Agronomy, Journal Year: 2022, Volume and Issue: 12(9), P. 2150 - 2150

Published: Sept. 9, 2022

The fall armyworm of maize, Spodoptera frugiperda (J. E. Smith) (Lepidoptera; Noctuidae) is capable causing a 100% yield loss due to its unforeseen occurrence from the seedling cob formation stage. To manage this serious pest, maize growers are tending apply high dosage pesticides. This indiscriminate usage pesticides has resulted in an unacceptable amount insect resurgence harming production and consumption. In review, we prepared list practical pest management options, including host plant resistance, agronomical, cultural, biological, botanical, chemical, biotechnology approaches. It was found that cultivation tolerant genotypes, adjusting sowing windows, practicing specific intercultural cropping systems measures addition chemical non-chemical strategies showed encouraging results for sustainable armyworm, which could protect crop. review highlights novel successful options advocated various parts world. Recommendations documented paper would certainly pave way other concerned crops.

Formulation of nanopesticide with graphene oxide as the nanocarrier of pyrethroid pesticide and its application in spider mite control

RSC Advances, Journal Year: 2021, Volume and Issue: 11(57), P. 36089 - 36097

Published: Jan. 1, 2021

Nanopesticides with controlled release can achieve more effective utilization of pesticides. Here, to enhance the adsorption pesticides onto target organisms, formulation temperature-responsive was proposed by combing graphene oxide (GO) and existing pyrethroid (cyhalothrin, bifenthrin fenpropathrin). Pesticides were loaded GO nanosheets as a carrier via simple physisorption process, GO-pesticide nanocomposites exhibited excellent storage stability, which are vital importance practical application. Furthermore, we assessed bioactivity against spider mites (Tetranychus urticae Koch) indoors in field. As result, had many folds higher than individual pesticides, could be adsorbed on cuticle T. surface bean leaves highly uniform dispersibility. The easy preparation indicate their promising application potential pest control green agriculture.

Exposure to flupyradifurone affect health of biocontrol parasitoid Binodoxys communis (Hymenoptera: Braconidae) via disrupting detoxification metabolism and lipid synthesis

Ecotoxicology and Environmental Safety, Journal Year: 2023, Volume and Issue: 255, P. 114785 - 114785

Published: March 17, 2023

Assessing the potential effects of insecticides on beneficial biological control agents is key to facilitating success integrated pest management (IPM) approaches. Flupyradifurone (FPF) a novel neonicotinoid insecticide that replacing traditional neonicotinoids over large geographical range pests. Binodoxys communis, dominant parasitic natural enemy aphids. To date, no reports have addressed sublethal FPF B. communis. In this study, lethal and communis were investigated by indirect exposure larvae direct adults. Results showed LC10 LC25 had negative parameters including significantly reducing survival rate, adult longevity, parasitism emergence prolonging developmental stages from egg cocoons. addition, we observed transgenerational effect next generation (F1). RNA-Seq transcriptomic analysis identified total 1429 differentially expressed genes (DEGs) changed between FPF-treated groups. These DEGs are mainly enriched in metabolic pathways such as peroxisomes, glutamate metabolism, carbon fatty acid amino metabolism. This report first comprehensive evaluation how which adds methods assessing pesticide enemies. We speculate significant changes pathways, especially those related lipid synthesis, may be reason for weakened parasitoid biocontrol ability. The present study provides new evidence toxic environmental residue risk FPF.

Non-target effects of neurotoxic insecticides on Ganaspis cf. brasiliensis, a classical biological control agent of the spotted wing Drosophila

CABI Agriculture and Bioscience, Journal Year: 2024, Volume and Issue: 5(1)

Published: May 27, 2024

Abstract Background The spotted wing drosophila, Drosophila suzukii , is an invasive pest causing significant economic losses worldwide. Current control strategies mainly rely on insecticides, which negatively impact fruit marketability and the sustainability of integrated management (IPM) programs. In addition, pesticides can have dramatic consequences non-target species when persisting in environment at low concentrations after field applications. this context, chemical strongly interfere with releases G1 strain Asian larval parasitoid Ganaspis cf . brasiliensis currently adopted classical biological agent to manage D. infestations Methods Probit analysis was used assess baseline toxicity acetamiprid, cyazypyr, lambda-cyhalothrin, phosmet, spinosad G. adults through residual contact exposure laboratory. Then, adult parasitoids were exposed insecticide Lethal Concentrations (LC 5 LC 30 ) their mortality checked daily survival treated wasps. Results Lambda-cyhalothrin showed highest a 50 1.38 × 10 –3 g active ingredient (a.i.) /L, while cyazypyr seemed safer estimated 0.20 a.i./L without affecting sublethal doses. Spinosad phosmet significantly reduced wasp both lambda-cyhalothrin acetamiprid affected lifespan only Spinosad, caused major reductions, followed by least reduction 21.6% Conclusions Overall, study highlighted importance carefully selecting insecticides minimize adverse effects organisms. particular, most promising candidate integrate inoculative treatments. By contrast, application should be avoided alongside releases. Although less against than other tested molecules, it caution due its parasitoid.

Published: Oct. 19, 2021

The non-persistent impact of biocontrol agents can be revealed for pest control when associated entomopathogenic fungi (EPFs) negatively affect the natural enemies. In this assay, impacts Beauvaria bassiana (Balsamo) Vuillemin, and Metarhizium anisopliae (Metschnikoff) Sorokin were studied their compatibility or side effects on life table parameters an important generalist predator, Coccinella septempunctata L. results indicated non-significant both EPFs C. septempunctata. development time (egg-adult) was not significantly different in (69.79 days) treated (69.35-80.07 days). Both did induce any significant changes fecundity, adult pre-oviposition period (APOP), total preoviposition (TPOP), mean generation (T) as compared to treatment. Similarly, no difference fecundity rate observed after treatment (287.7-288.5) (290.0). highest net reproductive (R0) occurred (87.05 offspring individual-1) M. (86.31 B. beetles (76.97 individual-1). age-specific curves that had a similar treatments control. This study demonstrates anispoliae performance biology Considering with septempunctata, combinations recommended various integrated management programs.
