Perspectives for Synergic Blends of Attractive Sources in South American Palm Weevil Mass Trapping: Waiting for the Red Palm Weevil Brazil Invasion

Coupling several natural and synthetic lures with aggregation pheromones from the palm weevils Rhynchophorus palmarum and R. ferrugineus reveals a synergy that results in an increase in pest captures. The combined attraction of pure pheromones, ethyl acetate, and decaying sweet and starchy plant tissue increases the net total of mass-trapped weevils. The 2018 entrance of the red palm weevil (RPW) into South America has threatened palm-product income in Brazil and other neighboring countries. The presence of the new A1 quarantine pest necessitates the review of all available options for a sustainable mass-trapping, monitoring, and control strategy to ultimately target both weevils with the same device. The effective lure-blend set for the mass-trapping system will attract weevils in baiting and contaminating stations for entomopathogenic fungi that the same weevils will spread.

FAKTOR-FAKTOR YANG MEMPENGARUHI MINAT PETANI KELAPA SAWIT RAKYAT BERPARTISIPASI DALAM SERTIFIKASI PRODUK DI KABUPATEN KAMPAR

Oil palm product certification consists of the Roundtable of Sustainable Palm Oil (RSPO) and the Indonesian Sustainable Palm Oil (ISPO). RSPO certification is a voluntary certificate that must be met by oil palm mills to sell their products in international market. ISPO is a mandatory certificate that must be comply by grower and miller which operate their bisnis in Indonesia. A number of principles and criteria must be comply by smallholders to obtain RSPO certificate. The objective of this study is to analyse farmer perception and factors that influence smallholder participation in certification in Kampar Regency. The population of this study are scheme smallholders (NES/KKPA) and independent smallholders. This study use Summated Likert scale rating to evaluate farmers’ perception and binary logistic regression to assess smallholders participation. The results show that certification is very important while it is important for independent smallholders. Education and land size are factors that influnce scheme smallholders in participating in certification while eduction, land size and job are factors that influence independent smallholders.
