“…Novaluron had the highest sterility value (68.9%) for S. littoralis 64 . The ethanolic extracts of S. terebinthifolius negatively affected all the evaluated biological parameters of P. xylostella, increasing the duration of the larval stage, which led to reduced pupal mass and oviposition period 76 . Treatment with S. terebinthifolius extract resulted in the lowest pupal mass and a greatest prolongation of the larval stage compared with other treatments 73 .…”

Finding innovative eco-friendly agents for pest control may be aided by investigating the plant-derived extracts’ properties on economic pests. Therefore, the insecticidal, behavioral, biological and biochemical effects of Magnolia grandiflora (Magnoliaceae) leaf water and methanol extracts, Schinus terebinthifolius (Anacardiaceae) wood methanol extract, and Salix babylonica (Salicaceae) leaf methanol extract in comparison with a reference insecticide novaluron against S. littoralis were evaluated. The extracts were analyzed by High-Performance Liquid Chromatography (HPLC). The most abundant phenolic compounds were 4-hydroxybenzoic acid (7.16 mg/mL) and ferulic acid (6.34 mg/mL) in M. grandiflora leaf water extract; catechol (13.05 mg/mL), ferulic acid (11.87 mg/mL), and chlorogenic acid (10.33 mg/mL) in M. grandiflora leaf methanol extract; ferulic acid (14.81 mg/mL), caffeic acid (5.61 mg/mL), and gallic acid (5.07 mg/mL) In the S. terebinthifolius extract; cinnamic acid (11.36 mg/mL), and protocatechuic acid (10.33 mg/mL) In the methanol extract from S. babylonica extract. S. terebinthifolius extract had a highly toxic effect against second larvae after 96 h and eggs with LC50 values of 0.89 and 0.94 mg/L, respectively. Despite M. grandiflora extracts didn’t show any toxicity against S. littoralis stages, they had an attractant effect on fourth- and second larvae, with feeding deterrence values of − 2.7% and − 6.7%, respectively, at 10 mg/L. S. terebinthifolius extract significantly reduced the percentage of pupation, adult emergence, hatchability, and fecundity, with values of 60.2%, 56.7%, 35.3%, and 105.4 eggs/female, respectively. Novaluron and S. terebinthifolius extract drastically inhibited the activities of α-amylase and total proteases to 1.16 and 0.52, and 1.47 and 0.65 ΔOD/mg protein/min, respectively. In the semi-field experiment, the residual toxicity of tested extracts on S. littoralis gradually decreased over time compared to novaluron. These findings indicate that extract from S. terebinthifolius is a promising insecticidal agent against S. littoralis.

“…Vários estudos já foram realizados promovendo a investigação de propriedades bioativas de várias famílias vegetais Annonaceae, Meliaceae, Asteraceae, Rubiaceae, Rutaceae, Euphorbiaceae, Solanaceae, Onagraceae, Anacardiaceae e Sapindaceae (JACOBSON, 1989;AMOABENG et al, 2013;KRINSKI et al, 2014;PERES et al, 2017;COUTO et al, 2020;FERREIRA et al, 2020).

A traça-das-crucíferas, Plutella xylostella (Linnaeus) (Lepidoptera: Plutellidae), é um inseto comumente encontrado na cultura das brássicas, sendo o principal responsável pelos prejuízos econômicos nesta cultura. O manejo químico utilizado para o seu controle, além de elevar os custos econômicos, não são ambientalmente saudáveis. Como alternativa, os inseticidas botânicos podem ser uma ferramenta sustentável para o meio ambiente e suas aplicações tópicas podem causar alterações na biologia de P. xylostella, contribuindo para o seu controle. Diante disso, verificamos a toxicidade dos extratos aquosos de Serjania erecta Radlk (Sapindaceae) e Serjania marginata Casar (Sapindaceae), nas concentrações 5% e 10%, aplicados topicamente sobre ovos, larvas e pupas de P. xylostella. Para isso, foi realizada a imersão dos ovos de P. xylostella nos respectivos tratamentos contendo extratos aquosos de S. erecta e S. marginata, nas concentrações 5% e 10%. Além disso, foram aplicados 20 μl destes tratamentos em larvas e pupas de P. xylostella. Foram avaliados a viabilidade de ovos (%), a sobrevivência larval (%) e a sobrevivência pupal (%). Observamos que os tratamentos à base de S. erecta e S. marginata alteraram todas as características estudadas, sendo que os extratos aquosos contendo S. marginata foram mais eficazes na redução da sobrevivência larval e pupal de P. xylostella. Também verificamos que a concentração 10% intensificou a mortalidade larval. Portanto, concluímos que os extratos aquosos de ambas as espécies apresentaram potencial para serem utilizadas como bioinseticidas tópicos, sendo tóxicos para ovos, larvas e pupas de P. xylostella.

“…In this regard, extracts and/or essential oils from several plants proved to exert insecticidal activity against vegetables and stored product pests and have been proposed for practical application [ 4 , 5 , 6 , 7 ]. Among the plethora of plant species investigated [ 8 , 9 , 10 , 11 , 12 ], hop, Humulus lupulus (L.), is receiving increasing interest for possible re-utilization after commercial use (e.g., beer production) and for its bioactivity against bacteria, yeast, fungi, and insects [ 13 , 14 , 15 , 16 ]. Besides spent hop, wild hop also showed remarkable activity against pests, such as Colorado potato beetles ( Leptinotarsa decemlineata Say) (Coleoptera: Chrysomelidae) [ 17 , 18 , 19 ], as well as noxious insects and other invasive species [ 14 , 20 ].…”

The use of bioinsecticides, rather than synthetic compounds, appears a goal to be pursued in pest control, especially for species such as Sitophilus granarius (L.) which attack stored products. Since Humulus lupulus (L.) is a remarkable source of bioactive compounds, this study investigated the bioactivity of hop flower extracts against S. granarius adults by evaluating toxic (contact, inhalation, and ingestion), repellent, antifeedant, and nutritional effects as well as their anticholinesterase activity and olfactory sensitivity. Hop extracts were obtained by soaking dried and ground hop cones in solvents of decreasing polarity: methanol, acetone, and n-hexane. Dried crude extracts were resuspended in each solvent, and used in topical application, ingestion, and fumigation toxicity assays, as well as in contact and short-range repellency tests, in vitro anticholinesterase activity evaluation, and electroantennographic tests. No inhalation toxicity for the extracts was found. On the contrary, all extracts showed adult contact toxicity 24 h after treatment (LD50/LD90 16.17/33.20, 25.77/42.64, and 31.07/49.48 µg/adult for acetone, n-hexane, and methanol extracts, respectively); negligible variations for these values at 48 h were found. The anticholinesterase activity shown by all extracts suggested that the inhibition of this enzyme was one of the mechanisms of action. Interestingly, flour disk bioassays revealed a significant ingestion toxicity for the acetone extract and a lower toxicity for the other two extracts. Moreover, all extracts affected insect nutritional parameters, at the highest dose checked. Filter paper and two-choice pitfall bioassays showed repellent activity and a strong reduction of insect orientation to a highly attractive food odor source, with minor differences among extracts, respectively. Finally, the presence of volatile compounds in the different extracts that are perceived by insect antennae was confirmed by electroantennography. All these findings strongly suggest a possible use of hop cone extracts against S. granarius, thus further confirming this plant as an interesting species for pest control.
