Abstract
Current study aimed to explore and determine untraditional methods for controlling serious pest Whiteflies Bemisia tabaci (Gennadius) infesting strawberry plants under plastic greenhouses. These methods contain study comparison between effectiveness of treatment strawberry plants Fragaria ananassa (L.) by lanthanum earth element (La) in two forms (substances), Lanthanum Chloride LaCl3 and Lanthanum Nitrate La(NO3)3 -two concentrations for each substance - on controlling B. tabaci. Experiments were carried out at two different areas (Governorates), Perkash (Giza Governorate) and Nobariya (Behera Governorate) during season 2021/2022. Results obtained at both of the two successive arias indicated to that substance Lanthanum Chloride LaCl3 was higher effectiveness than Lanthanum Nitrate La(NO3)3 on controlling successive insect, B. tabaci. Whereas results obtained indicated to that mean numbers of B. tabaci infesting strawberry plants (treatment by LaCl3) was less than mean numbers which infesting strawberry plants - treatment by La(NO3)3 - compared to control plants (strawberry plants did not treat with any substance). Results obtained also indicated to that low concentration of both of the two successive substances led to positive effect on the controlling operation of the successive insect B. tabaci while high concentration of the same substances led to negative effect of that controlling operation.
