... Close to L. leptocephalum. The female differs by the less slender head (Fig. 2), the larger clypeus, the first tergum more densely punctuated in the middle (sparsely punctated in the middle in L. leptocephalum) (Fig. 3), the third tergum pubescent only on its base, with very fine setae on the apical half (nearly completely covered with plumose setae in L. leptocephalum) (Figs 4, 5), the legs dark brown (pale brown in L. leptocephalum) (Fig. 6), the less long propodeum (Fig. 7d versus Fig. 11d). The male differs from L. leptocephalum (which is known ...

... diameter, the surface dull and completely striated (Fig. 7c). Propodeum not carinate, short (propodeal/metanotal length = 1.4), wrinkled on the basal half, micro-tessellated on the apical half (Fig. 7d). Metasoma. First tergum finely and rather densely punctuated, puncture interspaces equal two puncture diameters, the inclined base finely striate (Fig. 3b). Sides of inclined base of tergum 1 and on the bases of terga 2 to 4 with grey plumose tomentum (Fig. 4b). Middle of the tergum 3 with short weakly branched setae, without plumose hairs (Fig. 5b). Legs. Hind tibial spur with 3 long oblique teeth (Fig. ...

Some types of unmanned aerial vehicles (UDs) are called drones. These equipment's of wide versatility have been applied very recently for different tasks, among which is agriculture. From there, this technology is responding to the decline of biopolynizers in different fields around the world. The objective of this work was to analyze the implications of the use of such devices in agricultural practices in the absence of entomophiles pollinators. Methodologically it was developed as a bibliographic review, consulting databases such as Scopus, Science Direct, Google academic and others; filtering by keywords, selecting the works according to the subject of interest and the criteria of the authors. Key information from the selected documents was extracted through the documentary analysis. As a result of this review, experiences related to the application of USNs in crop fertilization were found; the literature consulted also agrees to point out that drones are a viable strategy for such activity and is at the same time a solution to the diminution of entomophiles pollinators in certain regions of the Earth. However, the reference literature, very little reports possible adverse effects, which from an ecological point of view could arise from the use of USRs in agri-food production. It is concluded that further research is needed to understand the ecological consequences that may arise from the use of the equipment.
