Abstract

The object of the present study is to through light on alternatives
ways in pest management using novel insecticides with new mode of
action such as (neonicotinoids, phenylpyrazoles, diamide, phenoxypyridaloxy
derivative, and tetramic acid derivatives) in addition, study the
role of nanotechnology as an innovative technology using recently in pest
control. The five novel insecticides namely (clothianidin, fipronil,
flubendiamide, pyridalyl and spirotetramat) and chemically prepared of
silver nanoparticles using sodium citrate reduction method were evaluated
in comparison with conventional insecticide pirimiphos-methyl against
three insects attacking tomatoes cultivation under Egyptian conditions
(Bemisia tabaci, Spodoptera littoralis and Agrotis ipsilon). The
toxicological and compatibility effects and biochemical analysis were
done against laboratory and field strains of target insects after 48 hours.
The obtained results indicated that the most chosen insecticides and silver
nanoparticles exhibited effective against different insects and were
superior than conventional insecticide .The co-formulated mixture study
between organophosphate and bio-insecticides at LC25 recorded a
potentiation effect on two levels laboratory and field strain after 24&48
hours except the mixture between organophosphate and bio-insecticide
azadirachtin. The novel insecticides and silver nanoparticles didn’t show
any resistance ratio to field strain except insecticide pyridalyl in Sharkia
Governorate recorded high resistance against S.littoralis. The
organophosphate insecticide pirimiphos-methyl recorded moderate and
high resistance in case B.tabaci Qalubia strain and S.littoralis in Sharkia
strain, respectively. Regarding, the biochemical study
(acetylcholinesterase, adenosine triphosphatase, glutathione s-transferases
, phenoloxidase , total calcium ,and total protein) the results found
differences in the enzymatic and non-enzymatic components activity on
two levels laboratory and field strains.
