Lippia umbellata Cav.: Chemical Composition, Insecticidal, and Antimicrobial Activities

Chemistry &Biodiversity, Volume 23, Issue 8, August 2026.
Hexane extracts of Lippia umbellata leaves and flowers contain lupenone, α‐amyrin, and hentriacontane. They exhibit insecticidal activity against Drosophila melanogaster and inhibit AChE in vitro and in silico. Furthermore, the extracts can inhibit the growth of medically important bacteria and yeasts, including multidrug‐resistant strains.

How does leaf age affect performance? A comparative study of essential oils from young and mature Eucalyptus globulus leaves in crop protection

Pest Management Science, Volume 82, Issue 8, Page 7510-7525, August 2026.
Leaf age influences metabolomic profiling but not bioactivity of Eucalyptus globulus essential oils. Leaf age affects volatile levels of young and adult E. globulus oils, but not their bioactivity. Young leaf essential oil had higher contents of α‐ and β‐pinene. AEEO had higher levels of 1,8‐cineole and trans‐pinocarveol.

Fitness Costs of Resistance to Bacillus thuringiensis in the Pink Bollworm Pectinophora gossypiella

, 2009
Resistance to Bacillus thuringiensis (Bt) cotton, Gossypium hirsutum, is associated with fitness costs in pink bollworm, Pectinophora gossypiella. Previous work has demonstrated that costs of resistance are induced by environmental factors including ...

Binding and Oligomerization of Modified and Native Bt Toxins in Resistant and Susceptible Pink Bollworm. [PDF]

PLoS ONE, 2015
Insecticidal proteins from Bacillus thuringiensis (Bt) are used extensively in sprays and transgenic crops for pest control, but their efficacy is reduced when pests evolve resistance.

Molecular mechanisms of sex determination in Lepidoptera: current status and perspectives

Insect Science, Volume 33, Issue 2, Page 599-617, April 2026.
The genetic basis of sex determination in Lepidoptera was discovered in 2014 in the silkworm Bombyx mori. In this model species, the W chromosome‐derived small piRNA called Fem piRNA downregulates the expression of a Z‐linked gene, Masculinizer (Masc), which leads to the default female‐specific splicing of the doublesex gene (dsxF) and thus to female ...

Synthetic biology approaches to generate temperature‐sensitive alleles for the Sterile Insect Technique

Insect Science, Volume 33, Issue 2, Page 517-532, April 2026.
Abstract The Sterile Insect Technique (SIT) is an environmentally friendly, sustainable pest control approach, which uses large‐scale releases of sterile insects to suppress or eradicate target populations through infertile matings. The efficiency of SIT is enhanced by male‐only releases requiring genetic sexing strains (GSSs) that are classically ...
