“…As discussed by other researchers, successful biocontrol of aphids in greenhouse crops can be a challenge (Boivin et al, 2012 ; Glastuinbouw Nederland, 2020 ; Messelink et al, 2014 ; Sanchez et al, 2007 ) and there are many management‐related and biological factors that might explain the variable success of parasitoid‐based aphid biocontrol. Examples of management‐related factors are the quantity and frequency of parasitoid release (Hopper & Roush, 1993 ), provision of shelter, food and hosts to promote preventative establishment of natural enemies in the crop (standing army; Messelink et al, 2014 ; Pijnakker et al, 2020 ), and the usage of pesticides with untargeted side effects on biocontrol agents (Alfaro‐Tapia et al, 2021 ; Cloyd & Bethke, 2011 ). Altogether, the management of aphid pest control is highly affected by the type of farming management practised in a greenhouse, whether it be organic or conventional.…”

Biological control (biocontrol) of crop pests is a sustainable alternative to the use of biodiversity and organismal health‐harming chemical pesticides. Aphids can be biologically controlled with parasitoid wasps; however, variable results of parasitoid‐based aphid biocontrol in greenhouses are reported. Aphids may display genetically encoded (endogenous) defences that increase aphid resistance against parasitoids as under high parasitoid pressure there will be selection for parasitoid‐resistant aphids, potentially affecting the success of parasitoid‐based aphid biocontrol in greenhouses. Additionally, aphids may carry secondary bacterial endosymbionts that protect them against parasitoids. We studied whether there is variation in either of these heritable elements in aphids in greenhouses of sweet pepper, an agro‐economically important crop in the Netherlands that is prone to aphid pests and where pest management heavily relies on biocontrol. We sampled aphid populations in organic (biocontrol only) and conventional (biocontrol and pesticides) sweet pepper greenhouses in the Netherlands during the 2019 crop growth season. We assessed the aphid microbiome through both diagnostic PCR and 16S rRNA sequencing and did not detect any secondary endosymbionts in the two most encountered aphid species, Myzus persicae and Aulacorthum solani. We also compared multiple aphid lines collected from different greenhouses for variation in levels of endogenous‐based resistance against the parasitoids commonly used as biocontrol agents. We found no differences in the levels of endogenous‐based resistance between different aphid lines. This study does not support the hypothesis that protective endosymbionts or the presence of endogenous resistant aphid lines affects the success of parasitoid‐based biocontrol of aphids in Dutch greenhouses. Future investigations will need to address what is causing the variable successes of aphid biocontrol and what (biological and management‐related) lessons can be learned for aphid control in other crops, and biocontrol in general.

“…They are natural insecticides derived from the flowers of certain species of chrysanthemum, Dalmatian pyrethrum (Tanacetum cinerariifolium) [198]. Pyrethrins have certain advantages as IPM tools such as their low toxicity to mammals, birds, and beneficial insects, such as predators and pollinators [198][199][200][201][202][203], and their short environmental persistence as they break down quickly in sunlight and air, leaving no residues [203,204]. However, pyrethrins also have some limitations and challenges such as reductions in longevity and fecundity in certain parasitoids [205], a repellent effect in some insects [206], and the emergence of resistance [207][208][209][210].…”

Mediterranean olive cultivation faces challenges in the global environmental change context. Pests and diseases caused by arthropods such as Bactrocera oleae, Prays oleae, and certain vectors of Xylella fastidiosa are expected to increase and spread in part due to this global scenario. The control of these arthropods has relied on synthetic pesticides, the misuse of which has led to pest population resistance and concerns about their negative impacts on biodiversity and global health. Integrated pest management (IPM) methods have emerged through the careful consideration of all available control techniques and the subsequent integration of appropriate measures that discourage the development of pest populations. This paper reviews the IPM guidelines for olive cultivation, prioritizing the use of biological control methods, and the integration of genetics and biotechnology, which bring precision, efficacy, and safety. It evidences the importance of genetic analysis in pest populations, pesticide resistance and in the contributions of predators to pest control. Advances in formulations and delivery systems for pesticides such as Bacillus thuringiensis, plant-incorporated protectants, improved SIT techniques, and the specific efficacy of biologicals pesticides are covered. Finally, this paper explores promising tools such as RNAi and gene drive while recognizing the ethical, environmental, and regulatory challenges associated with their use. Shortly, these innovations have the potential to reduce the environmental impacts of pests while ensuring the long-term viability of the olive industry.

“…Till now, the control of this insect and other agricultural pests still relies heavily on synthetic insecticides to protect plants and post-harvest crops [5]. The use of synthetic insecticides can cause pest control failure due to undesirable side effects on plants and rapid development of insecticide resistance in agroecosystems [6]. Therefore, there is an urgent need for discoveries regarding new natural pesticides to prevent damage to crops and the environment [7].…”

In view of the environmental and health problems caused by industrial pesticides and their negative impact on various aspects of life, the attention of researchers and specialists has turned to natural alternatives that contain effective compounds in control insects. The present study tested the effect of four natural plant extracts (Nerium oleander, Melia azedarach, Ocimum basilicum and Mentha arvensis) in mortality the third-age larvae of the tobacco leaf-cutworm (Spodoptera litura). The results showed a variation in mortality rates depending on the type of extract, concentration, and date of taking the reading. The extracts of the M. azedarach fruits were significantly superior to the leaves of the M. azedarach and the leaves of N. oleander, where the averages reached 47.22, 37.20, and 33.83%, respectively, while the extracts of M. arvensis and O. basilicum showed relatively low mortality rates. The mortality rates also increased over time, reaching 53.31% at 96 hours after treatment, while it was 24.39% at 48 hours, which indicates the Antifeeding behavior of these natural substances, which is similar to the action of compounds such as azdrachtin. It can be said that these natural pesticides can be good tools in pest management programs.
