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 ...

Attractiveness of Melon Genotypes to Whitefly (Bemisia tabaci) Mediated by Foliar Morphological and Biochemical Traits

Entomologia Experimentalis et Applicata, EarlyView.
This study identifies melon genotypes resistant to Bemisia tabaci by integrating morphological and biochemical leaf traits. Using free‐choice and no‐choice assays, we demonstrate that resistance is primarily mediated by antixenosis. Genotypes CNPH 11‐1071‐43, CNPH 06‐1047‐343, CNPH 13‐1076, and BG MEL 16 significantly reduced whitefly settling and ...

Unusual Sesquiterpenes from Streptomyces olindensis DAUFPE 5622

In nature, the vast majority of sesquiterpenes are produced by type I mechanisms, and glycosylated sesquiterpenes are rare in actinobacteria. Streptomyces olindensis DAUFPE 5622 produces the sesquiterpenes olindenones A–G, a new class of rearranged ...

Do aphid endosymbiotic bacteria influence parasitoid searching behaviour through changes in aphid honeydew production?

Ecological Entomology, EarlyView.
Hamiltonella defensa infection increases honeydew production in certain aphid genotypes, potentially modifying aphid feeding behaviour. Parasitoid wasps, Aphidius ervi, are more attracted to honeydew from H. defensa‐infected aphids; though larger honeydew amounts may slightly deter searching.
