| Abstract | ||||
| The adult stage of pink bollworm, Pectinophora gossypiella (Saunders) laboratory strain was exposed to magnetic fields (180 mt) at three times (12, 6 and 4 min) to study the effect of exposure time on mortality, morphological, oviposition, total eggs laid and fecundity and fertility comparison to the control under laboratory conditions 26±1° C and 75±5 RH. The results showed that the mortality percent of treated females and males during mating was high increased when exposed to magnetic power (180 mlt) for 12 min (39% mortality) followed by 22 and 13% mortality when adult exposed to 6 and 4 min, respectively. While, the female magnetized sexed with untreated male the percent mortality decreased to 3-4 times compare to anther treatment (9, 6 and 2%, respectively). Data obtained recorded that decreasd in oviposition period in the most treatments time; vice versa was happened with the adult female longevity that increased in the most treatments and contrary in male adult longevity. Eggs laying of treated adult female had significant reduction especially in magnetic field with exposed to12 and 6 minutes as well as hatchability percentages. | ||||
