“…В Испании (провинция Альмерия) в производственных теплицах была проведена сравнительная оценка эффективности T. montdorensis и A. swirskii против оранжерейной белокрылки Trialeurodes vaporariorum и западного цветочного трипса Frankliniella occidentalis. При прочих равных условиях численность T. montdorensis на растениях была в 1.5-2 раза выше, чем численность A. swirskii (Téllez et al, 2020).…”

The subtropical mite species Transeius montdorensis is widely used to control thrips and other sucking pests in European countries. To develop a domestic technology for the mass rearing of T. montdorensis, its biotic potential has been evaluated under large scale production. The growth rate of T. montdorensis is 0.19±0.017, the doubling time is 4.7±0.29 days at 26–27 °C. In the tested range of mite densities (5–80 ind./ml), the growth rate tends to decrease as the density increases. This trend can be approximated by a logarithmic curve. The density 60–80 ind./ml causes not only a significant drop in the population growth rate but also the decrease in range of its fluctuations. Higher fluctuations of growth rate at lower predator densities (5–15 ind./ml) are probably due to the fact that, in some containers, the predator is unable to hold back outbreaks of its prey (the flour mite Tyrophagus entomophagus). As a result, the prey overpopulates the substrate, which causes its contamination by waste products stimulating microflora development. The growth rate in the density range of 5–15 ind./ml is lower than expected and does not differ significantly from that in the range of 20–30 ind./ml. This indicates that the prey uncontrolled growth inhibit the reproduction of T. montdorensis. The population doubling time is a reliable indicator for screening the best stock culture of T. montdorensis for its successful rearing up to density 60 ind./ml within 6–8 days, i.e., before mass growth of fungi in the substrate. The range of 20–30 ind./ml is the optimal starting density for mass rearing, and when the predator reaches a density of more than 60 ind./ml, it should be resettled or offered for sale.

“…T. montdorensis имеет широкую пищевую специализацию: питается трипсами, белокрылками и паутинными клещами (Steiner et al, 2003). В течение последних 20 лет этот вид широко используется в защите растений от трипсов на овощных и цветочных культурах (Ильницкая, 2013;Мешков, Салобукина, 2013;Steiner et al, 2003;Hatherly et al 2004;Manners et al 2013;Messelink, Kogel, 2013;van Lenteren et al, 2018). По результатам вегетационных опытов, T. montdorensis потенциально пригоден для борьбы с томатным ржавым клещом (Castañé et al, 2022) и табачной белокрылкой (Sun et al, 2022).…”

Spain is Europe’s leading exporter of tomatoes harvested in greenhouses. The production of tomatoes should be kept and increased, supported by precision agriculture to meet food and commercial demand. The wireless sensor network (WSN) has demonstrated to be a tool to provide farmers with useful information on the state of their plantations due to its practical deployment. However, in order to measure its deployment within a crop, it is necessary to know the communication coverage of the nodes that make up the network. The multipath propagation of radio waves between the transceivers of the WSN nodes inside a greenhouse is degraded and attenuated by the intricate complex of stems, branches, leaf twigs, and fruits, all randomly oriented, that block the line of sight, consequently generating a signal power loss as the distance increases. Although the COST235 (European Cooperation in Science and Technology - COST), ITU-R (International Telecommunications Union—Radiocommunication Sector), FITU-R (Fitted ITU-R), and Weisbberger models provide an explanation of the radio wave propagation in the presence of vegetation in the 2.4 GHz ICM band, some significant discrepancies were found when they are applied to field tests with tomato greenhouses. In this paper, a novel method is proposed for determining an empirical model of radio wave attenuation for vegetation in the 2.4 GHz band, which includes the vegetation height as a parameter in addition to the distance between transceivers of WNS nodes. The empirical attenuation model was obtained applying regularized regressions with a multiparametric equation using experimental signal RSSI measurements achieved by our own RSSI measurement system for our field tests in four plantations. The evaluation parameters gave 0.948 for R2, 0.946 for R2 Adj considering 5th grade polynomial (20 parameters), and 0.942 for R2, and 0.940 for R2 Adj when a reduction of parameters was applied using the cross validation (15 parameters). These results verify the rationality and reliability of the empirical model. Finally, the model was validated considering experimental data from other plantations, reaching similar results to our proposed model.
