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).

Palm Weevil

The red palm weevil (RPW) (Rhynchophorus ferruginous) is one of the most serious pest insects threatening the sustainability of the date palm sector (Phoenix dactylifera L.). Nevertheless, a gap exists in the body of knowledge regarding patterns in farmers’ adoption of integrated pest management (IPM) for RPW control and how their knowledge of RPW symptomology influences IPM adoption. Data were collected using structured questionnaires from 183 palm growers in Al-Ahsa Governorate, Saudi Arabia. The results indicate that most farmers had insufficient knowledge to visually diagnose RPW symptoms and damage. Farmers moderately adopted preventive measures recommended for protection from RPW infestation. Only 13.11% of the farmers exhibited a high rate of adoption of pest management practices for RPW control and eradication. The findings revealed a strong positive association (0.8, p < 0.01) between the knowledge level regarding symptoms and IPM adoption level, whereby the respondents with more knowledge of RPW symptoms showed a higher level of adoption in all IPM categories. This study contributes to the development of our understanding of the social behaviors and risks associated with RPW. This might enhance the quality of awareness campaigns and extension programs and assist in developing a visual inspection protocol for RPW infestation for farmers.

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.

Palm Weevil

Red Palm Weevil (RPW), Rhynchophorus ferrugineus Olivier, is a notorious pest, which infests palm trees and has caused great economic losses worldwide. At present, insecticide applications are still the main way to control this pest. However, pesticide resistance has been detected in the field populations of RPW. Thus, future management strategies based on the novel association biological control need be developed. Recent studies have shown that the intestinal tract of RPW is often colonized by multiple microbial species as mammals and model insects, and gut bacteria have been found to promote the growth, development and immune activity of RPW larvae by modulating nutrient metabolism. Furthermore, two peptidoglycan recognition proteins (PGRPs), PGRP-LB and PGRP-S1, can act as the negative regulators to modulate the intestinal immunity to maintain the homeostasis of gut bacteria in RPW larvae. Here, we summarized the current knowledge on the gut bacterial composition of RPW and their impact on the physiological traits of RPW larvae. In contrast with metazoans, it is much easier to make genetic engineered microbes to produce some active molecules against pests. From this perspective, because of the profound effects of gut bacteria on host phenotypes, it is promising to dissect the molecular mechanisms behind their effect on host physiology and facilitate the development of microbial resource-based management methods for pest control.

AbstractSeveral studies have investigated palm trees’ microbiota infected with red palm weevil (RPW) (Rhynchophorus ferrugineus), the major pest of palm trees. This study compared the microbial communities of infected and uninfected palm trees in the Hail region, Northern Saudi Arabia, determined by high-throughput 16S rRNA gene sequencing by Illumina MiSeq. The results indicated that taxonomic diversity variation was higher for infected tree trunk than the healthy tree trunk. Soil samples from the vicinity of healthy and infected trees did not have a significant variation in bacterial diversity. Myxococcota, Acidobacteriota, and Firmicutes were the dominant phyla in RPW-infected tree trunk, and Pseudomonadaceae was the most prominent family. This study is the first report on the characterization of RPW-infected and healthy palm trees’ microbiome.

The red palm weevil (Rhynchophorus ferrugineus) is a highly destructive pest of oil palm, date, and coconut in many parts of Asia, Europe, and Africa. The Food and Agriculture Organization of the United Nations has called for international collaboration to develop a multidisciplinary strategy to control this invasive pest. Previous research focused on the molecular basis of chemoreception in this species, particularly olfaction, to develop biosensors for early detection and more effective bait traps for mass trapping. However, the molecular basis of gustation, which plays an essential role in discriminating food and egg-laying sites and chemical communication in this species, is limited because its complete gustatory receptor gene family still has not been characterized. We manually annotated the gene family from the recently available genome and transcriptome data and reported 50 gustatory receptor genes encoding 65 gustatory receptors, including 7 carbon dioxide, 9 sugar, and 49 bitter receptors. This study provides a platform for future functional analysis and comparative chemosensory study. A better understanding of gustation will improve our understanding of this species’ complex chemoreception, which is an important step toward developing more effective control methods.
