The efficacy of synthetic inorganic insecticides to control malaria vector mosquitoes is compromised by increased mosquito resistance to insecticides. Furthermore, use of inorganic insecticides raises serious environmental toxicity concerns. The test plants, Oreosyce africana and Piper capense were identified in Ethiopia through ethnobotanical leads obtained on the basis formal and informal fie...

Background Plants are able to survive in a distinctive environment from its usual one, especially due to morphological or physiological changes, thus a good ability of acclimatization and phenotypic plasticity is present [1]. Light and water availability are decisive factors in a plant’s survival, the occurrence of those is irregular, because luminosity is broadly available on the edges and lar...

Piper nigrum leaves were collected from five locations from Kerala within a radius of 150 km, altitudinal variance of 1000m and annual rainfall variance of 1400mm. The extracted Piper nigrum leaf oil was profiled using a GC-MS, Beta Caryophyllene was the only constituent that was present in all the five locations, of which the highest concentration was noted in the high altitude region of Idukk...

The extraordinary diversity of tropical herbivores may be linked to hostplant specialization driven in part by variation in pressure from natural enemies. We quantified levels of host-specificity and parasitoid attack for the specialist herbivore, Eois (Geometridae). The goals of this research were to examine: 1) whether Eois are specialized on the genus Piper (Piperaceae) and if hostplant spec...
