Red palm weevil Rhynchophorus ferrugineus Olivier (Coleoptera: Curculionidae; Rhinoceros beetle Oryctes rhinoceros Linn. (Coleoptera: Scarabidae) and Black headed caterpillar Opisina arenosella Walker (Lepidoptera: Oecophoridae) are the three among major insect pests of coconut in India. Grubs of Red palm weevil (RPW) enter and complete their life cycle within the stem, killing the tree, adults of Rhinoceros beetle (RB) feed on the growing point of the tree and cause yield loss and the larvae of black headed caterpillar scrape and feed on the green part of the coconut leaflets leading to burnt symptoms of the fronds, death of young trees and yield loss. Aggregation pheromones of RPW and RB are used for monitoring and mass trapping of RPW and RB to manage the pest under economic threshold level. During 2006-07 large scale field trials for RPW and RB were carried out in four different states in India by PCI under a partially funded Coconut Development Board (CDB) project using indigenously synthesized pheromone lures. It was demonstrated that the pheromone lures predominantly attracted virgin and gravid females of RPW and RB. Female sex pheromone of black headed caterpillar Opisina arenosella was also identified and developed in India by PCI, under a project partially funded by CDB; dispensers, dosage and traps were standardized under field conditions and further trials were also conducted in India. It was also established that pheromone lures can be used as a monitoring and a surveillance tool for understanding the pest status before the release parasitoids and natural enemies.

The World

Date palm offshoots represent an important source of planting material in many date palm-growing countries around the world. Infestation by the red palm weevil ((RPW) Rhynchophorus ferrugineus), the longhorn beetle ((LHB) Jebusaea hammerschmidti) and the rhinoceros beetle ((OB) Oryctes spp.) hinders commercialization and movement of these offshoots. An effective quarantine protocol, with exposure period of 72 h at 25 °C using ECO2FUME (EF) with phosphine concentration of 1500 ppm has been developed for date palm offshoots against these coleopteran internal tissue borers.

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.

Significant Difference

Red Palm Weevil (RPW), Rhynchophorus ferrugineus is a lethal pest which has been described as a serious pest that reduces the production of coconut tree and other major cultivated palms. RPW infestation was initially detected by Department of Agriculture (DOA) in 2007 in all eight Terengganu districts. Rhu Tapai plantation area is one of the highly infested areas in Terengganu. Until now, limited reports on population abundance of this lethal pest have been discussed particularly in Rhu Tapai. Therefore, a study on population abundance is a must in order to understand the population dynamic of RPW which will be the first step of its control strategy. A total of 12 traps were installed and synthetic pheromones (P028 Ferrolure+) were used in attracting the RPW adults. Overall, 81 individuals of RPW were successfully collected after 16 weeks of pheromone trapping (3rd September until 28th November 2018). The trend of weekly RPW captured was eventually decreasing from Week 1 to Week 16 but showed a sudden increment in Week 10. Pandan cultivar plot captured the highest number of adult RPW compared with Mawa cultivar plots. Result showed no significant difference between RPW sexes percentage of sexes which was 53% of male and 47% of female (1:1 ratio) (U= 0.143, p > 0.05). Daily rainfall and temperature significantly reduced the trapping efficiency (R²rainfall = 0.142, p = 0.145; R²temperature = 0.0858; p = 0.258). These results will be the baseline information for future study regarding control management strategy using pheromone-based mass trapping system.

AbstractThe red palm weevil (RPW), Rhynchophorus ferrugineus (Olivier), is one of the most destructive pests of date palm in United Arab Emirates. We conducted field trials in Abu Dhabi from May 2010 to April 2011, to evaluate the effect of weekly stirring of water and dates in the RPW pheromone trap on adults captured in brown and white traps, using a randomized complete block design with four treatments and five replications. Each trap contained: (1) a dispenser of the RPW male aggregation pheromone (Ferrolure™) containing 700 mg of the active ingredient (4-methyl-5-nonanol (90%) + 4-methyl-5-nonanone (10%)) at 95% purity; (2) an ethyl acetate (EA) dispenser (Weevil Magnet™) containing 40 ml of the active ingredient of EA at 98% purity; (3) 350 g of fodder date fruits; and (4) 4 L of water. Mean adults captured in white traps was 22.5 ± 0.50 and 16.8 ± 0.41 adults/trap/month with and without stirring, respectively, while in brown traps the mean was 39.9 ± 1.31 and 28.3 ± 0.51, respectively. The overall mean of adults captured was 31.2 ± 6.21 and 22.6 ± 4.81 adults/trap/month with and without stirring, respectively. The highest number of weevils caught was in the brown traps with stirring, while the lowest was in the white traps without stirring. The results of these trials suggest the use of brown traps containing aggregation pheromone, 350 g of date fruits, EA and water. It is necessary to stir the water with dates in the traps to increase their efficacy.

IPM or Integrated pest management is a strategy that integrates various methods of cultural, physical, mechanical, biological control and selection of pesticides as the last option.  IPM is not only cost effective but simultaneously prioritized human and environmental safety. IPM is based on farmer’s local knowledge, acceptance and education.  Several insects were reported as coconut pests in Asia and Pacific region.  Among these pests, rhinoceros beetle, red palm weevil, coconut hispine beetle, coconut black headed caterpillar and coconut scale currently causing severe damage to coconut palms in the region.  Rhinoceros beetle, Oryctes rhinoceros Linnaeus (Coleoptera: Scarabaeidae) is native to South Asia and Southeast Asia.  Management of this pest is a combination of sanitation in plantations and surrounding, biological control by using Metarhizium anisopliae, Oryctes virus and pheromone trapping. Red palm weevil, Rhynchophorus ferrugineus Olivier (Coleoptera: Curculionidae) outbreaks usually occur after infestation of rhinoceros beetle. Keeping the rhinoceros under control results in keeping the red palm weevil under control too.  Pheromone trapping is also developed for reduction of this pest. Coconut hispine beetle, Brontispa longissima (Gestro) (Coleoptera: Chrysomellidae), is an invasive pest occurs in Southeast Asia and Pacific region.  Biological control of the pest is recommended by releasing two species of parasitoids, Asecodes hispinarus Boucek (Hymenoptera: Eulophidae) and Tetrastichus brontispae Ferriere (Hymenoptera: Eulophidae). Coconut black headed caterpillar, Opisina arenosella Walker (Lepidoptera: Oecophoridae) is one of the key pests of coconut in South Asia and invaded Thailand in 2008.  Management of this pest in its native region consisted of: 1) removing and burning of the infested leaves; 2) biological control by releasing parasitoids such as Goniozus nephantidis (Muesebeck), Bracon brevicornis (Wesmael), Brachymeria nephantidis Gahan; and 3) chemical control by trunk injection and applying systemic insecticides in the holes. Bacillus thruringiensis has been recommended for biological control of the black headed caterpillar in Thailand.  Coconut scale, Aspidiotus destructor Signoret (Hemiptera: Diaspididae) has been reported as a serious in Philippines.  Predators are significant biological control agents in limiting A. destructor populations.  The most common natural enemies associated with the coconut scales are the coccinellid beetles Chilocorus spp., Azya trinitatis, Cryptognatha nodiceps, Rhyzobius lophanthae and Pentilia castanea. Local parasitoids, Comperiella, Aphytis and Encarsia also play important roles in keeping the pest under control.  Application of insecticides could inducee the infestation of the scale. Biological controls is recommended for suppression of other coconut pests, such as slug caterpillars (Lepidoptera: Limacodidae) such as Parasa lepida Cramer; coconut leaf moth, Artona catoxantha Hampton (Lepidoptera: Zygaenidae); and coconut leafminer, Promecotheca cumingii Baly (Coleoptera: Chrysomelidae).
