The insecticidal activity of Piper nigrum fruit-derived piperidine alkaloid (piperine) and N-isobutylamide alkaloids (pellitorine, guineensine, pipercide and retrofractamide A) against female adults of Culex pipiens pallens and Aedes aegypti was examined. On the basis of 24-h LD50 values, the compound most toxic to female C. pipiens pallens was pellitorine (0.4 µg/♀) followed by guineensine (1.9 µg/♀), retrofractamide A (2.4 µg/♀) and pipercide (3.2 µg/♀). LD50 value of chlorpyrifos was 0.03 µg… 
Isolation of a larvicidal compound from Piper solmsianum C.DC. (Piperaceae)
TLDR
Eupomatenoid-6 is evaluated as a potent insecticide with relatively low toxicity for mammals and is shown to be effective against Ae.
A biodegradable device for the controlled release of Piper nigrum (Piperaceae) standardized extract to control Aedes aegypti (Diptera, Culicidae) larvae.
TLDR
The device provided controlled release of Piper nigrum extract with residual activity for 37 days and may represent an effective alternative for the control of Aedes aegypti larvae in small water containers.
Plant Natural Products for the Control of Aedes aegypti: The Main Vector of Important Arboviruses
TLDR
This review details plant species and their secondary metabolites that have demonstrated insecticidal properties (ovicidal, larvicidal, pupicidal, adulticidal, repellent and ovipositional effects) against the mosquito, together with their mechanisms of action.
Isolation and insecticidal activity of aliphatic chain amides isolated from Piper hancei
Six aliphatic chain amides, including chingchengenamide A(C1), N-isobutyldeca-trans-2trans-4-dienamide(C2), retrofractamide A(C3), piperlonguminine(C4), N-p-coumaroyltyramine(C5) and
Repellency of essential oils against Nephotettix cincticeps: Laboratory and glasshouse assays
TLDR
Linalool was the best repellent among the single‐tested compounds under laboratory conditions and in the glasshouse study, the highest repellency was observed in the mixture of linalool and piperine.

TLDR
QSAR modelling was used to find synergists to combine with deltamethrin for increasing its efficacy against resistant strains of Ae.

Larvicidal activity of isobutylamides identified in Piper nigrum fruits against three mosquito species.
TLDR
Structural-activity relationships indicate that the N-isobutylamine moiety might play a crucial role in the larvicidal activity, but the methylenedioxyphenyl moiety does not appear essential for toxicity.
A review of Piper spp. (Piperaceae) phytochemistry, insecticidal activity and mode of action
TLDR
The conclusions of the current work with Piperaceae are that Piper extracts offer a unique and useful source of biopesticide material for controlling small-scale insect out-breaks and reducing the likelihood of resistance development when applied as a synergist with other botanical insecticides such as pyrethrum.
