“…Opisina arenosella (Lepidoptera: Oecophoridae) or commonly called the coconut black-headed caterpillar is a harmful defoliator of coconut in many coconut producing countries including India, Sri Lanka (Kumara, 2015), Bangladesh (APPPC, 1987), Pakistan, Myanmar (EPPO, 2014), China (Baoqian et al, 2016;Jin et al, 2018), Thailand (DOA Thailand, 2017) and Malaysia (Nor Ahya et al, 2018). Being polyphagous by nature, this pest also found infesting other crops such as oil palm, jackfruit, cashew (Shameer et al, 2017), date palm, and numerous types of ornamental palms (Murthy & Jalai, 2003).…”

Many coconut producing countries in Asia are facing a serious infestation of Opisina arenosella (Lepidoptera: Oecophoridae) or commonly called the coconut black-headed caterpillar. Recently, the pest has been detected in the coconut (Cocos nucifera) planting area in Pahang, Malaysia. Thus, an initiative to manage the pest by using parasitoids has been started with a study on the effects of diet on survival, longevity and reproduction of naturally occurred parasitoid known as Trichospilus pupivorus (Hymenoptera: Eulophidae). The aim of this study was to identify suitable concentrations of honey that can be used in developing its rearing technique. Two independent experiments were conducted, i.e., a) survival and longevity study; and b) reproduction study. In each study, different honey concentrations were tested on ten (eight replications) and one (five replications) female parasitoids respectively. 30% honey concentrations resulted in high survival rate of the adult during early life with relatively prolonged longevity up to 6.0±0.19 days and significantly produced the highest number of progenies (105.4±0.81). The lowest survival rate was given by 60% honey and significant longevity up to 6.5±0.33 days with no progenies. Further studies on other plausible factors affecting the reproduction and fitness of progenies should also be investigated to ensure efficient rearing techniques.

“…Meanwhile, by deploying 40-120 cross-vane traps baited with (ZZZ)-3,6,9-tricosatriene traps per ha, BHC populations are directly reduced. In other assays, a density of 100 pheromone traps per ha resulted in a 34-94% reduction in larval infestation pressure over consecutive generations (Chandrashekharaiah, 2013;Kumara et al, 2015). While these studies underscore the efficacy of semiochemicalbased approaches, other scientists have been skeptical about the feasibility or cost-effectiveness of pheromone-based approaches (Fernando and Chandrasiri, 1997;Cork and Hall, 1998).…”

Ecology, invasion history and biodiversity-driven management of the coconut black-headed caterpillar Opisina arenosella in Asia

et al. 2023

The coconut black-headed caterpillar (BHC), Opisina arenosella Walker (Lepidoptera: Xyloryctidae) is an important herbivore of palm trees that originates in South Asia. Over the past decades, O. arenosella has spread to several countries in Eastern and Southeast Asia. BHC larval feeding can cause severe defoliation and occasional plant death, resulting in direct production losses (e.g., for coconut) while degrading the aesthetic value of urban and rural landscapes. In this review paper, we systematically cover taxonomy, bio-ecology, invasion history and current management of O. arenosella throughout Asia. Given that O. arenosella is routinely controlled with insecticides, we equally explore options for more sustainable management through agroecological and biodiversity-based tactics e.g., cultural control or biological control. Also, recent advances in chemical ecology have unlocked lucrative opportunities for volatile-mediated monitoring, mating disruption and mass-trapping. Substantial progress has been made in augmentation biological control, with scheduled releases of laboratory-reared parasitoids lowering BHC infestation pressure up to 95%. Equally, resident ants provide 75-98% mortality of BHC egg masses within the palm canopy. Biological control has been effectively paired with sanitary measures and good agronomy (i.e., proper fertilization, irrigation), and promoted through participatory farmer training programs. Our comprehensive listing of non-chemical preventative and curative tactics offer bright prospects for a more environmentally-sound, biodiversity-driven mitigation of a palm pest of regional allure.

“…Coconut is, however, attacked by more than 800 species of pests. In India and Sri Lanka, one of the major pests is the coconut leaf eating caterpillar Opisina arenosella Walker (Lepidoptera: Oecophoridae), with outbreaks causing serious damage to coconut and other palms, typically via feeding on the underside of leaves whilst protected by a gallery made of frass and silken threads (Nirula 1956 ; Mohan and Sujatha 2006 ; Singh and Rethinam 2006 ; Kumara et al 2015 ; Fig. 1 .).…”

Direct and indirect influences of intercrops on the coconut defoliator Opisina arenosella

et al. 2017

Coconut palm (Cocos nucifera) infestation by Opisina arenosella (Lepidoptera: Oecophoridae) in the Indian subcontinent may occur in November to May each year in the same or adjoining areas of plantations. Parasitoids of O. arenosella may also be consistently present at these times. During other periods, pests and/or parasitoids could be maintained on intercrops that are commonly grown throughout the year. Field surveys of 54 intercrop species in Kerala, India, found that O. arenosella attacks banana, but not others, while laboratory screening showed that O. arenosella can mature on jack fruit, cashew and oil palm. Larvae of 20 lepidopteran species found on intercrops were screened for use by Goniozus nephantidis (Hymenoptera: Bethylidae), a larval parasitoid of O. arenosella, which oviposited on two species but its offspring failed to mature. Thirteen intercrop herbivore species were screened for use by Brachymeria nosatoi (Hymenoptera: Chalcididae), a pupal parasitoid of O. arenosella, which completed development on the pyralids Herculia nigrivita, Syllepte derogata and Psara basalis. Further, connectance trophic webs were compiled using prior field records of coconut, 33 species of intercrops, 58 species of lepidopteran herbivores and 29 species of primary parasitoids. Both laboratory and literature evidence suggests that populations of O. arenosella are unlikely to be maintained by feeding on intercrops or strongly influenced by direct competition with other lepidopterans but are likely to be affected by sharing parasitoids. Intercrop herbivores have clear potential for maintaining parasitoids of O. arenosella, and we recommend thirteen plant species as intercrops that should aid in conservation biocontrol.
