“…Lanosterol acts on the insect endocrine system and alters insect feeding habit leading to antibiosis (Bowers, Ohta, Cleere, & Marsella, 1976). In addition, lanosterol was reported to modify the synthesis of JH and the targeted cells by superseding for cholesterol synthesis (Duprat et al, 2017), leading to JH crisis for insect survival. On the other hand, lanosterol metabolism was found to be associated with strong resistance to fusarium species (Koch et al, 2013) in legumes.…”

A narrow genetic base in cultivated pigeonpea (Cajanus cajan (L.) Millsp.) limits the host plant resistance (HPR) to the devastating pest Helicoverpa armigera (Hübner). Earlier research on pod borer resistance in wild Cajanus relatives has mainly explored the tertiary genepool, making breeding for resistance difficult because of linkage drag. Previous investigations on a wide range of Australian native germplasm from the secondary and tertiary gene pools revealed resistance in the secondary gene pool, associated with total phenolic content (TPC). This study reports the application of the extreme phenotype genome‐wide association (XP‐GWAS) to associate single nucleotide polymorphisms (SNPs) with resistance traits. Mapping of 19 accessions, including 12 wild accessions to a reference pigeonpea genome have identified a total of 16,489 and 16,227 nonsynonymous SNPs for the resistance and TPC traits, respectively. These SNPs were subjected to functional analysis, and KEGG pathway analysis revealed the presence of candidate genes coding for the crucial enzymes in five defence‐related pathways that could be contributing to resistance. These pathways involve ‘Jasmonic acid synthesis’ (palmitoyl‐CoA hydrolase, phospholipase A1 and phospholipase A2), ‘insect hormone biosynthesis’ (aldehyde dehydrogenase) ‘Steroid biosynthesis’ (squalene monooxygenase, farnesyl transferase and lanosterol synthase), ‘Cutin, suberine and wax synthesis’ (O‐acyltransferase) and ‘Brassinosteroid biosynthesis’ (Det2). Analysis of SNPs associated with the TPC trait led to the identification of a divergent pathway of ‘secondary metabolite synthesis’ (flavonoid 3′ hydroxylase, l‐rhamnosyltransferase) in wild Cajanus species consistent with a high concentration of isoorientin and the possible presence of its derivative maysin; a strong insecticidal compound in leaves.

“…O inseto modelo O. fasciatus apresentou sensibilidade à extratos hexânicos de Clusia fluminensis (Duprat et al, 2017). A substância isolada lanosterol mostrou resultados satisfatórios quanto a mortalidade de O. fasciatus, além disso, em relação ao desenvolvimento das ninfas em adultos, ocorreram atrasos significativos nos insetos tratados com este triterpeno (Duprat et al, 2017).…”

Atividade inseticida da neolignana Burchelina sobre Oncopeltus fasciatus

Insetos praga são modelos de estudo na busca de métodos alternativos de controle que não agridam o homem e o meio ambiente, devido aos efeitos nocivos às plantações de grãos causando grandes impactos econômicos. O estudo buscou avaliar o potencial inseticida e ovicida da neolignana Burchelina sobre Oncopeltus fasciatus. Os bioensaios foram conduzidos no Laboratório de Insetos Vetores, da Universidade de Vassouras sobre ninfas de 5º estádio, em triplicatas por grupo e com três repetições. Nas ninfas, a substância foi utilizada por tratamento tópico nas concentrações de 1, 10, 50, 100 e 200 µg/mL. Após o tratamento, as ninfas foram mantidas em temperatura ambiente, dieta habitual (água e semente de girassol) e observadas durante 20 dias. Os bioensaios sobre a massa de ovos foi realizada por aplicação tópica na concentração de 82 µg/mL (DL50). Foram utilizados 20 mg de ovos/20 µL da substância, em triplicata. O tratamento tópico com Burchelina resultou na mortalidade de ninfas de 5º estádio em 73% (200µg) e de 100% de toxicidade (82µg) sobre os ovos de O. fasciatus. Estes resultados demonstraram o potencial inseticida da Burchelina e sua importância no controle do Hemiptera Lygaidae.

“…Thus, insect growth regulators (IGRs) as EOs that are environmentally friendly has been integrated into modern vector and crop control programs since they are ecologically safer, degradable, and target specific (Isman 2005;Mello et al 2007;Fernandes et al 2013;Gonzalez et al 2014;Fernandes et al 2014, Duprat et al 2017, Tietbohl et al 2019, Rosado et al 2019). In the case of EOs, some, or their chemical components, are already in use as flavoring components in foods and beverages and are even exempt from pesticide registration.…”

Agricultural crops need protection from a variety of different insects popularly known as pests. Some of these pests are becoming increasingly resistant to conventional pesticides, so new control alternatives are needed. In this work, the effects of the essential oil of the plant Zanthoxylum caribaeum on the development of cotton stink bug Dysdercus peruvianus were analyzed. After analysis by chromatography and mass spectrometry, the essential oil of Z. caribaeum presented 54 substances, the main constituents being Sylvestrene, Muurola-4 (14), 5-trans-diene, Isodaucene and α-Pinene. These compounds significantly increased insect mortality and interrupted metamorphosis and molting, often in a dose-dependent manner. In addition, nymphs with deformed legs, wings and antennae were observed. According to the data, the components present in the essential oil of Z. caribeum appear to be promising candidates for the development of green insecticides for use in future integrated pest management (MIP) programs.
