TL;DR
The strategy for controlling Aculops lycopersici populations consisted of repeated treatments with biopesticides based on essential oils, and appears to be an effective measure for pest control and should be further implemented at the crop level.
Abstract
Bioinsecticides represent a modern generation of insecticides that utilize living organisms or their derivatives, such as transgenic plants, recombinant baculoviruses, toxic fusion proteins, and peptidomimetics. They represent promising ecological alternatives to conventional agrochemical pesticides. Over time, natural plant-derived compounds have demonstrated high efficacy in pest control, and currently, plant-based bioinsecticides are considered safer and less toxic options compared to synthetic substances. This article analyzes plant-derived compounds with insecticidal and repellent properties, highlighting both their mechanisms of action and their potential impact on disease transmission. This analysis contributes to a deeper understanding of plant-based bioinsecticides and highlights the potential for developing modern and effective strategies to combat pests, particularly the species Aculops lycopersici.
The strategy for controlling Aculops lycopersici populations consisted of repeated treatments with biopesticides based on essential oils. At the crop level, significant reductions in Aculops populations were observed, resulting in a significantly higher yield compared to the control plots, where treatments were carried out using only water. In conclusion, this biological approach appears to be an effective measure for pest control and should be further implemented at the crop level.
This study aims to evaluate the effectiveness of active compounds contained in several plant species as botanical pesticides to control mealybug pests (Pseudococcus lilacinus). Mealybugs are major agricultural pests that damage plants by sucking cell sap, leading to growth inhibition and yield loss. The excessive use of synthetic pesticides poses health and environmental risks and promotes pest resistance. Therefore, botanical alternatives are needed for safer and sustainable pest control. The research used plant extracts containing bioactive compounds such as alkaloids, flavonoids, saponins, tannins, and terpenoids, which act as contact poisons, antifeedants, and growth inhibitors. Laboratory tests were conducted to evaluate mortality rates of mealybugs under different extract concentrations. The results showed that certain plant extracts significantly increased mealybug mortality, indicating their potential as effective botanical pesticides. This finding supports the use of plant-based pesticides as an eco-friendly alternative to synthetic chemicals.

Brassica crops, including collard greens, are economically important vegetable crops cultivated worldwide. Among the major pests affecting these crops, the aphids Brevicoryne brassicae (Linnaeus) and Myzus persicae (Sulzer) (Hemiptera: Aphididae) are particularly relevant due to the direct and indirect damage they cause. Increasing consumer demand for sustainable agricultural practices and pesticide-free produce has intensified the search for environmentally friendly pest management alternatives. In this context, plant-derived insecticides have emerged as promising sources of bioactive compounds because of their biodegradability, selectivity, and generally low toxicity to non-target organisms and mammals. Likewise, agro-industrial residues such as avocado seeds have attracted attention as sustainable raw materials with potential bioactive and insecticidal properties. In the present study, biopolyols produced from avocado and neem seeds through a liquefaction process based on green chemistry and waste valorization principles were evaluated for their insecticidal activity against B. brassicae and M. persicae. A series of laboratory and field bioassays were conducted to assess toxicity and repellency effects on aphids. Among the tested formulations, the AAA avocado seed biopolyol (2:1/30 min) showed the highest insecticidal activity, possibly due to better preservation of bioactive compounds under the liquefaction conditions tested. Dose–response and lethal-dose (LD) analyses estimated an LD50 of 64 mg/mL and an LD90 of 429 mg/mL (p < 0.001) for the AAA biopolyol. In addition to its lethal effects, the LD90 concentration of the AAA biopolyol exhibited significant repellency against aphids and outperformed Azamax®applied at the recommended field rate. Field bioassays further demonstrated that both the AAA biopolyol at LD90 and Azamax® significantly reduced aphid abundance in collard greens of the ‘Manteiga’ cultivar under field conditions, compared to the control. Nonetheless, there was no difference in the efficacy of the AAA biopolyol and Azamax® in the field study. Altogether, these findings demonstrate the potential of seed-derived biopolyols as sustainable bioinsecticides for aphid management in Brassica crops, while also highlighting the value of agro-industrial waste as a source of novel bioactive compounds for integrated pest management programs.
The escalating reliance on synthetic chemical pesticides has caused significant environmental degradation, raised human health concerns, and accelerated the development of pesticide resistance. In response to these pressing challenges, botanical pesticides, which utilize natural plant-derived compounds, offer a viable, sustainable, and eco-friendly alternative for crop protection. Derived from sources such as neem, pyrethrum, and various essential oils, these natural secondary metabolites exhibit diverse modes of action against destructive pests, including neurotoxicity, antifeedant effects, and growth inhibition. This review paper comprehensively assesses the application of botanical pesticides, highlighting their numerous ecological benefits such as rapid biodegradability, lower environmental persistence, and minimal toxicity towards non-target organisms like pollinators. Despite these advantages, the widespread commercialization of botanical biopesticides faces several limitations, including variability in active compound concentration, slower knockdown rates compared to synthetics, and regulatory hurdles rooted in frameworks originally designed for conventional chemicals. To overcome these challenges, contemporary advancements in formulation technologies, such as microencapsulation and nanotechnology, are being explored to enhance their stability and field efficacy. Ultimately, the integration of botanical pesticides into modern Integrated Pest Management (IPM) strategies is essential for transitioning towards resilient, productive, and environmentally sustainable agricultural systems globally.

Sustainable farming faces an ongoing challenge from thrips, which are widespread agricultural pests that cause severe crop damage and spread harmful plant viruses. The overuse of chemical pesticides has backfired, leading to pest resistance, leaving toxic residues in the soil, and harming beneficial organisms, highlighting the need for eco-friendly alternatives for thrips management. Using biological controls offers a reliable path forward by capitalising on the natural interaction between predatory insects and plant-derived compounds. Beneficial organisms, such as Amblyseius swirskii (predatory mites) and minute pirate bugs, work alongside a variety of parasitoids to control thrips populations naturally. Furthermore, microscopic allies such as beneficial nematodes and specialised fungi (Beauveria bassiana and Metarhizium anisopliae) can be deployed to target pests at vulnerable points in their life cycles. Turning to botanical sprays, such as tobacco and neem-derived azadirachtin, also allows farmers to reduce dependency on synthetic chemical treatment. Combining these biological agents and botanical extracts into a unified Integrated Pest Management (IPM) model helps growers protect their crop yields, reduce chemical footprints, and build long-term agricultural resilience.

Synthetic pesticides have been extensively and often indiscriminately used for the management of insect and mite pests. Their prolonged and excessive use has led to insecticide resistance, environmental contamination, and adverse effects on non-target organisms and human health. These concerns have intensified the search for safer and sustainable botanical alternatives. Tagetes minuta (wild marigold) is a promising candidate, as it produces essential oils rich in bioactive compounds such as (Z)-β-ocimene and tagetone, which possess strong insecticidal, acaricidal, and repellent properties. The efficacy of T. minuta essential oil has been demonstrated against a wide range of pests, including stored-grain insects, field crop pests, and livestock ectoparasites. This review summarises the chemical composition, bioactivity, and pest management potential of T. minuta essential oil, highlighting its prospects as an eco-friendly alternative to conventional synthetic pesticides.
