“…are known to have a beneficial use in agriculture, such as oil palm. Cotesia sp., for instance, is an important natural enemy to bagworm (Psychidae; Metisa plana) , an important pest to the oil palm plantations of Peninsular Malaysia (Halim et al 2018). As the location of study sites in Sungai Rembau and Sungai Sepetang are located next to oil palm plantations, these beneficial insects may move across the boundaries and colonise the adjacent plantations and then exert their beneficial effects upon the pests in the agricultural plantations.…”

Riparian areas hold vast number of flora and fauna with exceptional contributions to the ecosystem. A study was conducted in Sungai Sepetang, Sungai Rembau and Sungai Chukai to identify the insect community in a riparian zone of Peninsular Malaysia. Sampling was conducted in six consecutive months from December 2017 to May 2018 during both day and night using sweep nets. Twenty sampling stations (S1-S20) had been assembled along the riverbanks with an average distance of 200 m between each station. The 17,530 collected insects were from 11 orders and consisted of Diptera, Coleoptera, Hemiptera, Hymenoptera, Lepidoptera, Neuroptera, Orthoptera, Blattodea, Thysanoptera, Mantodea and Odonata. The three most abundant orders were Diptera (33.84%; 5933 individuals), Coleoptera (28.82%; 5053 individuals) and Hemiptera (25.62%: 4491 individuals). The collected insect community consisted of different guilds such as the scavenger, predator, herbivore, pollinator and parasitoid. Sungai Sepetang and Sungai Rembau were dominated by mangrove flora, Sonneratia caseolaris (Myrtales: Lythraceae), while Sungai Chukai was dominated by Barringtonia racemosa. There was a significant difference (p < 0.05) in the composition of insects between the three rivers though clustering analysis showed that the insect communities in Sungai Sepetang and Sungai Rembau were 100% similar compared to Sungai Chukai which consisted of a totally different community. There is a significant negative correlation between abundance of insects with salinity and wind speed at Sungai Chukai and Sungai Sepetang.

“…The outbreak of M. plana can cause 50% of leaves defoliation and yield loss of up to 40-47% over two consecutive years of serious infestation ( Figure 1E) [13]. The current pest management control of the insect in oil palm plantations involves chemical pesticides, biopesticides, and biological control.…”

Bagworm, Metisa plana (Lepidoptera: Psychidae) is a ubiquitous insect pest in the oil palm plantations. M. plana infestation could reduce the oil palm productivity by 40% if it remains untreated over two consecutive years. Despite the urgency to tackle this issue, the genome and transcriptome of M. plana have not yet been fully elucidated. Here, we report a comprehensive transcriptome dataset from four different developmental stages of M. plana, comprising of egg, third instar larva, pupa and female adult. The de novo transcriptome assembly of the raw data had produced a total of 193,686 transcripts, which were then annotated against UniProt, NCBI non-redundant (NR) database, Gene Ontology, Cluster of Orthologous Group, and Kyoto Encyclopedia of Genes and Genomes databases. From this, 46,534 transcripts were annotated and mapped to 146 known metabolic or signalling KEGG pathways. The paper further identified 41 differentially expressed transcripts encoding seven genes in the chitin biosynthesis pathways, and their expressions across each developmental stage were further analysed. The genetic diversity of M. plana was profiled whereby there were 21,516 microsatellite sequences and 379,895 SNPs loci found in the transcriptome of M. plana. These datasets add valuable transcriptomic resources for further study of developmental gene expression, transcriptional regulations and functional gene activities involved in the development of M. plana. Identification of regulatory genes in the chitin biosynthesis pathway may also help in developing an RNAi-mediated pest control management by targeting certain pathways, and functional studies of the genes in M. plana.

“…M. plana is a common pest in oil palm ecosystem which causing 33% to 40% of crop loss by defoliating on the palm fronds. The insect family such as Braconidae, Ichneumonidae and Chalcididae is very dominantly associated with the bagworm species, Metisa plana which successfully use in controlling the number of M. plana in the plantation [20]. T. ulmifolia apparently are able in attracting beneficial insect as well as C. cobanensis.…”

Beneficial flowering plants play a vital role in attracting beneficial insects such as parasitoid that controls insect pests. In order to evaluate the effectiveness of two species of flowering plants as beneficial hedgerow plants, we identify insects communities of T. ulmifolia and M. malabathricum, which generally grown on roadside. We also compared the insects community of both plants based on time of the day. A total of 5,029 insect individuals were collected through three sampling occasions from five sampling stations of T. ulmifolia and five sampling stations of M. malabathricum. Chi-square test showed that there was a significant difference (χ2=37.3848, df=1, P<0.05) between the composition of insect communities on M. malabathricum and T. ulmifolia. The insect visiting M. malabathricum were similar at both night and day while T. ulmifolia attracted different insect community depending on the time of the day. The results suggested that different plant species would attract a different community of insects. T. ulmifolia success in attracting the visitation of beneficial insect but its effectiveness is limited to a short period of time. Meanwhile, the effectiveness of M. malabathricum as beneficial plant is yet illuminated.
