“…The safety of microbial control is based on the narrow host range, high specificity, and lack of side effects on other nontargeted organisms. Examples of narrow-host-range entomopathogens are nuclear polyhedrosis viruses (NPVs), granuloviruses, and Microsporidia, while those with a wider host range are nematodes, hypocrealean fungi, and bacteria (Cory and Evans 2007;Garczynski and Siegel 2007;Shapiro-Ilan and Gouge 2002).…”

Insects are a dominant form of life on Earth with more than 1 million described species. Yet, only 1% competes with humans for food, shelter, and space. Various farming systems have been adopted for sustainable pest management but none have been entirely successful in managing insect pests. Chemical insecticides are still the predominant pest control measure but cause health hazard and environmental pollution. The long-term sustainability of agricultural and natural ecosystems depends upon the conservation of natural resources. Conservation agriculture (CA) is a novel approach with a series of practices that strives for acceptable profits together with high and sustained production levels while concurrently conserving the environment. It also increases biodiversity of both flora and fauna which helps to control insect pests, contradictory reports incite concerns regarding reduced yields, increased labor requirements due to avoiding herbicides, and insect pest problems. It is therefore necessary to integrate alternative cultural, biological, mechanical, and appropriate chemical and biotechnological control methods for pest management. The principle of integrated pest management (IPM) creates a balanced environment between sustainable environmental practices and profitable farming. Both IPM and CA work on the same principles to help increase biodiversity and conservation of natural resources. In addition, recent advances in insect pest management like biointensive IPM, precision agriculture (PA) and biotechnology can also synergize the insect pest management in the CA management system. Sustainable pest management for crop production is possible in CA management systems by using IPM in combination with biotechnology and PA.

“…However, only a few of these families, such as Baculoviridae, Poxviridae, and Reoviridae, have potential as biological control agents and have been successfully used in microbial control programs. A common characteristic among these entomopathogenic viruses is that the virions (infective unit) are occluded within a crystalline protein matrix to form an occlusion body (OB) [60], which is a unique characteristic of viruses that infect insects. In these entomopathogenic viruses, OBs have independently evolved as a protective mechanism to environmental factors, which gives the viruses a great advantage as biological control agents [61].…”

“…Their specificity is usually very narrow and often is species specific. Because of their specificity and other characteristics, such as elevated virulence and pathogenicity, BVs are by far the most studied and extensively used as commercial biopesticides for the control of a variety of insect pests in many countries around the world [60,61,73].…”

“…Most BVs have a limited host range and may be species specific in some cases, although there are several NPVs, such as Autographa californica MNPV, Anagrapha falcifera MNPV, and Anticarsia gemmatalis MNPV, which have broader host ranges within the Lepidoptera order [60]. Because of the scarcity of reports on natural isolates of entomopathogenic viruses from Diatraea spp.…”

“…Development of microbial pathogens as viable alternatives to chemical pesticides has been encouraged by public pressure for environmentally benign pest management strategies. Baculoviruses are generally considered ideal candidates for biological control agents because they are naturally occurring and host-specific infecting only a single species or a few closely related species of insects, can cause epizootics in host-insect populations, and persist in the environment for many years [ 1 , 2 , 3 , 4 , 5 ]. Baculoviruses are covalently closed, double-stranded DNA viruses between 85 and 180 kb in size [ 6 ].…”

Field trials and assessments of the balsam fir sawfly (Neodiprion abietis) nucleopolyhedrovirus (NeabNPV: Baculoviridae, Gammabaculovirus) against its natural host were conducted in July and August 2002 near Corner Brook, Newfoundland and Labrador, Canada, in naturally regenerated, precommercially thinned stands dominated by balsam fir (Abies balsamea). Two experimental blocks, each with its own untreated control, were established. The purpose of the Island Pond block was to examine the spread of NeabNPV from a 313-ha aerial treatment block out into adjacent populations of balsam fir sawflies. The purpose of the Old Man’s Pond block (2,093 ha) was to determine whether NeabNPV could disperse into populations of balsam fir sawflies within a 200-m zone between spray swaths. NeabNPV was applied to treatment blocks by a Cessna 188B AgTruck aircraft equipped with MicronAir AU4000 rotary atomizers at an application rate equivalent to 1 × 109 NeabNPV occlusion bodies/ha in 2.5 L of 20% aqueous molasses. At Island Pond, NeabNPV infection increased with time following the spray, especially for individuals close to the treatment block, and infection rate decreased to a measured distance of 400 m from the treatment block. At Old Man’s Pond, NeabNPV infection rose higher (80% vs. 15%) and sawfly densities declined more (84% vs. 60%) in the area between spray swaths than in the control block.
