“…However, they may still present difficulties in targeting and selectivity when sprayed. Furthermore, bioinsecticides have storage difficulties [59], and their efficacy and persistence are strongly conditioned by the substrate and the environmental conditions of application [60]. For example, the survival of Bb is reduced to a few days if sprayed on synthetic surfaces as polypropylene or used in unsuitable operating conditions such as exposure to heat, UV radiation, and substrate drying, thus affecting the persistence of the insecticide product [61].…”

Background Pest management has been facing the spread of invasive species, insecticide resistance phenomena, and concern for the impact of chemical pesticides on human health and the environment. It has tried to deal with them by developing technically efficient and economically sustainable solutions to complement/replace/improve traditional control methods. The renewal has been mainly directed towards less toxic pesticides or enhancing the precision of their delivery to reduce the volume employed and side effects through lure-and-kill approaches based on semiochemicals attractants. However, one of the main pest management problems is that efficacy depends on the effectiveness of the attractant system, limiting its successful employment to semiochemical stimuli-responsive insects. Biomaterial-based and bioinspired/biomimetic solutions that already guide other disciplines (e.g., medical sciences) in developing precision approaches could be a helpful tool to create attractive new strategies to liberate precision pest management from the need for semiochemical stimuli, simplify their integration with bioinsecticides, and foster the use of still underemployed solutions. Approach proposed We propose an innovative approach, called “biomimetic lure-and-kill”. It exploits biomimetic principles and biocompatible/biodegradable biopolymers (e.g., natural hydrogels) to develop new substrates that selectively attract insects by reproducing specific natural environmental conditions (biomimetic lure) and kill them by hosting and delivering a natural biopesticide or through mechanical action. Biomimetic lure-and-kill-designed substrates point to provide a new attractive system to develop/improve and make more cost-competitive new and conventional devices (e.g. traps). A first example application is proposed using the tiger mosquito Aedes albopictus as a model. Conclusions Biomaterials, particularly in the hydrogel form, can be a useful tool for developing the biomimetic lure-and-kill approach because they can satisfy multiple needs simultaneously (e.g., biomimetic lure, mechanical lethality, biocompatibility, and bioinsecticide growth). Such an approach might be cost-competitive, and with the potential for applicability to several pest species. Moreover, it is already technically feasible, since all the technologies necessary to design and configure materials with specific characteristics are already available on the market.

“…Biopesticides are derived from natural materials and organisms that can control pests and diseases [ 3 ]. Among them, entomopathogenic fungi (EPF), naturally occurring soil microorganisms, have gained popularity as a promising alternative to synthetic pesticides due to their specificity toward target insects (they act mainly by contact with the insect), low toxicity to non-target organisms and environmental and health safety [ 4 ].…”

Biopolymer-based formulations show great promise in enhancing the effectiveness of entomopathogenic fungi as bioinsecticides. Chitosan and starch, among other biopolymers, have been utilized to improve spore delivery, persistence, and adherence to target insects. These formulations offer advantages such as target specificity, eco-friendliness, and sustainability. However, challenges related to production costs, stability, and shelf life need to be addressed. Recently, biomimetic lure and kill approaches based on biopolymers offer cost-effective solutions by leveraging natural attractants. Further research is needed to optimize these formulations and overcome challenges. Biopolymer-based formulations have the potential to revolutionize pest control practices, providing environmentally friendly and sustainable solutions for agriculture.

“…The huge spread of agricultural pests poses a hazard to the food sector and human health. Therefore, there is a growing trend to control these pests using biological agents ( Melo & Swarowsky, 2022 ). Different chemical-based fungicides and insecticides are used in the form of sprays in the soil applications for the controlling the attack of insects.…”

The peachfruit fly, Bactrocera zonata (Saunders) is a polyphagous pest in nature, belonging to order, Diptera and their respective family is Tephritidae. It mostly feeds on different crops, vegetables and fruits. Different traditional chemical insecticides have been used to control this notorious pest. Excessive consumption of pesticides has become a major threat to the fresh fruits trade since many importing countries refused to accept the shipments due to public health and environmental concerns. There is a growing trend to control these pests using the most effective biological control methods and other preventive measures have been adopted for reducing their attacks. Fungal agents have been used as biological agents to manage the attack of different insects pest through biological means. The present study was conducted to assess the virulence of three entomopathogenic fungi, Metarhizium anisopliae, Beauveria bassiana and Verticillium lecanii, against Bactrocera zonata stages under different laboratory conditions. The results showed that B. bassiana and M. anisopliae were more effective in pathogenicity and potentially kill at all stages of B. zonata as compared to V. lecanii. The highest mortality rate for the third larval instar and the pupal stage were recorded after exposure to the 1 × 1010 conidia/ml concentrations, B. bassiana, with 68.67% and 89.67%, respectively. Adult B. zonata flies were the most susceptible to all entomopathogenic fungi. However, M. anisopliae was more virulent against B. zonata adult flies than B. bassiana and V. lecanii at 1 × 1010 conidial concentration. Therefore, the entomopathogenic fungi B. bassiana and M. anisopliae can be used as an cost effective bio-insecticide in the integrated pest management programs to control B. zonata. This study will be helpful to overcome this pest through biological control means.
