Brown Planthopper Egg Parasitization in Rice Fields with Different Growth Ages

Jurnal Perlindungan Tanaman Indonesia, 2022
The brown planthopper, Nilaparvata lugens Stål. (Hemiptera: Delphacidae), is one of the most important pests attacking rice plants. One of the strategies to control this pest is by using natural enemies, including egg parasitoids.

Genistein induced by Frankliniella occidentalis feeding confers resistance to insect herbivores in peanut

New Plant Protection, EarlyView.
The Tianfu 22 (TF22) variety was identified as resistant to thrips based on field screening carried out over two consecutive years. Metabolomic profiling showed that thrip‐infested TF22 leaves exhibited differentially accumulated metabolites, particularly enriched in phenylpropanoid and secondary metabolite biosynthesis.

High migratory potential of fall armyworm in West Africa despite stable temperatures and widely available year‐round habitats

Insect Science, EarlyView.
Despite the minimal annual temperature variation and the widespread distribution of potential year‐round habitats in Ghana, the migratory potential of the local fall armyworm remains strong and is indistinguishable from that of the fall armyworm in China, which undergo seasonal migration.

Silencing of juvenile hormone‐related genes through RNA interference leads to molt failure and high mortality in the spongy moth

Insect Science, EarlyView.
The feasibility of using RNA interference to control the globally important quarantine pest, the spongy moth. Targeting genes related to JHs play an important role in the growth and development of insects. First, the open reading frames (ORFs) of Ldjhamt and Ldjheh were identified and characterized, and the target genes were cloned and double‐stranded ...

The loss of the urea cycle and ornithine metabolism in different insect orders: An omics approach

Insect Molecular Biology, EarlyView.
Among urea cycle enzymes, only the nitric oxide synthase gene is universally present across insect genomes. All Hemiptera species lack the enzymes needed to convert citrulline to arginine, and some also lack the pathway from arginine to ornithine. Putrescine and spermidine synthesis is conserved in all insects, but aphids lack the capability to produce

miR825‐5p‐regulated TNLs govern Arabidopsis resistance to Tetranychus urticae and Pieris brassicae

New Phytologist, EarlyView.
Summary MicroRNAs are essential regulators in plant resistance to biotic stresses, but their specific roles in the plant–herbivore context require deeper investigation. Here, we studied how the Arabidopsis miR825‐5p differentially modulates certain TNLs (MRT1, MRT2, and MIST1), triggering defensive responses against the sucking acari Tetranychus ...

Studies on active chemicals in the saliva of the rice brown planthopper (Nilaparvata lugens) that elicit the production of rice volatiles

浙江大学学报. 农业与生命科学版, 2005
Active chemicals were found to be present in the rice brown planthopper Nilaparvata lugens head extract that induced rice plants to release volatiles attractive to Anagrus nilaparvatae, an egg parasitoid of N.

Zinc Stress Alters Sugar Content in Rice Plants and the Reproduction and Trehalose Metabolism in Nilaparvata lugens

Agronomy, 2022
Excessive zinc (Zn) is toxic to plants, but the effect of zinc-stressed plants on herbivorous insects is still unclear. Hence, we assessed the effect of zinc-stressed rice plants on its feeding pest, Nilaparvata lugens. The soil–rice–N. lugens system was

BpWRKY6 regulates insect resistance by affecting jasmonic acid and terpenoid synthesis in Betula platyphylla

Plant Biotechnology Journal, EarlyView.
Summary Forest pests and diseases pose serious threats to the sustainable development of forestry. Plants have developed effective resistance mechanisms through long‐term evolution. Jasmonic acid and terpenoids play important roles in the defence response of plants against insects.

Planthopper protein Nlsp5 is essential for salivary sheath formation and acts as a HAMP inducing plant resistance to insects

Plant Biotechnology Journal, EarlyView.
Summary During herbivore feeding, plants can recognize herbivore‐associated molecular patterns (HAMPs) present in saliva and trigger pattern‐triggered immunity (PTI). Piercing‐sucking insects secrete gel saliva, forming salivary sheaths that aid in feeding. However, the role of proteins within these salivary sheaths in modulating plant defences remains
