IFTIKHAR et al 2019].…”

To improve plant resistance to pests, we analysed the impact of various agronomic practices on the number and species diversity of pests in the crops of spring wheat varieties of foreign and Kazakhstan breeding in North-Eastern Kazakhstan.The intensive development of agriculture, resulting in the new technological flow processes of wheat growing, the sowing of foreign varieties not previously cultivated under local conditions, and climate change contribute to the formation of new food chains in agrocenoses. These new food chains require the monitoring of plant-feeding species with the help of ecological approaches and techniques.Efficient protection of crops with plant feeders requires constant updating on the phytosanitary in agrocenoses. Information on phytosanitary monitoring previously carried out in the region is not available, so it became necessary to collect data and analyse the number and species composition of wheat pests, considering new foreign varieties and cultivation technology practices.The research was carried out in 2021 in typical agricultural organisations of the North-Eastern regions of Kazakhstan with different preceding crops. The vegetation period was characterised by high atmospheric temperatures and a lack of moisture in the soil in spring and summer, contributing to decreasing of plant turgor and damage resistance.Early sowing of the 'Triso' wheat variety was affected by high temperatures and lack of soil moisture in the initial stage of development, which delayed its growth and made it more susceptible to pest damage. The other varieties were sown in optimal dates recommended by regional scientific institutions.
