“…Ricin is dubbed one of the most naturally poisonous and acts through the inactivation of a ribosome in the affected organisms [63], which affects protein synthesis. Azadirachtin, a tetranortriterpenoid, is a chemical compound derived from neem and is a tremendous antifeedant and insect growth disruptor with negligible residual effect and minimal toxicity to biocontrol agents, predators, and parasitoids [46] [64].…”

“…The natural active ingredient in pyrethrum extracts is pyrethrin. Pyrethrins are six related insecticidal esters occurring naturally in the crude material of Chrysanthemum flowers, formed by the combination of the acids, chrysanthemic and pyrethric acid, and the alcohols pyrethrolone, cinerolone, and jasmolone [55] [64]. As reviewed by [55], the natural pyrethrin compound has a reduced photostability and is more biodegradable than the synthetic pyrethroids.…”

“…Pyrethrins exert their toxic effects by disrupting voltage-gated SDVC and PVDC, which negates the Na + and K + ion exchange process in insect nerve fibers, which knocks down normal transmission of nerve impulses [55] [64], causing paralysis. However, despite their rapid toxic action, many insects can digest pyrethrins quickly and, after a period of paralysis, recover instead of dying [64]. To increase their killing power, a synergist, piperonyl butoxide (PBO), can be added to natural pyrethrins [65], which prevents insects from metabolizing pyrethrins and recovering from poisoning.…”

The pulse cowpea [Vigna unguiculata (L.) Walp] holds a significant agricultural position in Uganda, ranking fourth among legume crops, following common beans, groundnuts, and soybeans. Known for its versatility, cowpeas are consumable at various developmental stages, from early seedling to maturity. However, the crop faces persistent pest challenges at each stage, leading to substantial yield losses. In Uganda, chemical insecticides are the primary pest control means, but their increased and excessive use raises environmental, health, and economic concerns. This has prompted a quest for alternative and sustainable solutions, prompting an exploration of botanical insecticides. This study, conducted at Makerere University Agricultural Research Institute (MUARIK), aimed to evaluate the effectiveness of three selected botanical insecticides versus four established chemical insecticides for managing cowpea insect pests under field conditions. The treatments included: Carbofuran, Cypermethrin 10% EC, Dimethoate, Pestwin, Pyrethrum ewc+, Pyrethrum 5ew, Profenofos 40% + Cypermethrin 4% EC mix, and Untreated, arranged in a randomized complete block design with three replications. The significant pests studied were aphids, thrips, pod-sucking bugs, and legume pod borer. Results indicated substantial impacts of the treatments on pest infestation, with Profenofos 40% + Cypermethrin 4% EC being the most effective against most pests. The plant parameter, plant height, was significantly affected by treatments in 2016B, while the number of pods was impacted in 2017A. Pestwin, a botanical insecticide blend (containing Azadirachtin indica, Pongamia pinnata, and Ricinus communis extracts) demonstrated superior efficacy against cowpea aphids. Moreover, it positively influenced plant height, number of pods, and pod biomass, surpassing many chemical

“…In the field of agronomy, these compounds constitute economical, non-toxic and, consequently, environmentally friendly pesticides for sustainable agriculture. They represent a green alternative to synthetic pesticides, which are hazardous to living beings and the environment [ 132 , 133 , 134 ]. Among green chemicals, zerumbone, the main component of ginger plants, has demonstrated phytotoxic, antimicrobial, and insecticidal effects.…”

Zerumbone is a multifunctional compound with antimicrobial, antitumor, hyperalgesic, antioxidant and anti-inflammatory applications, and constitutes a point molecule for the future synthesis of derivatives with improved efficiency. This monocyclic sesquiterpenoid is found in high content in wild ginger (Zingiber zerumbet Smith), a perennial herb with economic importance as an ornamental as well as a medicinal plant. The presence of zerumbone is a distinctive feature that allows identification and differentiation from other species, not only in Zingiber, but also in Curcuma, Alpinia, Boesenbergia, Ethlingera and Ammomum spp., as well as related families (Costaceaee). To successfully use zerumbone in areas such as medicine, food and agriculture, further research on improving its low solubility and bioavailability, as well as its preservation, is a major current priority. In addition, despite its promising pharmacological activities, preclinical and clinical studies are required to demonstrate and evaluate the in vivo efficacy of zerumbone.

“…Uno de estos compuestos naturales es el compuesto rotenona, de acción neurotóxica y de parálisis (Soto, 2013). De acuerdo con varios autores, la rotenona, posee propiedades biocidas (Subhash et al, 2022) e ixodicidas (Soto, 2013), por lo que es considerado una alternativa factible como bioinsecticda para el control de V. destructor, como lo han expuesto, Gregorc y Poklukar, (2003), Eguaras et al (2005) y Gregorc y Škerl (2007) al determinar el efecto acaricida sobre V. destructor con una mortalidad mayor al 70 %. Además, una baja toxicidad para A. mellifera, durante la aplicación y exposición a la rotenona (Eguaras et al, 2005).…”

Background: The main problem of beekeeping activity in Mexico is parasitosis by Varroa destructor, due to its wide distribution and the damage it produces in apiaries, causing mortality in bees and reduction in honey production levels. Therefore, it is essential to develop sanitary control strategies for varroasis, avoiding causing the presence of resistant vectors, harmful damage to bees, beekeepers, consumers or any type of surrounding contamination or in the main products of the hive. Objective: To evaluate the acaricidal activity of Pachyrhizus erosus (jicama) on the mite V. destructor in colonies of Apis mellifera. Methodology: For the obtain of the extract from mature jicama seed, the hot maceration/extraction method (bain-marie) was used, using ethanol 95° G.L (95%) as solvent. A completely random design was developed. randomized with two dilutions of P. erosus (5 and 10%), a negative control (distilled water) and a positive control (Cumavar®), with three repetitions, respectively. The treatments were applied by means of two plastic strips (between frames 6 and 10) impregnated with the corresponding concentrations. Results: The highest count of accumulated mites was presented in the positive control with 386 (128.67±22.74). During the sampling, an initial infestation rate of 4.54±1.64 was determined. On the other hand, the final infestation rate was 2.66±2.69. The effectiveness of the treatments was statistically significant among themselves. The 5 and 10% dilutions of the P. erosus seed extract presented an acaricidal effect with percentages greater than 45% (48.99±15.1 and 59.44±13.57% of effectiveness, respectively). Likewise, the positive control presented the highest percentage, 84.41±14.47. Implications: Trials should be developed with a greater number of experimental units and records with a longer post-application time, with the aim of evaluating their residual and harmful effect that these may have on non-target individuals such as bees. Conclusion: Exploratory data on the acaricidal effect of P. erosus seed on V. destructor and its application as a means of controlling varroa infestation were presented, as a feasible alternative for the development of strategies for the sanitary control of varroa.
