Effect of Magnetic Ferro- Solution on Some Biological Aspects of Pectinophora gossypiella (Lepidoptera: Gel.)

Abstract

Entomology Journal publishes original research papers and reviews from any entomological discipline or from directly allied fields in ecology, behavioral biology, Sea-water, magnetic, ferrous sulphate and ferric chloride , Pectinophora gossypiella, and survived, fecundity and longevityThis study investigated the effects of four compounds included Sea-water (compound-1), Seawater +magnetic + traces of (mixture ) pure ferrous sulphate (FeSo4. 7 H2O) and ferric chloride (Fe cl3. 6H2O) 1:1 (compound-2), Seawater +magnetic+ full saturation with mixture 1:1(compound-3), and match ( IGR(compound-4), on survival, and reproductive parameters of Pectinophora gossypiella, The results showd that the mortality percentages and fecundity of P. gossypiella were signifcantly afected by all treatments. In females or male , the longevity was decreased when females were exposed to (compound-2 and 3) , while, this period prolongated when treated with Match. The treatments declined significantly the times of adults longevity to 13.3, 10.0, 8.0 and 18.9 days/ female and 9.6, 7.3, 4.3 and 13.0 days / male, respectively, when the adults of P. gossypiella treated with the different compounds of Sea-water, Seawater +magnetic + traces of mixture 1:1, Seawater +magnetic+ full saturation with mixture 1:1and match (IGR), respectively, compared to 14.5days/ untreated female and 11.3 days/ untreated males.At the same times, the total eggs laid /female and hatchability percentages in adults fed on all treatments were highly significantly affected compared with the untreated adults. These data indicated that the high reduction in eggs laid by females was estimated by 68.57 and 60.73 % with Seawater + magnetic+ full saturation with mixture 1:1 and Seawater + magnetic+ traces of mixture 1:1, against, followed by 46.3% with IGR compared with control.At the same trend, was noticed in hatchability percentages.

Study the Effect of Times Exposure to Magnetic Power on Fertility and Fecundity of the Pink Bollworm, Pectinophora gossypiella (Saunders) (Lepidoptera: Gelechiidea) Adult under Laboratory Conditions

“…The obtained data are in agreement with many authors studied that the different magnetic powers against Lepidopterous insects, e.g., P. gossypiella, and Said et. al., (2017) and Earias insulana Kandil et al, (2018) they recorded the high increased in longevity females exposed to MF, on contrast the decreased in longevity males. Table 2.…”

“…2014) recorded that the adults of Euproctis pseudoconspersa (EP), highly affected when it were exposed to electromagnetic field. Walters and Carstensen (1987) on fecundity and development in Drosophila, behavior and metabolism also, exposed the pupal stage of P. gossypiella to magnetic power (28mlt) increased the mortality and reduction the percent of adult emergence (Said et al 2017), MF high effected on survivor, longevity, viability and fertility of Earias insulana (Kandil et al, 2018) also, (Pan et al, 2004), development and viability (Biljana et al, 2001), longevity and fecundity of P. gossypiella (Said et al 2017),…”

Comparison between Gamma Rays and Magnetic Flux Effects on Biological and Life Table Assays of Earias insulan (Boisd.) Eggs

“…Opposite, the eggs laying by treated adult female had severe reduction especially in high magnetic field treatment as well as fertility and fecundity. Moreover, Kandil, et al (2019) indicated that there was a significant negative effect on the reproductive process and sometimes leads to the failure of the reproduction process when the adults of P. gossypiella exposed to a magnetic field of 14&18 mlt. Also, Matar, et al (2018), stated that total eggs laid /female had a high decreasing in the number to 116.0, 79.9 and 132.0 eggs, when exposed to magnetic power (2.0, 10.0 & 24 mt), respectively, compared to 216.0 eggs in untreated.…”

The Impact of Magnetic Field on Insecticide Toxicity Measured by Biological and Biochemical Parameters of Earias insulana (Boisd)

“…Some general reviews have reported on the effects and mechanisms of EMF exposure on insects [Hussein et al, 2015], new findings in the cell biochemistry of insects, and the impact of changes in insects' biology or population dynamics [Kandil et al, 2018, 2019]. Additional negative effects that were described in different studies included the direct exposure of adult Pectinophora gossypiella and E. insulana to magnetic power (42, 12, and 4.2 mT), showing that some biological aspects were affected, such as development time, malformation of different stages, and generation times [Said et al, 2017; Kandil et al, 2018, 2019], along with reduced reproductive ability and fertility [Balmori, 2015], lethargy, failure to find food, escape behavior, disturbance of the sense of orientation, and reduced reaction speed. The effect of MF on insect behavior, biochemical parameters, and the morphology of Lepidoptera, Spodoptera litouralles , Pectinophora gossypiella , and E. insulana were studied [Hussein et al, 2014; Balmori, 2015; Kandil et al, 2018].…”
