Synthetic 2-cyano-n-(3-(n-(thiazol-2-yl) sulfamoyl) phenyl) acetamide derivatives can control Spodoptera frugiperda and then its eggs successfully with no essential impact on the flight capacity of adult parasitoids exposed to LC50s residue. The flight capacity of both Telenomus remus and Trichogramma pretiosum in treatments compared with the control is determined through an automated ESALQ model to discriminate between "flyers" and "non-flyers" through three locations, top, glue ring, and bottom. The modification of the ESALQ model depends on powering the unit with solar energy and cool white light-emitting diodes (LEDs) were added and connected with a full Arduino system to be automated automatically. Results showed that the flight capacity was significantly higher of T. remus than T. pretiosum even in treatments or control in the top location of the automated ESALQ model. Consequently, flight capacity was directly proportional to α-glycerophosphate dehydrogenase (α-GPDH) activeness and vice versa.

Spodoptera frugiperda initial larval instars can spin silk threads which would be the target of synthetic 2-Cyano-N-(3-(N-(thiazol-2-yl) sulfamoyl) phenyl) acetamide. The toxicity of synthetic derivatives (Ar1, Ar2, and Ar3) was tested against 1st and 2nd larval instars. Besides, the silk spinning ratio was examined after treatments with LC50s of certain derivatives, and different shapes of produced silk were detected in comparison with the control by SEM. In addition, malformation percentages of initial instars and latent effects were recorded. Biochemical experiments were done upon treatments with LC50s of derivatives. Results showed that Ar1 was the most effective derivative against S.frugiperda 1st and 2nd larval instars with LC50 values of 781.65 and 904.39 µLL¯¹, respectively. Spinning ratios were 6.67,13.33,26.67 and 93.33 % for Ar1, Ar2, Ar3, and control, respectively, and differences in silk strands were detected morphologically upon potent interaction with the induced treatments. Results were explained upon more biochemical analysis which showed that Ar1 recorded the highest values of total protein and total lipids, while it was the lowest in the case of enzymes such as protease, amylase, and Na+K+ATPase. It could be concluded that synthetic 2-Cyano-N-(3-(N-(thiazol-2-yl) sulfamoyl) phenyl) acetamide derivatives would be used as promising insecticides and anti-spinning silk threads compounds effectively against Spodoptera frugiperda larvae with registered high mortality percentages.

Before citrinin quantification, the data acquisition of LC-MS/MS must be performed, which includes the determination of ion monitoring reaction (SRM), finding fragmentation energies (Frag.) and collision cell energies (CE) for which the response of citrinin will be the highest for the given conditions. The best response of citrinin is obtained for Frag. of 66 V and CE of 17 and 29 V.

Phototactic behavior of both Stethorus punctillum and Scolothrips sexmaculatus was strongly affected by LEDs to the two forms of T.urticae .The attraction incidence rate ratio (IRR) was estimated of the predators .The highest attraction IRR values of S.punctillium recorded in case of T.urticae green form exposed to White LED while it was detected with S.sexmaculatus preyed on red form exposed to blue LED. Concerning voracity, it was recorded 100 % in case of predation on the green and red forms of T.urticae exposed to white and blue LEDs by Stethorus punctillum and Scolothrips sexmaculatus, respectively. Moreover, the feeding preference and the predation efficiency of certain predators on the both forms of Tetranychus urticae adult males and females which exposed to LEDs were estimated depending on direct olfaction and Y-tube olfactory test.

The drone of embedded LEDs is utilized to spread the effect of LEDs colors with their different wavelengths at the wide area vastly. LEDs were integrated with their supplements to the drone that is powered by solar energy and controlled through wireless protocol. The drone can cause high mortality ratios up to 80% as direct effect against the most certain pests. Insects with biting mouthparts such as Spodoptera littoralis was affected by white LEDs and showed 100 and 96.67% mortality against the second larval stage which infested cotton, while they caused 96.67 and 90% mortality against the fourth larval stage which infested potato. On the other hand, the both exposed larval stages of S.littoralis which infested cotton and potato were also affected by blue LEDs but lower than white LEDs. In the same trend, concerning piercing-sucking mouthparts insects, they were represente...

Resistant strains of some tetranychid mites to fenvalerate (pyrethroids) and spinosad (spinosyns) were exposed to certain colors of light emitting diodes (LEDs). Tetranychus urticae, Panonychus ulmi and Oligonychus mangiferus, were resistant to fenvalerate (pyrethroids) and spinosad (spinosyns) after selection pressure for 40 generations. Resistance ratios (RRs) were reduced after exposure to white LEDs to be lower to fenvalerate with (22.22, 31.29 and 33.76-folds) and to spinosad with (24.53, 27.08 and 46.22-folds), respectively. Furthermore, red LEDs were able to record RRs to fenvalerate with 24.56,21.50 and 34.64-folds and to spinosad with 25.06,20.41 and 29.80-folds, for the same arrangement of resistant strains of mites. LEDs can do their actions by increasing reactive oxygen scavengers (ROS) gradually. The highest increase of the reactive oxygen scavengers (APX) was recorded in the case of fenvalerate resistant strain of T.urticae with 5.08-folds, which exposed to white LEDs. While the red LEDs caused the highest APX ratio in the case of spinosad resistant strain of P.ulmi with 3.03-folds. They have been regarded highly and led to acquire susceptibility to pesticides again. Results are elevating the hope to decrease metabolic resistance with the available and the useful resource of eco-friendly implements to keep the ecosystem.

Toxicity, synergism and food consumption rate were assessed in the presence and absence of magnetic water. Without magnetic water Thiamethoxam showed higher activity with LC50 (5300 μl/l) than Diafenthiuron LC50 (6500 μl/l). With magnetic water, the toxicity clearly increased as the LC50s observed, were 1900 and 3300 μl/l of Thiamethoxam and Diafenthiuron, respectively, with synergism ratios 2.79 and 1.97% .Results revealed that mixtures of molluscicides and magnetic water could increase toxicity against M. cartusiana effectively.

Life table data were used in each sublethal treatment of parents , F2, F6 ,F10 , F20 , F30 and F40. Life cycle durations ranged from 30.73 to 16.05 days at LC50 and from 23.84 to 11.87 days at LC25 of tested pesticides,resp. Life span durations ranged from 21.71 % to-28.12 % at LC50 and from 17.84% to-30.96 % at LC25 of tested pesticides,comparing with the check. Intrinsic rate of increase (Rm) and two population growth rates(fecundity λ and vitality λ)for T.urticae (hereafter given in units λ /day)were estimated and discussed

Both of Violacene and Mertensene, were adulticides with LC 50's , 340.56 ppm and 759.23ppm, respectively, against the cattle tick; Boophilus annulatus adult females. Moreover, they can be used as ovicides. Violacene and Mertensene caused reduction in the hatchability by 96.77% and 95% respectively. Clinico-pathological studies were carried out and showed that Plocamium extract is safe to the host and none-target animals.

The goal of the journal is to advance the scientific understanding of mechanisms of toxicity. Emphasis will be placed on toxic effects observed at relevant exposures, which have direct impact on safety evaluation and risk assessment. The journal therefore welcomes papers on biology ranging from molecular and cell biology, biochemistry and physiology to ecology and environment, also systematics, microbiology, toxicology, hydrobiology, radiobiology and biotechnology. www.eajbs.eg.net Provided for non-commercial research and education use.

Mites management could be remoted even directly to cause mortality of their individuals or indirectly for biological control. Thus, smart technologies as the internet of things (IoT) with their protocols, digital systems, and artificial intelligence can play an important role to control mites and call their predators by light-emitting diodes (LEDs) and others. Moreover, advanced technologies are developed to detect and reduce the metabolic resistance of pesticides through specific tools. Therefore, the coming webinar will show all of mentioned points and explain the mode of action of innovative electronic devices that can be used against various mites.
