Can biocontrol be the game-changer in integrated pest management? A review of definitions, methods and strategies

Journal of Plant Diseases and Protection, Journal Year: 2024, Volume and Issue: 131(2), P. 265 - 291

Abstract Global agriculture is heavily dependent on sustainable plant protection. Worldwide, the concept of integrated pest management (IPM) being followed. IPM utilizes a range strategies, with chemical synthetic pesticides employed only as last resort. However, in agricultural practice, farmers continue to rely primarily this option. To further reduce dependence, new strategies are sought strengthen use biological control within approach including identification novel non-synthetic natural compounds. Here, we discuss and report state art research areas such biocontrol agents application ecological principles. These practices can help establish protection systems, greatest impact achieved when they used appropriate combinations. We highlight conditions that currently prevent or hinder increased measures. On background agroecological experiences, why additional advancements imperative more effectively break life cycles pests, diseases weeds. emphasize significance judicious technologies, adapted local conditions. Additionally, key role expertise operators implementing these their knowledge thereof.

Entomopathogens and Parasitoids Allied in Biocontrol: A Systematic Review

Pathogens, Journal Year: 2023, Volume and Issue: 12(7), P. 957 - 957

Published: July 20, 2023

Biological pest control is an environmentally friendly alternative to synthetic pesticides, using organisms such as viruses, bacteria, fungi, and parasitoids. However, efficacy variable combining different biocontrol agents could improve success rates. We conducted a systematic review of studies parasitoid with entomopathogenic microorganism, the first its kind. searched in Web Science extracted data from 49 publications matching pre-defined inclusion criteria. Combinations 36 hymenopteran parasitoids 17 microorganisms used 31 target pests were found. Trichogramma pretiosum Encarsia formosa most frequently studied parasitoids, while Beauveria bassiana, Metarhizium anisopliae, Lecanicillium muscarium, Bacillus thuringiensis var. kurstaki, Spodoptera exigua multiple nucleopolyhedrovirus, frugiperda nucleopolyhedrovirus main microbial assessed. Out parasitoid–microorganism combinations assessed laboratory experiments, thirty-eight reported compatible six incompatible. Timing dosage biopesticides played crucial role, later application appropriate minimizing adverse effects on development. More research needed assess compatibility under real-world conditions. Our provides valuable insights for researchers practitioners optimize combined use micro- macroorganisms effective control.

A parasitoid wasp allied with an entomopathogenic virus to control Tuta absoluta

Crop Protection, Journal Year: 2024, Volume and Issue: 179, P. 106617 - 106617

Published: Feb. 9, 2024

Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) is a major threat to worldwide tomato production, and sustainable management methods are needed. Betabaculovirus phoperculellae (PhopGV) the parasitoid wasp Necremnus tutae Ribes & Bernardo (Hymenoptera: Eulophidae) were identified as promising biocontrol agents of this pest. Since virus most effective against first instar larvae, whereas targets older ones, combining both could result in increased pest control. We conducted replicated semi-field experiment evaluate control efficacy N. PhopGV when used alone combination T. their compatibility over an entire growth period. Combining two achieved highest larval (−24 %) crop damage (−29 reduction cumulated experiment. However, there was no significant additive effect agents. At end trial, which coincided with emergence third generation adults, using resulted strongest adult density (−78 %), followed by virus-parasitoid (−59 %). No negative recorded on population. Our results demonstrate potential reduce population under conditions. While more research needed, our findings provide important insights into innovative agents, thereby contributing agriculture.

Efficacy of some Entomopathogenic Fungi Against Tomato Leaf Miner Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) in Iraq

IOP Conference Series Earth and Environmental Science, Journal Year: 2023, Volume and Issue: 1262(3), P. 032022 - 032022

Abstract The most important tool for biological management of several insect pests is entomopathogenic fungi. purpose this study was to compare the effectiveness Beauveria bassiana and Chaetomium globosum as agents against Tuta absoluta . According findings, B. C. globosium may be able influence T. larvae’s eggs third instar. By extending duration concentration, fungus became more active. has had greatest death rates after 7 days in instar by 83.86% 68.3% at 2 ×10 conidia mL -1 , respectively.. This score significantly differs reached 60.09%and 31.7% destruction both 3rd larvae-instar respectively. outcomes also confirmed that fungal colonies fungi isolated from leaves 10 application. highest colony percentage belongs 32.29% with a significant difference 23.26%. presence effect on eggs, larvae, pupae period development. Consequently, weight pupal influenced compared control. supremacy comparison control treatment. A gradual decrease been shown proportion two tomato 30 th days. lowest level 4.17% 9.37%
