“…Previous studies did not verify enhanced pest suppression when a predator and a parasitoid or two parasitoids were combined, despite the increased induced prey exposure (Bilu & Coll, 2007; Paull et al, 2012; Rocca & Messelink, 2016; La‐Spina et al, 2019). Other studies have shown increased suppression of the shared prey when a parasitoid and a predator were combined; however, this was not due to a behavioural response of the prey to avoid parasitism (Karut et al, 2018). Although our experiment did not evaluate the long‐term effect of the IGP and the dynamics of the pest and the natural enemies, the results suggest that, as the biocontrol agents used in this study share the same habitat (brassica crops) (Hosseini et al, 2012), the positive outcome on pest suppression is possible in such environments.…”

Interactions between biocontrol agents of crop pests can lead to neutral, detrimental, or improved outcomes for pest control. We investigated the existence and the nature of the additive interactions between a parasitoid, Diadegma semiclausum (Hellén) (Hymenoptera: Ichneumonidae), and two hemipteran predators, Oechalia schellenbergii Guérin-Méneville (Pentatomidae) and Nabis kinbergii Reuter (Nabidae), of the diamondback moth (DBM), Plutella xylostella (L.) (Lepidoptera: Plutellidae), under laboratory conditions. In the presence of the parasitoid, both O. schellenbergii and N. kinbergii increased predation by 56 and 66%, respectively. The escape response of the prey to avoid being parasitized (moving backwards and sometimes spinning down from the leaf on a silk thread, becoming less cryptic to the predators), may be at the basis of the enhanced predation by these predatory bugs; however, further studies are necessary to test this hypothesis. As the predators did not preferentially consume either parasitised or unparasitised larvae, coincidental intraguild predation should not affect this positive outcome in relation to DBM suppression. The findings highlight the potential utility of combining these natural enemies and may have important implications for the management of DBM in brassica crops in Australia and other multispecies systems.

“…Additionally, combining another mirid predator, Macrolophus melanotoma Costa (Hemiptera: Miridae), and the parasitoid Er. mundus supported a low number of B. tabaci in greenhouse-grown eggplant [284].…”

“…Successful biological control has been achieved in suppressing B. tabaci populations. There is a general trend in using two or more natural enemies together [277,283,284] or combining natural enemies with chemical insecticides [333,336,337]. The technologies of identification, mass production, and quality control of predators and parasitoids need to be elevated in the future.…”

Bemisia tabaci Gennadius (Hemiptera: Aleyrodidae) is among the most economically important insect pests of various vegetable crops in the Southern United States. This insect is considered a complex of at least 40 morphologically indistinguishable cryptic species. Bemisia tabaci Middle East-Asia Minor 1 (MEAM1) was initially introduced in the United States around 1985 and has since rapidly spread across the Southern United States to Texas, Arizona, and California, where extreme field outbreaks have occurred on vegetable and other crops. This pest creates extensive plant damage through direct feeding on vegetables, secreting honeydew, causing plant physiological disorders, and vectoring plant viruses. The direct and indirect plant damage in vegetable crops has resulted in enormous economic losses in the Southern United States, especially in Florida, Georgia, and Texas. Effective management of B. tabaci on vegetables relies mainly on the utilization of chemical insecticides, particularly neonicotinoids. However, B. tabaci has developed considerable resistance to most insecticides. Therefore, alternative integrated pest management (IPM) strategies are required, such as cultural control by manipulation of production practices, resistant vegetable varieties, and biological control using a suite of natural enemies for the management of the pest.

“…(Hymenoptera: Aphelinidae) are the most common parasitoids used for WFM [13,224]. In a study, augmentative release of Eretmocerus mundus Mercet and Macrolophus melanotoma Costa reduced B. tabaci on the eggplant crops in greenhouse [229]. The antagonistic properties of Encarsia Formosa Gahan, Eretmocerus eremicus Rose and Zolnerowich, and E. mundus Mercet have been well studied [228] but among these, Encarsia Formosa Gahan is the most common parasitoid deployed on leafy vegetables for WFM under contained conditions.…”

Whitefly (Bemisia tabaci) Management (WFM) Strategies for Sustainable Agriculture: A Review

et al. 2022

View full text Add to dashboard Cite

The whitefly (Bemisia tabaci Gennadius) is a notorious devastating sap-sucking insect pest that causes substantial crop damage and yield losses due to direct feeding by both nymphs and adults and also through transmission of viruses and diseases. Although the foliar application of synthetic pesticides is crucial for efficient control of B. tabaci, it has adverse effects such as environmental pollution, resistance and resurgence of the pest, toxicity to pollinators, and crop yield penalty. Thus, a suitable, safe, and robust strategy for the control of whiteflies in the agricultural field is needed. The reports on whitefly-resistant transgenic plants are scanty, non-reproducible, and/or need secondary trials and clearance from the Genetic Engineering Appraisal Committee (GEAC), the Ministry of Environment and Forests (MoEF), and the Environmental Protection Agency (EPA). The present review encompasses explicit information compiled from 364 articles on the traditional, mechanical, biological, biotechnological, and chemical strategies for whitefly management (WFM), IPM strategy, and future prospects of WFM for food and agriculture security.
