“…Several bacterial species were also identified from CRB in India during the 1960s and 1970s, but pathogenicity was not tested ( Supp Table S1 [online only ]) ( Surany 1960 , Manjunath et al 1969 ). In other reports, Acinetobacter calcoaceticus Beijerinck (Pseudomonadales: Moraxellaceae) and Pseudomonas alcaligenes Monias (Pseudomonadales: Pseudomonadaceae) produced infectivity of more than 50% in India ( Kannan et al 1980 , Sathiamma et al 2001 , Gopal and Gupta 2002 , Gopal et al 2002 ).…”

“…Hololepta quadridentata Oliver and H. columbiana Oliver (Coleoptera: Histeridae) were introduced into Fiji, Palau Islands, and Wallis Island from Trinidad during 1952–1954 but failed to establish ( Hoyt 1957 , Manjunath et al 1969 , Swan 1974 ). Among hemipterans, Platymeris laevicollis Distant (Hemiptera: Reduviidae) was introduced from Tanzania and released into the South Pacific Islands (Papua New Guinea, Western Samoa, and Tonga) during the 1960s ( Vanderpalnk 1958 , Manjunath et al 1969 , Sathiamma et al 2001 , Karim et al 2019 ); however, it failed to establish due to predation of eggs and nymphs from the ant, Pheidole megacephala Fabricius (Hymenoptera: Formicidae) ( Manjunath et al 1969 , Swan 1974 ).…”

“…Scoliid wasps were the most tested parasitoids against CRB, targeting larvae. Elis romandi de Saussure, Scolia cyanipennis Fabricius , Scolia oryctophaga Coquerel , Scolia procera Illiger , Scolia quadripustulata Fabricius, and Scolia ruficornis Fabricius, (Hymenoptera: Scoliidae) were introduced into the Pacific Islands from African and Asian countries during 1940s to 1960s, but most of them never established ( Hoyt 1957 , Manjunath et al 1969 , Swan 1974 , Clausen 1978 , Sathiamma et al 2001 , Manjeri et al 2014 ). Failure to adapt to the tropical Pacific environment is considered to be one of the major factors contributing to lack of establishment ( Swan 1974 ).…”

The coconut rhinoceros beetle (CRB: Oryctes rhinoceros Linnaeus) is one of the most damaging pests to coconut and oil palms in Asia and the Pacific Islands. Adults bore into the crown and damage developing fronds, which affects tree development and yield. The insect is native to South and Southeast Asia and was inadvertently introduced into the Pacific in 1909. It has since spread to several Pacific island nations and territories, causing significant economic impact on these important coconut and palm-growing regions. In the 1950s and 1960s, an international biological control effort was initiated to search for and release natural enemy species. Release of the Oryctes rhinoceros nudivirus Huger (OrNV) and the species complex of Metarhizium Sorokin (Hypocreales: Clavicipitaceae) was successful in controlling CRB in its invaded range. Recently a new biotype of the beetle, known as CRB-G, has spread into the Pacific Islands causing unprecedented levels of damage due to the failure of previously successful biological control agents (BCAs) to suppress this biotype. The re-emergence of CRB as a serious pest warrants a rigorous re-evaluation of potential BCAs and a new search for effective natural enemies if necessary. In this article, we review literature on CRB to 1) analyze past introductions of BCAs and their effectiveness; 2) identify potentially important natural enemies and their geographical origins; and 3) assess possible approaches for utilization of BCAs against the new wave of CRB invasion. Research gaps and directions deserving future attention are highlighted and a strategy for renovation of biological controls for CRB suggested.

“…Indigenous parasitoids play a major role in the management of the coconut black-headed caterpillar in the coconut ecosystem. Field release of the three stage specific Opisina arenosella parasitoids viz Goniozus nephantidis, Elasmus nephantidis and Brachymeria nosatoi at fixed norms and intervals in a heavily infested coconut garden (2.8 ha) for a period of 5 years resulted in highly significant reduction in Opisina population (Sathiamma et al 2000). Follow-up observations revealed that even after 3 years no build-up of the pest was noted in the released site.…”

With increasing hazards due to chemical/synthetic pesticides, the only answer to mitigate these ill-effects is use of safe alternatives. Amongst them, use of natural enemies comprising of parasitoids, predators, entomopathogens, etc. as biological control agents is the most effective, environmentally sound and cost-effective pest management approach to control insect pests. It is anticipated that biological control will play an increasingly important role in integrated pest management (IPM) programs as broadspectrum pesticide use continues to decline. Moreover, biological control is a cornerstone of organic farming, and the production of organic commodities in developed countries like the USA continues to increase at roughly 20 % per year (USDA-ERS 2002). Organic farming is no longer considered a cottage industry since retail sales hit $ 14.6 billion in 2006. For a given arthropod pest or weed, a pool of natural enemies often exists which consists of vertebrates, invertebrates and microorganisms. The fundamental problem in applied biological control is to select an appropriate species or combination of species from this pool that will bring about the desired level of pest suppression with minimal impact on non-target species.

“…Because of the lack of early and obvious exterior indications of RPW infection in date trees, the latter develops predominantly in young 5-to 15-year-old trees. 6,7 Essential oils extracted from plants are utilized as parasite and insect repellents. Numerous studies have demonstrated the contact and fumigant toxicity of plant essential oils and their components to many species of stored product insects at various life stages.…”

This study was conducted to evaluate some terpenes effect on the behavior and immune function of hemocytes in adults of the red palm weevil Rhynchophorus ferrugineus. Six individual different terpenes these are: (±)-menthol, B-citronellol, ( + )-3-carene, (R)- ( + )- limonene, citronella oil and orange terpenes. The results revealed significant differences between the terpenes used on the olfactory response on this insect, in that half of the compounds were very attractive while the other half were repellant to them. This behavior study results with olfactometer citronella oil exhibited an 80% attraction response rate for both sexes, while menthol exhibited a 60% attraction response rate for females and 100% for males. By contrast, menthol had a more significant effect on adults than citronella, lethal concentration at 50 scale (LC50) values of 1.03, 0.89, and 0.9 mg, and LC95 values of 5.09, 2.01, and 1.59 mg, after 24, 48 and 72 h, respectively. For citronella oil, the LC50 values were 2.09, 1.76, and 1.70 mg after 24, 48, and 72 h, and the LC95 values were 5.5, 3.7, and 1.5 mg after 24, 48 and 72h, were noted. In the present study, the effects of citronella and methanol insecticides were observed on six types of hemocytes namely prohemocytes, granulocytes, plasmatocytes, oenocytes, coagulocytes and spherulocytes. Both citronella oil and menthol had a histopathological effect on the hemocytes of the adult red palm weevil, specifically, on the cell membrane, cytoplasm, and nucleus. The findings also revealed that the vacuoles in some hemocytes, specifically, the prohemocytes, plasmatocytes, and granulocytes were more sensitive than those in other hemocytes, which remained unaffected by the treatment. The effects of citronella and menthol on RPW immunity were demonstrated in this study, and this information may be applied to their usage in integrated pest control at sub-lethal dosages.
