“…EPN treatments containing 0.25% or 0.5% Barricade resulted in higher mortality of Spodoptera litura F. larvae (66.0% and 61.5%, respectively) compared to EPNs mixed with tap water (29.5%); Barricade treatments also increased the mortality of P . xylostella larvae [32]. Moreover, adding Barricade to EPN treatments has been used successfully to manage stem-boring pests [31, 27, 28].…”

“…surfactants, wetting agents, oils) or humectants (e.g. Barricade ® fire gel) has been shown to improve their control efficiency against above-ground and foliar insects [30, 31, 32, 33, 27, 28]. This suggests that EPNs might be effective against a wider range of foliar insect pests when applied in conjunction with chemical additives that help to prolong their survival above ground.…”

Entomopathogenic Nematodes Combined with Adjuvants Presents a New Potential Biological Control Method for Managing the Wheat Stem Sawfly, Cephus cinctus (Hymenoptera: Cephidae)

The wheat stem sawfly, (Cephus cinctus Norton) Hymenoptera: Cephidae, has been a major pest of winter wheat and barley in the northern Great Plains for more than 100 years. The insect’s cryptic nature and lack of safe chemical control options make the wheat stem sawfly (WSS) difficult to manage; thus, biological control offers the best hope for sustainable management of WSS. Entomopathogenic nematodes (EPNs) have been used successfully against other above-ground insect pests, and adding adjuvants to sprays containing EPNs has been shown to improve their effectiveness. We tested the hypothesis that adding chemical adjuvants to sprays containing EPNs will increase the ability of EPNs to enter wheat stems and kill diapausing WSS larvae. This is the first study to test the ability of EPNs to infect the WSS, C. cinctus, and test EPNs combined with adjuvants against C. cinctus in both the laboratory and the field. Infection assays showed that three different species of EPNs caused 60–100% mortality to WSS larvae. Adding Penterra, Silwet L-77, Sunspray 11N, or Syl-Tac to solutions containing EPNs resulted in higher WSS mortality than solutions made with water alone. Field tests showed that sprays containing S. feltiae added to 0.1% Penterra increased WSS mortality up to 29.1%. These results indicate a novel control method for WSS, and represent a significant advancement in the biological control of this persistent insect pest.

“…Although it is often difficult to control this parameter in the field, one solution resides in the addition of adjuvants [ 21 , 26 , 51 , 52 , 53 ], in particular in the case of folial application of EPNs that induce a higher desiccation stress [ 54 , 55 ]. For instance, both the survival rates and infectivity of Steinernema species against two Lepidopteran pests were increased by the use of a surfactant in the nematode suspension [ 56 ]. Similarly, the negative effect of UV on nematodes can be reduced by using certain UV protectants [ 55 ].…”

Entomopathogenic nematodes from the two genera Steinernema and Heterorhabditis are widely used as biological agents against various insect pests and represent a promising alternative to replace pesticides. Efficacy and biocontrol success can be enhanced through improved understanding of their biology and ecology. Many endogenous and environmental factors influence the survival of nematodes following application, as well as their transmission success to the target species. The aim of this paper is to give an overview of the major topics currently considered to affect transmission success of these biological control agents, including interactions with insects, plants and other members of the soil biota including conspecifics.

“…For distribution of the nematodes, there are used pulverizing devices and solutions of the agents which contain adjuvants and humidifiers -surface-active substances, oils and gels, which significantly increase the efficiency of the pest control, because nematodes survive only few hours on leaves due to their quick drying out and sensitivity to ultraviolet radiation (Arthurs et al, 2016). This indicates that entomopathogenic nematodes can be efficient against a broader range of insect pests, when combined with chemical additives prolonging their survival above ground (Baur et al, 1997;Schroer et al, 2005;Ditoet al, 2016;Noosidum et al, 2016).…”

The monograph is presented in four parts. The first part is devoted to the experimental and theoretical substantiation of the criteria for safety and quality assessment of goat's milk. Parameters of subclinical mastitis in goats, comparison of methods efficiency for determination of somatic cell count in goat milk, monitoring studies of goat's and cow's milk in France and Ukraine, effect of exogenous and endogenous factors on the quality and safety of goat milk are described. The second and third parts are devoted to Coleoptera pests of stored food supplies and field crops. The forth part includes characteristics of Poaceae family members in the steppe zone of Ukraine as the main objects of farm animals feeding. Ecological characteristics of the species according to the Belgard Ekomorph System and their geographical analysis were presented. Sozological and feeding value of the species were described.
