“…Under laboratory conditions indicated that “Cal JN3” was the most susceptible to infestation and “Primo Early” and “Early Urbana Y” were the most resistant cultivars to T. absoluta (Ghaderi et al, ). The present findings are in line with those of earlier studies that found the damage caused by T. absoluta on various crops to be correlated with the density of mines and larvae (Cely, Cantor, & Rodríguez, ; Cocco et al, ; Tropea Garzia et al, ). Hence, the yield loss and the direct fruit damage in tomato was a result of the percentage of leaf infestation by T. absoluta .…”

“…Tomato, Solanum lycopersicum L., is an economically important crop worldwide, ranking fourth among vegetables worldwide (Bawin et al, ; Retta & Berhe, ). One of the most destructive pests of tomato is the tomato leaf miner, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae), whose larval feeding causes 50%–100% yield losses in many areas (Cocco, Serra, Lentini, Deliperi, & Delrio, ; Tropea Garzia, Siscaro, Biondi, & Zappalà, ). This pest is native to South America, and it has spread to Afro‐Eurasian and Middle Eastern countries, including Albania, Algeria, France, Italy, Netherlands, Germany, Denmark, Greece, Cyprus, Egypt, Tunisia, Kuwait and also Iran (Baniameri & Cheraghian, ; Desneux et al, ; Urbaneja, Vercher, Navarro, Garcıa Marı, & Porcuna, ).…”

Specifying the relationship between pests and their host plants in terms of damage is one of the basic concepts of integrated pest management (IPM) programmes. The crop loss and economic injury level (EIL) of Tuta absoluta (Lepidoptera: Gelechiidae) were determined on different tomato cultivars using gain threshold (field experiment) and regression (semi‐field experiment) methods. By assessing the crop loss in 2015 and 2016, four out of seven infested tomato cultivars had a significant yield loss in terms of weight of total fruits versus the control under the open‐field conditions. However, the total number of tomato cultivars had no significant difference to control treatment. The semi‐field experiment included six treatments (0, 2, 4, 6, 8 and 10 gravid females/plant) and examined two tomato cultivars. The tomato cages with between 6 and 10 gravid females/plant showed the highest number and weight of damaged fruits. Based on pesticide control costs, the market value of tomato and the control efficacy, we determined the EIL for T. absoluta. In the field experiment, the EIL value for T. absoluta on “Petomech,” “Cal JN3,” “Rio Grande” and “Early Urbana Y” cultivars was 4.15, 4.47, 4.70 and 5.04 larvae per plant, respectively. Based on regression equations, we calculated the EIL values for T. absoluta on “Cal JN3” and “Early Urbana Y” to be 4.75 and 5.44 larvae/plant, respectively. Crop loss assessment and EIL are necessary components of cost‐effective IPM programs and can be effective tools for making decisions about the application of pesticides against T. absoluta.

“…Besides, the efficiency of chemical control of tomato leaf miner infestations has been poor because of (1) the entophytic habit of its larvae, which are protected in the leaf mesophyll or inside fruits [8,36] and (2) pest resistance against a number of applied insecticides [6,7,19]. In order to reduce the excessive use of insecticides in tomato fields, environmentally sound control strategies have been developed, including cultural control measures (e.g.…”

“…Numerous sequential sampling plans developed for arthropods in field crops have used 10% as an acceptable level of error (i.e., a and b parameters; Cusson et al 1990, Naranjo and Hutchison 1997, Cocco et al 2015. In the present study, the upper and lower stop lines for 5% and 10% error (i.e.…”

Spatially-Optimized Sequential Sampling Plan for Cabbage AphidsBrevicoryne brassicaeL. (Hemiptera: Aphididae) in Canola Fields

The cabbage aphid is a significant pest worldwide in brassica crops, including canola. This pest has shown considerable ability to develop resistance to insecticides, so these should only be applied on a "when and where needed" basis. Thus, optimized sampling plans to accurately assess cabbage aphid densities are critically important to determine the potential need for pesticide applications. In this study, we developed a spatially optimized binomial sequential sampling plan for cabbage aphids in canola fields. Based on five sampled canola fields, sampling plans were developed using 0.1, 0.2, and 0.3 proportions of plants infested as action thresholds. Average sample numbers required to make a decision ranged from 10 to 25 plants. Decreasing acceptable error from 10 to 5% was not considered practically feasible, as it substantially increased the number of samples required to reach a decision. We determined the relationship between the proportions of canola plants infested and cabbage aphid densities per plant, and proposed a spatially optimized sequential sampling plan for cabbage aphids in canola fields, in which spatial features (i.e., edge effects) and optimization of sampling effort (i.e., sequential sampling) are combined. Two forms of stratification were performed to reduce spatial variability caused by edge effects and large field sizes. Spatially optimized sampling, starting at the edge of fields, reduced spatial variability and therefore increased the accuracy of infested plant density estimates. The proposed spatially optimized sampling plan may be used to spatially target insecticide applications, resulting in cost savings, insecticide resistance mitigation, conservation of natural enemies, and reduced environmental impact.
