Effect of Food Attractants and Insecticide Toxicity for the Control of Spodoptera frugiperda (Lepidoptera: Noctuidae) Adults

Abstract

An alternative for the population suppression of Spodoptera frugiperda is the use of toxic baits. The objective of this study was to evaluate the dietary preference and toxic effect of insecticides associated with the attractiveness of S. frugiperda adults as a pest management method. The following attractions were tested: 1) 5% sucrose solution, 2) 10% sugarcane syrup, 3) 10% honey, 4) 5% hydrolyzed protein, 5) Noctovi® 43sb, 6) Noctovi® OVI PLU 1-3, 7) Noctovi® OVI PHE/PAL 50-50 in the study with choice. Attractions: 1) sugarcane syrup 10%, 2) Noctovi® 43sb, 3) Noctovi® 43sb + sugarcane syrup 10%, 4) Noctovi® OVI PLU 1-3 in the study with no chance of choice. For the toxicity study, the food attraction associated with insecticides was used: methomyl 2%, lambda-cyhalothrin 1%, chlorpyriphos 2%, spinosad 1%, chlorantraniliprole 2% and chlorfenapyr 2%. The experimental design was the completely randomized design (CRD) with chance of choice, without chance of choice and toxicity. The following parameters were evaluated: number of insects that fed; time in minutes that remained in the attractive food and mortality. The molasses (10%) and Noctovi® 43sb food attractiveness were significantly more efficient in relation to feeding time and the highest number of landings was observed in the Noctovi® 43sb treatment, both in females and total adults. Methomyl, lambda-cyhalothrin and spinosad insecticides associated with food attractiveness are promising toxic baits for the management of S. frugiperda.

Toxic Bait as an Alternative Tool in the Management of Spodoptera frugiperda in Second Corn Crops

“…Research under laboratory conditions corroborated the adult FAW mortality caused by toxic bait using the active insecticides methomyl, lambda-cyhalothrin, and spinosad together with the Noctovi ® 43sb commercial food bait, with these mixtures causing 100% mortality in adults up to 5.29 h (Justiniano & Fernandes, 2020).…”

“…Semiochemicals can be an efficient alternative control method and tool for managing resistance development. Recently, studies conducted under controlled laboratory conditions have demonstrated the possibility of using commercial semiochemicals associated with chemical insecticide molecules for the management of FAW adults (Justiniano & Fernandes, 2020).…”

Large‐area field application confirms the effectiveness of toxicant‐infused bait for managing Helicoverpa armigera (Hübner) in maize fields

“…As an attractant, bio‐baits not only attract males, but also females. Compared with typical insecticides, bio‐baits are nonpolluting and less harmful to beneficial insects 19,25,30,33,51 . Our research results show that the combination of bio‐bait Bioattract®‐Heli and chemical insecticides can significantly reduce the population of H. armigera adults and offspring in the fields, and improve both the yield and the quality of maize.…”

“…As an important bio‐control technology, bio‐baits play a vital role in monitoring and controlling many important agricultural and forestry pests, including H. armigera , Spodoptera frugiperda J.E. Smith, Cydia pomonella L., Frankliniella occidentalis Pergande and Bactrocera dorsalis Hendel, among others 19,21–31 . The bio‐bait Magnet® is widely used in crops such as cotton and maize in Australia and the United States.…”

Volatiles Play an Important Role in the Attractiveness of Food for Trapping the Stored Grain Pests <em>Oryzaephilus surinamensis</em> L. (Coleoptera: <em>Silvanidae</em>)

“…Technology to attract and trap stored product insects using pheromones and other semiochemicals, as well as food attractants, was developed and has been emphasized widely in granaries as a suitable sampling and control method as part of the IPM system [3,5,17]. The use of attractants can lead to earlier detection of infestations, can accurately detect insect population levels, and can also help managers to take reasonable control measures and minimize pest damage before any chemical residues are deposited in the environment or in the food products [18,19]. Much progress has been made in controlling stored-product insects through food attractants and pheromones [15,20].…”
