“…Furthermore, the 42 nematode strains from various steinernematid and heterorhabditid species that were tested in the laboratory for their anti-tick activity varied in their virulence . Heterorhabditids were generally more virulent to ticks than steinernematids (Hassanain et al, 1997;Kaaya et al, 1999;Glazer et al, 2001), and strains that were highly virulent to one tick species were mostly found to be highly virulent to other tick species also (Hassanain et al, 1997;Kaaya et al, 1999;Samish and Glazer, 2001).…”

Soil texture, chemistry and moisture have a profound effect upon the activity and persistence of entomopathogenic nematodes (EPNs). Whereas nematodes' natural habitat is within the soil, ticks and other arthropod pests prefer to stay on the soil surface and under stones or leaf litter; they spend much of their life cycle in the humid environment of the soil upper layer, therefore consideration of the effect of the soil environment on nematode activity is a pre-requisite for the sucessful use of EPNs against arthropod pests. In the present study we investigated the effects of soil type, and humidity on various nematode strains and on their effectiveness against ticks. Many infective juveniles (IJs) of Steinernema carpocapsae and S. riobrave were found in the uppermost soil layer whereas the heterorhabditid strains were almost absent from the upper 6 cm of the soil profile. The IJs of S. feltiae, and the S. carpocapsae strain S-20, exhibited an intermediate behavior. It was found that the activity of IJs of S. carpocapsae in the soil upper layer (1 cm depth) was strongly affected by soil type: the greatest number of IJs were recorded from sandy loam soil; less were found in the lighter soils -'Marine sand' and 'Calcareous sandstone' -and only very few were recovered from heavy soils. Strikingly, even when the soil moisture was low and the number of nematodes found in the upper layer correspondingly low, tick mortality remained high. The results demonstrate: (a) the possible use of the nematodes as an anti-tick agent; (b) the importance of knowing the exact interaction of nematodes with the immediate environment of the pest, in order to optimize the pest-control activity of the nematode.

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.

The increasing resistance of arthropodes to pesticides, their high price, and the growing public demand for safer food and a cleaner environment are obliging animal growers to minimize the use of pesticides by introducing alternative means for tick control. The development of a biological tick control method has been neglected as compared to the control of plant pests or dipterous insects harmful to men and animals. There are abundant observations, but only a few studies have as yet been conducted on pathogens, parasitoides, and predators of ticks. A first attempt at tick biocontrol was made with the introduction of tick‐parasitic wasps from France to the USA and Russia. During the past decade, interest in developing antitick biocontrol agents such as birds (Brazil, Kenya, and Zimbabwe), parasitoides (Kenya and USA), entomopathogenic nematodes (Egypt, Israel, Guadeloupe, and USA), entomopathogenic fungi (Brazil, Cuba, Israel, Kenya, and USA), and bacteria (Brazil) has gained momentum. The reintroduction of oxpecker birds in some areas of Zimbabwe remains up to now the only known successful attempt at tick biocontrol.
