“…A high correlation between L. huidobrensis and early blight caused by A. solani (Soares et al, 2019), where leaf miner and the incidence of Alternaria leaf blight lesions were observed on muskmelon plants (Chandler and Thomas, 1991). Also, our results are similar to the obtained results by Soares et al, (2019), who reported a high correlation between the number of L. huidobrensis mines and A. solani spots and the dissemination of A. solani in potato plants. In addition to the previously reported roles of leaf miner adults and the number of mines in the occurrence of early blight, our results showed a high correlation between the number of larvae and minded area as both facilitate the infection by A. solani and other unstudied diseases.…”

“…Several studies confirmed the correlation between leaf miner infestation and plant disease development (Munkvold et al, 1996;Ahmed et al, 2001 andDeadman et al, 2002). A high correlation between L. huidobrensis and early blight caused by A. solani (Soares et al, 2019), where leaf miner and the incidence of Alternaria leaf blight lesions were observed on muskmelon plants (Chandler and Thomas, 1991).

“…Also, leaf perforation during L. trifolii oviposition enhanced leaf necrosis caused by Alternaria alternata in S. tuberosum L. (Deadman et al, 2002). A high correlation was detected between number of mines by L. huidobrensis and the severity of early blight caused by Alternaria solani (Soares et al, 2019). High number of leaf miner adults, larvae and mines was observed in potato fields with high early blight incidence in middle Egypt (personal observation).…”

“…Mujica and Cisneros (1997) found that L. huidobrensis reduced the yield of potato varieties (Cica, Revolution, Tomasa, Perricholi and Yungay) by 46, 53, 54, 50 and 62%, respectively. Further, Mujica and Kroschel (2013) found that each 1% increase in the percentage of foliar injury of the Canchan variety lead to a reduction in yield by 1.21, 0.46 and 0.93% in 2005, 2007, and 2008, respectively. The most important type of injury of leaf miner is produced by its larvae, which feed on leaves lower mesophyll, building cavities called mines and consequently easing bacteria and fungi entrance (Bueno et al, 2007;Palumbo, 2012 andSoares et al, 2019).…”

The early blight caused by Alternaria solani is a serious disease that threats potato plants during the growing seasons. This study investigated the relationship between leaf miner infestation and the incidence and severity of early blight in potato fields in El-Minya governorate, Egypt. An insecticide program included three different insecticides i.e., Abamectin 1.8 % EC, Fipronil 20% SC, and Imidacloprid 35%SC was applied to study its impact on leaf miner population as well as early blight incidence and severity. The leaf miner population was monitored during 2020 and 2021 growing seasons. Early blight incidence (DI), disease severity (DS), and area under the early blight progress curve (AUDPC) were estimated along with leaf miner infestation. The results showed high significant correlation between leaf miner infestation which represented by (the number of leaf miner adults, larvae, mines/leaflet and the minded leaf area) and the infection by A. solani which represented by (DI and DS of early blight) during the two growing seasons. The application of the insecticide program significantly decreased the number of leaf miner adults, mines, larvae, and minded area% as well as DI and DS of early blight. Also, it affected the correlation between the number of leaf miner adults as well as DI and DS. This study expands our knowledge about the relationship between leaf miner infestation and A. solani infection in the open potato fields and how that could be useful in setting up an effective integrated pest management program to control both leaf miner and early blight.
