## 1 Introduction  
Entomopathogenice fungi are microorganisms that specifically infect and often kill insects and other arthropods [1]. Most are nonpathogenic to plants, and relatively nontoxic to humans and animals [2]. Although fungus-infected insects can be commonly found in nature, and epizootics are observed impacting pest populations, mortality from fungal infection rarely occurs naturally at sufficiently high levels or early enough in a pest cycle to prevent economic loss. Despite their many advantages over other biological and chemical products, entomopathogenice fungi remain relatively underutilized. Approximately 60% of insect diseases are caused by pathogenic fungi [3]. The entomopathogenice fungi occurrence in the soil can depend, inter alia, on the soil type [4], the cultivated plant species [5; 6; 7], or the agricultural practices [6; 8; 9; 10; 11]. Contrary to other insect pathogenic microorganisms, entomopathogenice fungi directly infect their host through the exoskeleton. Entomopathogenic microorganisms such as viruses and bacteria, on the other hand, infect upon ingestion, through the mid-gut. Because of their low resistance to environmental changes, the degree of soil colonization by these fungi can be a reliable indicator of its condition [12]. Soil can provide a suitable environment for entomopathogenice fungi by protecting them from UV light and other biological and nonbiological factors that may limit their distribution [13]. Environmental concerns render the use of entomopathogenice fungi in the myco-biocontrol of pests highly significant. Their application as insecticides, however, presents a series of constraints, i.e., the short shelf life of the inoculum, a two- to three-week period required until mortality, the need for relatively high humidity during application, and the high cost of commercial formulations. The entomopathogenic fungi genera, including _Beauveria_, _Metarhizium_, and _Isaria_, usually colonize the soil as part of their life cycle [7; 14]. Entomopathogenic fungi are usually trapped using the following insects as baits: _Galleria mellonella_ Linnaeus (Lepidoptera: Pyralidae), _Tenebrio molitor_ Linnaeus (Coleoptera: Tenebrionidae), _or Diabrotica virgifera_ LeConte (Coleoptera: Chrysomelidae) [4; 7; 15; 16; 17; 18; 19; 20]. Terroir refers to the link between the properties of a vine (quality, taste, and style), and the natural environment in which it was produced which might influence these properties [21; 22]. Vines can be cultivated in a wide range of soils. The soil can variously influence vine behavior and grape composition, as it determines the mineral nutrition and water uptake of the plant as well as the root depth and temperature in the root area [22]. The study of soils can be approached geologically, pedagogically, and agronomically. The present study represents an examination of vine terroir soils from an agronomic (entomological) point of view. More specifically, the objective was to identify the entomopathogenic fungi distribution in soil samples from vine terroirs. To this end, we used the following stored product insects as baits: _Prostephanus truncatus_ Horn (Coleoptera: Bostrychidae), _Stiophilus zeamais_ (L.) (Coleoptera: Curculionidae), _Stiophilus oryzae_ (L.) (Coleoptera: Curcuminidae), _Rhyzopertha dominica_ [PERSON] (Coleoptera: Bostrychidae), _Tribolium confusum_ Jacquelin [PERSON] (Coleoptera: Tenebrionidae), and _Cryptolestes ferrugineus_ [PERSON] (Coleoptera: Laemophloeidae). Stored product insects were selected for this study, as they are easier to handle, faster in their development, and more cost-effective in their mass rearing, in comparison with grapevine or other pests. Soil samples were randomly collected from different points in two vine terroirs of _Vitis vinifera_ L. (Vitales: Vitaceae). The vine terroirs, Koutsoura and Petsakoi, belong to the Rouvalis Winery in the prefecture of Achaia. _V. vinifera_ plantations are the most frequent in western Achaia and render a substantial contribution to the local and national economy [23].
