“…However, this 371 manufacturing approach remains unattractive to many companies in North America and Europe 372 that are unfamiliar with mass insect culture as a mainstream production technique, and while, the 373 in vivo production approach remains capable of meeting the current market needs, the ability to 374 produce the amounts of BV needed for large scale field crop protection is far from certain. It 375 remains to be seen if the recent sharp decline in the use of AgMNPV in Brazil after a major 376 investment in laboratory-based mass production facilities (Moscardi et al, 2011;Panazzi, 2013) 377…”

“…Facing future needs for large-scale mass production of BV, in vitro cell culture remains a 385 major approach to overcoming supply and cost constraints that limit BV use (Black et al, 1997, 386 Moscardi et al, 2011). Mass production of hosts to produce viruses has been under development 387 for 30 years but has not yet been successfully scaled up to the levels required to meet 388 commercial acceptability (Granados et al, 2007).…”

The development and use of entomopathogens as classical, conservation and augmentative 26 biological control agents have included a number of successes and some setbacks in the past 15 27 years. In this forum paper we present current information on development, use and future 28 directions of insect-specific viruses, bacteria, fungi and nematodes as components of integrated 29 pest management strategies for control of arthropod pests of crops, forests, urban habitats, and 30 insects of medical and veterinary importance. 31Insect pathogenic viruses are a fruitful source of MCAs, particularly for the control of 32 lepidopteran pests. Most research is focused on the baculoviruses, important pathogens of some 33 globally important pests for which control has become difficult due to either pesticide resistance 34 or pressure to reduce pesticide residues. Baculoviruses are accepted as safe, readily mass 35 produced, highly pathogenic and easily formulated and applied control agents. New baculovirus 36 products are appearing in many countries and gaining an increased market share. However, the 37 absence of a practical in vitro mass production system, generally higher production costs, limited 38 post application persistence, slow rate of kill and high host specificity currently contribute to 39 of Bt toxins, has been conducted over the past two decades. The Bt genes used in insect-resistant 54 transgenic crops belong to the Cry and vegetative insecticidal protein families of toxins. Bt has 55 been highly efficacious in pest management of corn and cotton, drastically reducing the amount 56 of broad spectrum chemical insecticides used while being safe for consumers and non-target 57 organisms. Despite successes, the adoption of Bt crops has not been without controversy. 58

“…This work holds promise for increasing the effectiveness of baculoviruses when used as biopesticides. The use of baculoviruses is a relatively minor area of pest control in agriculture at present, but is forecast to increase dramatically as insecticides are withdrawn or replaced with viral products which possess greater specificity to pest species [88]. However, unlike the culturing, activation and delivery of chitinolytic microbe biopesticides, viruses cannot be grown on purified chitin and need a living organism for their multiplication.…”

A Review of the Applications of Chitin and Its Derivatives in Agriculture to Modify Plant-Microbial Interactions and Improve Crop Yields

Abstract:In recent decades, a greater knowledge of chitin chemistry, and the increased availability of chitin-containing waste materials from the seafood industry, have led to the testing and development of chitin-containing products for a wide variety of applications in the agriculture industry. A number of modes of action have been proposed for how chitin and its derivatives can improve crop yield. In addition to direct effects on plant nutrition and plant growth stimulation, chitin-derived products have also been shown to be toxic to plant pests and pathogens, induce plant defenses and stimulate the growth and activity of beneficial microbes. A repeating theme of the published studies is that chitin-based treatments augment and amplify the action of beneficial chitinolytic microbes. This article reviews the evidence for claims that chitin-based products can improve crop yields and the current understanding of the modes of action with a focus on plant-microbe interactions.

“…A limited number of baculoviruses is used around the globe (Haase, Sciocco-Cap, & Romanowski, 2015;Moscardi, de Souza Lobo, de Castro Batista, Moscardi, & Szewczyk, 2011;Sun, 2015) because practical limitations hamper their commercial development. These include low speed of kill as compared to chemical insecticides, narrow host range and unavailability of suitable isolates for commercialization (Erlandson, 2008;Szewczyk, Hoyos-Carvajal, Paluszek, Skrzecz, & Lobo de Souza, 2006).…”

Spodoptera litura is an emerging insect pest in a wide range of crops worldwide. The insect is difficult to control because of resistance development to synthetic insecticides and emerging resistance to Bacillus thuringiensis toxins. Therefore, there is a need to develop biological control agents, preferably from an indigenous source to avoid risks associated with the importation of exotic natural antagonists. A Pakistani isolate of S. litura nucleopolyhedrovirus (SpltNPV, Baculoviridae), SpltNPV-Pak-BNG, was obtained from the field and characterized biologically and genetically, and compared to a SpltNPV reference isolate, SpltNPV-G1, thought to be of Chinese origin. The dose-mortality response (LD 50 ) of SpltNPVPak-BNG was not significantly different from that of the reference isolate SpltNPV-G1, but the time-to-death (LT 50 ) was significantly shorter for SpltNPV-Pak-BNG than for SpltNPV-G1. DNA restriction enzyme profiling indicated that SpltNPV-Pak-BNG and SpltNPV-G1 are different viruses. Sequence analysis of 'ORF24', specific for SpltNPV (and S. littoralis NPV as ORF21), and the conserved baculovirus core genes polyhedrin, DNApol, pif-2 and lef-8 confirmed that this was indeed the case and that SpltNPV-Pak-BNG is a genuine SpltNPV variant, whereas the SpltNPV-G1 isolate we used is, in fact, a SpliNPV variant, renamed to SpliNPV-G1. The newly isolated SpltNPV-Pak-BNG has the potential for development as a biocontrol agent of S. litura in Pakistan.ARTICLE HISTORY
