“…It is believed that biological control through habitat management may lead to a more sustainable pest control approach [ 46 ]. The fact that most smallholder farmers do not use insecticides in maize production should be considered as an advantage for the implementation of IPM programs based on biological control of FAW.…”

The alien invasive insect pest Spodoptera frugiperda Smith (Lepidoptera: Noctuidae), commonly referred to as fall armyworm (FAW), is causing significant losses to maize production in Africa since its detection in 2016. As an emergency response, governments in several countries distributed and/or promoted massive use of synthetic insecticides among smallholder farmers to fight FAW. The inappropriate use of synthetic insecticides by non-trained and ill-equipped farmers raises environmental and health concerns. This study aimed to assess the occurrence of native parasitoids of FAW, their parasitism rates, and relative abundance in the central province of Manica, Mozambique. A field collection of FAW egg masses and larvae was conducted from May to August 2019 (dry season of the 2018/2019 cropping season) and in December 2019 and January 2020 (rainy season of 2019/2020 cropping season). A total of 101 egg masses and 1444 larvae of FAW were collected from infested fields. Five larval parasitoids were recorded, but no egg parasitism was observed. Coccygidium luteum Brullé (Hymenoptera: Braconidae) and Drino quadrizonula Thomson (Diptera: Tachinidae) were the primary parasitoids. Maximum parasitism of 23.68% and 8.86% and relative abundance of 100 and 96.3 were recorded for C. luteum and D. quadrizonula, respectively. Total parasitism by different parasitoid species was at 9.49%. Cultural practices favoring the action of these parasitoids should be advocated.

“…Biological controls constitute effective methods including natural enemies of insect pests as control agents such as parasitoids (e.g., Diapriidae for flies) [21], predators (e.g., Ophionea nigrofasciata ) [22], genetic sterilisation [23], pathogens (viral infections) [24,25], or the exploitation of competitor relationships (e.g. a competition for preying between the protist Didinium and Paramecium ) [26].…”

World-wide rice consummation constantly grows constantly with non-proportional yield as large amounts of rice are lost due to pest infestations. Cultural methods were widely applied at an early stage of agricultural pest management but then replaced over time through insecticides. To describe a rice-pest system and to control the corresponding pests applying cultural methods and/or insecticides, statistical analyses have been used, and also other mathematical models using an Integrated Pest Management (IPM) strategy considering long time period and more parametric values. Considering the limitations of IPM, we have developed a mathematical model for a rice-pest system found in agricultural management. The mathematical model consists of two non-linear differential equations (NDEs) to illustrate the interrelation of rice and its corresponding agricultural pests. This model is extended to become an optimal control problem (minimization problem), considering both, cultural methods and pesticides, to minimize the density of agricultural pests and to increase the production of rice, reducing gross annual losses. Pesticides have been applied only in emergencies to reduce environmental pollution and damage to nearby ecosystems such as aquatic ecosystems, and a decision model has also been developed to mitigate potential risks. To compare the effectiveness of the considered controls, the ratio of annual production of rice is studied for both controls and without control. This study contributes to building a relationship between NDEs and agricultural management as well as connecting mathematically rice-pest relationships to global food security.

“…; Grzywacz et al, 2014). When it is not possible to avoid pollution from GBHs, remediation techniques need to be employed, including the use of residual by products from industry and agriculture for the production of chemical adsorbents (Jiang et al 2018), bioremediation (Masotti et al 2021), phytoremediation (Priyadharshini et al 2021), and biotechnologies for pesticide removal (Espinoza-Montero et al 2020).To mitigate the damage caused by pest insects like Gryllus in various crops, additional protective measures can be implemented, such as the use of biological control methods involving natural predators, parasitoids, nematodes, bacteria, fungi, and viruses(Kumari et al 2022), monitoring of pest populations followed by predictions of damage intensity (Speight 2016), management of pest insect habitats(Akter et al 2019), and physical control methods(Thakur et al 2021). The unregulated application of GBH combined with intensi ed environmental impacts reduces the longevity of non-target insects and generates responses that are still poorly understood, which can cause chronic detrimental effects to the environment(Druille et al 2016;Gill et al 2017;Van Bruggen et al 2018).…”

Brazil is an important global agricultural producer and to increase production the country has extensively used glyphosate-based herbicides (GBH), surpassing consumption and sales records. Consequently, concerns have arisen regarding the potential impact of GBH on ecosystems and non-target organisms. Thus, the effects of GBH exposure were evaluated throughout the cricket Gryllus (Gryllus) assimilis ontogeny, with five developmental stages. Each period contained 3 control and 3 treated boxes, with 15 crickets each, resulting in 90 insects at a time. The control groups received water, while the treated ones were continuously exposed to GBH (0.864 mg.GBH.L-1), with the solutions changed every 48 hours. After each exposure time the crickets’ group were euthanized to assess the activity of antioxidant enzymes (GST, GR, GPx, and CAT), cholinergic enzymes (ChE), and lipid peroxidation (LPO). The results revealed changes in the systems throughout different developmental phases. Specifically, CAT activity exhibited a significant increase during the nymphal phase, associated with the dismutation of hydrogen peroxide. The GST increased GBH, indicating its role in cellular detoxification, particularly during adulthood. In the senescence stage there was a considerable rise in ChE enzymes, suggesting their involvement in both, choline esters breakdown and potential pesticide detoxification. The action of these enzymes to effectively control lipid peroxidation shows the adaptability of this species to environmental contamination. These findings underscore the long-term effects of agrochemical pollution and emphasize the importance of sustainable practices, effective regulations, and alternative weed control methods.
