Weed suppression by cover cropping is considered as a viable alternative to herbicidal control. This study0020was, therefore, conducted during 2010-2012 in a Malaysia oil palm plantation to characterize oil palm weed communities and evaluate oil palm yield under four different perennial cover-crop systems. Experimental treatments included four different cover crop combinations such as Axonopus compressus, Calopogonium caeruleum + Centrosema pubescens, Mucuna bracteata, Pueraria javanica + Centrosema pubescens, and herbicidal control by glufosinate-ammonium and weedy control. Weed composition in the un-weeded treatment was different from that of cover crop treatments. The un-weeded treatment favored Paspalum conjugatum and A. compressus as the dominant species. In the A. compressus and C. caeruleum + C. pubescens treatments the associated weed species with highest dominance was Asystasia gangetica, while the weeds A. compressus and A. gangetica were associated with M. bracteata and P. javanica + C. pubescens treatments. In the weeded treatment receiving 6 sprays of glufosinate- ammonium over the two years, B. -

High infestation was reported in Miri, Mukah and Sibu. Censuses on the infestation of T. rufivena were conducted at three different locations, i.e. in Miri (young palm), Mukah (mature palm) and Sibu (ablation samples). Samples for census were taken from infested bunches, female and male inflorescences. The census was done by chopping the bunches and the female inflorescences while for the male inflorescences, the bottom of spikelets were cut to determine the number of live larvae and pupae. The census 44 Serangga reveiled that in Sibu, a high infestation of T. rufivena was found on male inflorescences compared to bunches of female inflorescences. The mean number of live larvae found in male inflorescences for the first and second day of census recorded 35.3 ± 15.7 and 14.0 ± 7.3, respectively. The highest number of live larvae recorded from male inflorescences was 207 and 65, respectively. Meanwhile, the mean number of live larvae from infested bunches and female inflorescences on the first day were 9.9 ± 3.5 and 19.4 ± 4.4, respectively. -
Emerging and Re-Emerging Biotic Stresses of Agricultural Crops in India and Novel Tools for Their Better Management
GENERAL ARTICLES Emerging and re-emerging biotic stresses of agricultural crops in India and novel tools for their better management J. Kumar*, R. K. Murali-Baskaran, S. K. Jain, P. N. Sivalingam, J. Mallikarjuna, Vinay Kumar, K. C. Sharma, J. Sridhar, P. Mooventhan, A. Dixit and P. K. Ghosh Food security of our country is at risk due to heavy yield losses of agricultural crops caused by pests and diseases known together as biotic stresses. Conventional management practices in vogue are not competent under the current situations obscured by the incitants of biotic stresses which have either enhanced their offensive capabilities due to adaptive mutations or regained their patho- genic/herbivory potential owing to climate change. Numerous causal agents of biotic stresses are also introduced in the country or new regions of the country either through natural dispersal as invasive species, or on account of quarantine irregularities at national or international levels. Therefore, it is of utmost importance to appraise the impact of these new biotic stresses burgeoned in the recent past and to develop novel technologies for their management. To devise an effective preventive and eradicative strategy for containing these biotic stresses, new research innovations need to be practiced such as deciphering basic/molecular mechanism of host-pathogen/insect inte- ractions; endophytic mechanisms of plant protection; nanotechnology in pest management; host resistance strengthening by gene cloning, recombinant DNA technologies, RNA biology, utilizing gene editing technologies such as CRISPR/Cas9, etc. This article presents a comprehensive account of new biotic stresses of agricultural crops built up in the country and also reviews the novel scien- tific inventions made worldwide which can be further employed to devise more efficient methods for alleviating impact of these biotic stresses of food crops in the country. -

Giant Palm Weevils of the Genus Rhynchophorus (Coleoptera: Curculionidae) and Their Threat to Florida Palms
DACS-P-01719 Pest Alert created 18-February-2010 Florida Department of Agriculture and Consumer Services, Division of Plant Industry Adam H. Putnam, Commissioner of Agriculture Giant Palm Weevils of the Genus Rhynchophorus (Coleoptera: Curculionidae) and Their Threat to Florida Palms Michael C. Thomas, Taxonomic Entomologist, Florida Department of Agriculture and Consumer Services, Division of Plant Industry INTRODUCTION: The giant palm weevils of the genus Rhynchophorus Herbst are among the worst palm pests in the world. One species, Rhynchophorus cruentatus (Fabricius), is native to Florida and the southeastern US. Two other species, Rhynchophorus ferrugineus (Olivier) and Rhynchophorus palmarum (L.), are found in the New World and are considered to be threats to palms in Florida. Of particular concern is R. ferrugineus, known as the red palm weevil. It is a pest of coconut and other palms in its native range. Over the past three decades, its range has expanded into the Middle East, North Africa and Mediterranean Europe. It attacks many palm species, but is especially devastating on date palms. It recently became established in Curaçao in the Caribbean, placing it ever closer to Florida. In each case, it is suspected that the weevils travelled with imported palms. In January 2010, the federal government prohibited the importation into the United States of live palms belonging to 17 genera. IDENTIFICATION: Identification of adult palm weevils is straightforward as they are the largest weevils in NorthAmerica, ranging from about 1 to 1.8 inches (25mm to 45mm) in length. The individual species are rather similar, but the three species under consideration can be distinguished by the following key: 1. -

Insecticides application is inevitable to prevent economic loss. However, to protect insect pollinators which co- habitat with the pest and reduce the risk of resistance development among the pest to insecticides, rotation treatments with more than one pollinator-friendly insecticides is recommended. This paper examines the effectiveness of rotating several pollinator-friendly insecticides in controlling the pest. To assess the effectiveness of different rotation combination, a field study on a seven-year-old peat estate was carried out using several insecticides combinations and application intervals, then the level of infestation post-treatment was assessed. Significantly, the results showed that only four single rounds of insecticides application in a year would yield relatively better control than nine rounds of Bacillus thuringiensis applications. Overall, there was no significant difference in clean bunches percentages obtained between five rounds of treatment compared to only four rounds per year. The result strengthens our confidence that the optimum and most cost-effective approach for one-year protection against T.
