“…With regard to secondary metabolites, Lima et al (2020) observed that the presence of tannins, saponins and phenolic compounds in the trunk bark extract of Genipa americana L. was able to inhibit the feeding of Tribolium castaneum adults, and its extract caused mortality of 73% of the insects and induced a decrease in the hatching rate (40-96%) of larvae.…”

Brazil is one of the largest grain producers in the world, but its productive potential is threatened by the presence of stored product pests that compromise quality and quantity. The use of synthetic insecticides and selective pressure make many of these pests increasingly resistant to control. Concern for health and the environment requires the development of less toxic and persistent products for the management of these undesirable organisms. The insecticide activity of aqueous extracts of 15 vegetal species was evaluated to control grain beetles, Sitophilus zeamais Motschulsky in maize stored. The adult insects came from the laboratory at Biological Institute of São Paulo. They were fed with sterilized grains of maize and kept in a room at 25±2°C and 70±% of relative humidity. The plants for the aqueous extracts were crushed in distilled water and the vegetal mass was filtered next. The liquid resulting from the filtering process was stored in plastic containers and frozen for later use. Two tests were conducted: impregnation of filter paper and treatment of grains. Ten insects were evaluated in each batch. Only the aqueous extract of Dahlia pinnata Cavanilles was satisfactory in controlling S. zeamais showing an efficiency of 10.00% in the contact test and an efficiency of 56% in the treated corn kernels.

“…As previously reported, plant extracts and an artificial diet with wheat bran present toxicity on stored food pests [31,32,46,47]. However, these studies were carried out in adult insects, and in our experiment, larvae were used, because in preliminary tests cannibalism was observed among adults of T. molitor.…”

“…The diet was prepared according to an adaptation of the methodology used by Lima et al [31]. Using wheat bran and distilled water, a solution was prepared at concentrations of 100 mg/g, 250 mg/g, and 500 m/g for each of the extracts, and stirred for 5 min.…”

Nematicidal and Insecticidal Activity of Proteases from Carica papaya and Ananas comosus

et al. 2023

Plant proteases are well known for their various industrial applications. Papain, present in papaya latex (Carica papaya) and pineapple bromelain (Ananas comosus), is undoubtedly the most studied and widely used vegetable protease in the food and pharmaceutical industry worldwide. However, its potential as a biopesticide has been little explored. The objective of this study was to evaluate the activity of proteases from Carica papaya latex and peel and crown of Ananas comosus fruits on agricultural pests. To evaluate proteolytic activity on nematodes, extracts, and approximately 50 juveniles of Panagrellus sp. were placed in microtubes. To evaluate the insecticidal effect, larvae and pupae of Tenebrio molitor L. were submerged in active and denatured extracts. Additionally, larvae of T. molitor were fed an artificial diet at doses of 0, 100, 250, and 500 mg/g of wheat bran. The weight and number of dead larvae were recorded, and feeding behavior was evaluated. The proteases of papaya latex and papain caused reduction (p < 0.05) on Panagrellus sp. The extracts showed a toxic effect (p < 0.05) against the larvae of T. molitor. Active papain resulted in the absence of wings in 53.3% of adults from the pupae, and no malformation caused by denatured papain was observed. No mortality was observed in larvae fed an artificial diet. However, there was a strong feed reduction, reduction in the relative rate of consumption, reduction in growth and feed conversion efficiency caused by papaya latex. The results of this study show that plant proteases have the potential for the development of sustainable alternatives for the control of arthropod pests and parasitic nematodes.
