چکیده
Considering the resistance development-potential of whitefly (Bemisia tabaci) against control tactics with limited action mechanisms, present study investigated accumulation two different silicon (Si) sources (SiO2 and K2SiO3) in cotton plants. The tested dose rates (0, 200, 400 mg/L) both Si were applied directly to soil or through foliar application on leaves. Moreover, a laboratory bioassay was also conducted evaluate performance oviposition preference biology B. tabaci. A significantly higher accumulation, reduction preference, prolonged developmental period all nymphs total life cycle tabaci observed case foliar-applied silicon. Similarly, among sources, significant decline number oviposited eggs delay SiO2, followed by K2SiO3. plants subjected SiO2 treatments possessed contents their leaves than K2SiO3 treated results further revealed that showed promising at concentrations regarding parameters fecundity, Our strongly suggest emerging pest strategies lies use Si, which can be incorporated integrated management programs due its safety for humans beneficial insect fauna.
