Resumen
Biological pest control techniques usually have identifiable costs and constraints that they must overcome before they will be adopted by farmers. Many biological control agents are developed in the public sector and need economic assessments at an early stage. The methods often have hidden costs related to farm labor adjustments or initial costs of development. Living biological controls frequently escape, and they may be disrupted by pesticides, regulations, or farm commodity programs. Pest control registration procedures and small markets also present obstacles. Area-wide implementation programs and changes in incentives for researchers may speed development and adoption of biological controls.

Resumen
IPM or Integrated pest management is a strategy that integrates various methods of cultural, physical, mechanical, biological control and selection of pesticides as the last option. IPM is not only cost effective but simultaneously prioritized human and environmental safety. IPM is based on farmer’s local knowledge, acceptance and education. Several insects were reported as coconut pests in Asia and Pacific region. Among these pests, rhinoceros beetle, red palm weevil, coconut hispine beetle, coconut black headed caterpillar and coconut scale currently causing severe damage to coconut palms in the region. Rhinoceros beetle, Oryctes rhinoceros Linnaeus (Coleoptera: Scarabaeidae) is native to South Asia and Southeast Asia. Management of this pest is a combination of sanitation in plantations and surrounding, biological control by using Metarhizium anisopliae, Oryctes virus and pheromone trapping. Red palm weevil, Rhynchophorus ferrugineus Olivier (Coleoptera: Curculionidae) outbreaks usually occur after infestation of rhinoceros beetle. Keeping the rhinoceros under control results in keeping the red palm weevil under control too. Pheromone trapping is also developed for reduction of this pest. Coconut hispine beetle, Brontispa longissima (Gestro) (Coleoptera: Chrysomellidae), is an invasive pest occurs in Southeast Asia and Pacific region. Biological control of the pest is recommended by releasing two species of parasitoids, Asecodes hispinarus Boucek (Hymenoptera: Eulophidae) and Tetrastichus brontispae Ferriere (Hymenoptera: Eulophidae). Coconut black headed caterpillar, Opisina arenosella Walker (Lepidoptera: Oecophoridae) is one of the key pests of coconut in South Asia and invaded Thailand in 2008. Management of this pest in its native region consisted of: 1) removing and burning of the infested leaves; 2) biological control by releasing parasitoids such as Goniozus nephantidis (Muesebeck), Bracon brevicornis (Wesmael), Brachymeria nephantidis Gahan; and 3) chemical control by trunk injection and applying systemic insecticides in the holes. Bacillus thruringiensis has been recommended for biological control of the black headed caterpillar in Thailand. Coconut scale, Aspidiotus destructor Signoret (Hemiptera: Diaspididae) has been reported as a serious in Philippines. Predators are significant biological control agents in limiting A. destructor populations. The most common natural enemies associated with the coconut scales are the coccinellid beetles Chilocorus spp., Azya trinitatis, Cryptognatha nodiceps, Rhyzobius lophanthae and Pentilia castanea. Local parasitoids, Comperiella, Aphytis and Encarsia also play important roles in keeping the pest under control. Application of insecticides could inducee the infestation of the scale. Biological controls is recommended for suppression of other coconut pests, such as slug caterpillars (Lepidoptera: Limacodidae) such as Parasa lepida Cramer; coconut leaf moth, Artona catoxantha Hampton (Lepidoptera: Zygaenidae); and coconut leafminer, Promecotheca cumingii Baly (Coleoptera: Chrysomelidae).

Resumen
Pests are major constraints to the effective growth and development of every crop through their damage, and can be controlled effectively by the use of their natural enemies which is referred to as the biological pest control. In this study, the biological control model of cassava pests through optimal control theory was presented in order to minimize the population of the pests and stabilize the natural enemies population so as not to affect the crop negatively. A mathematical model was formulated via the Lotka-Volterra model, and the model was characterized. The optimality system was established, the equilibrium point with its uniqueness was established for the model. Finally, stability analysis of the model was investigated through optimal control approach and numerical data were employed to validate the system. The results obtained showed that cassava pests can be effectively controlled biologically. Keywords: Optimal control, Cassava pest, Biological control, Stability, Natural enemies

Resumen
AbstractThe aphids, Cinara cupressi (Buckton), Eulachnus rileyi Williams and Pineus pini (Macquart), have invaded conifer plantations in southern and eastern Africa between 1968 and 1986. Conifer plantations, and particularly pine plantations, are a new habitat in this region, having been established in the 1960s and 1970s. These aphids are the first non-native pests to colonize these forest plantations. As exotic pests, the aphids are suitable targets for classical biological control through the importation of natural enemies from Europe, the region of origin of the three aphids. The opportunities for biological control are explored and the prospects are encouraging. Details of the natural enemy complexes of the target pests in Europe are provided and discussed in relation to previous successful biological control programmes against conifer pests in other continents.

Resumen
The use of biological control for the management of pest insects pre-dates the modern pesticide era. The first major successes in biological control occurred with exotic pests controlled by natural enemy species collected from the country or area of origin of the pest (classical control). Augmentative control has been successfully applied against a range of open-field and greenhouse pests, and conservation biological control schemes have been developed with indigenous predators and parasitoids. The cost–benefit ratio for classical biological control is highly favourable (1 : 250) and for augmentative control is similar to that of insecticides (1 : 2–1 : 5), with much lower development costs. Over the past 120 years, more than 5000 introductions of approximately 2000 non-native control agents have been made against arthropod pests in 196 countries or islands with remarkably few environmental problems. Biological control is a key component of a ‘systems approach’ to integrated pest management, to counteract insecticide-resistant pests, withdrawal of chemicals and minimize the usage of pesticides. Current studies indicate that genetically modified insect-resistant Bt crops may have no adverse effects on the activity or function of predators or parasitoids used in biological control. The introduction of rational approaches for the environmental risk assessment of non-native control agents is an essential step in the wider application of biological control, but future success is strongly dependent on a greater level of investment in research and development by governments and related organizations that are committed to a reduced reliance on chemical control.

Resumen
This work reviews the historical and current pest risks and research concerning seed storage in the Czech Republic (CR). Stored seed pests (i.e. animals causing injuries to the germ and endosperm) represent a high risk of economic damage due to the high value of seeds coupled with long-term seed storage in small storage units (e.g., boxes, satchels). Rodents represent a significant risk to all types of seeds, especially seeds stored in piles or bags. Mites, psocids, and moths are the main pests of stored grass and vegetable seeds: mites can decrease seed germinability by 52% and psocids caused 9.7% seed weight loss in broken wheat kernels after 3 months of infestation under laboratory conditions. Although beetles (Sitophilus sp., Tribolium sp., Oryzaephilus sp.) and moths (Plodia sp.) are common pests of grain seeds (e.g., wheat, barley, maize), two serious seed pests, Sitotroga cereallela and S. zemays, are rare in the CR. Bruchus pisorum is a common pest of pea seeds, while other Bruchids are rare in the Czech legume seed stores. Currently, the control of seed pests is becoming difficult because the efficient pesticides (e.g., methylbromide, dichlorvos, drinking anticoagulant rodent baits) for seed protection have been lost without the development of adequate substitutes. New research on seed protection in the CR using biological control (mite predators Cheyletus sp.), low pressure, modified atmospheres, and hydrogen cyanide is overviewed. &nbsp;

Resumen
The aim of the present work is to study the dynamics of stage-structured pest control model including biological control, i.e. by releasing of natural enemies and infected pests periodically. It is assumed that only immature susceptible pests are attacked by natural enemies admitting Beddington DeAngelis functional response and mature susceptible pests are contacted by infected pests with bilinear incidence rate and become exposed. The sufficient condition for local stability of pest extinction periodic solution is derived by making use of Floquet’s theory and small amplitude perturbation technique. The global attractivity of pest extinction periodic solution is also established by applying comparison principle of impulsive differential equations.

Resumen
The main constraints to increase mungbean production in Indonesia are pests and diseases. The application of integrated biological agents can improve the efficacy of controlling the mungbean pests and diseases. The study aimed to determine the efficacy of integrated biological agents to suppress mungbean pests and diseases. This field research was conducted from May to July 2018 using a randomized block design with seven treatments and four replicates. The treatments were: T1 = Trichol + NSP, T2 = Trichol + SlNPV, T3 = Trichol + NSP + SlNPV, T4 = Trichol + NSP + SlNPV + BeBas, T5 = Trichol + NSP + SlNPV + BeBas + GE, T6 = chemical pesticides, and T7 = control. The results showed that the highest efficacy occurred in T4 and T5 treatments which saved the yield loss from major pests and diseases attack, and did not differ significantly with chemical pesticides (T6). Treatments T4 was able to reduce the development of soil borne diseases by 3% and suppress Spodoptera litura attack by 9.8% as compared to chemical treatment. T4 was also more efficient than T5 because it uses less biological agents. The advantage of biological agents is compatible if they were used together with predators such as Oxyopes sp., Paederus sp. and Coccinella sp; and also Telenomus sp. and Trichogramma sp. parasitoids. On the other hand, the chemical pesticides (T6) killed all existing natural enemies. Therefore, T4 could be recommended for controlling mungbean pests and diseases.

Resumen
AbstractThe number of species of insect pests, estimated to be maximally 10,000 worldwide, forms only a small part of the millions of species of plant-eating insects. Chemical pest control is becoming increasingly difficult and objectionable in terms of environmental contamination so that other methods of pest control need to be developed. One of the best alternatives is biological control. Natural and inoculative biological control has already proven successful against a variety of pests over large areas. One is inclined to forget, however, how successful a biological control program has been as soon as the pest problem has been solved. Other types of biological control involving the regular introduction or augmentation of natural enemies are better known, although these have been applied on a much smaller scale; a survey of the present-day application of these latter types of biological control is presented here. Phases in the implementation of biological control are illustrated and needed future developments in research are discussed. The main limitation on the development of biological control is not the research, since natural enemies are easier found and with a much lower investment than new chemical pesticides, but rather the attitudes held by growers and disinterest on the part of industry, policy-makers, and politicians. The first priority for those concerned with the development and application of safer pest control should, therefore, be to change the perceptions that these other groups have of biological control.

Resumen
AbstractOrganic producers have traditionally understood the value of conserving the natural enemies of the pests of the crops they grow. An equal appreciation of the value of importing new species of natural enemies is also needed. Given this understanding, the interests of organic farmers could then be promoted by efforts to stimulate greater activity by government agencies in charge of such importations. Furthermore, the focus of such importations could be altered to target more precisely pests of crops most commonly grown by organic producers. This would benefit organic farmers by permanently solving or greatly reducing the intensity of problems from many introduced crop pests. The potential benefit of a coordinated federal and state program of classical biological control could be very large for organic farmers. There is an increasing interest nationwide in expanding the use of classical biological controls. Organic producers now have the opportunity to add their influence to this trend to reshape the country's pest control agenda away from chemicals and toward biological controls and to focus this at least in part on those pests of greatest concern to organic producers. To do so, however, organic producers will have to learn a new lesson, i.e., the difference between native and imported pests and the value of importation as a means to control the latter.

Resumen
Natural ways of biocontrol are the best option to combat insect pests for ensuring maximum protection against crop failure. Since Nepal is blessed with natural resources, a huge number of biological control agents are available for the exploration of possible management of insect pests without causing any deleterious effects on the environment. They are less toxic, stable, and of no side effects when used in crop fields. The present generation of farmers is in dire need of sustainable biocontrol strategies that ensure optimum crop protection against harmful pests. This paper emphasizes various such biocontrol options that are capable of checking the pest population to prevent farmers from going through economic loss due to crop failure. Control measures with direct natural origin must be preferred over chemically synthesized ones if we hope to leave this Earth for our future generations as well. Researches on this field are still scanty. But with the healthy collaboration of government, research bodies ad local farmers, they could lead to the ultimate solution of insect pests through biological control methods soon.

Resumen
AbstractBiological control of arthropod pests has a long history of useful practical application. Parasites, predators, and pathogens have been employed in many cases to control pest arthropods in an efficient, cost-effective, and permanent manner. The traditional tactics used in biological control (classical, augmentation, and conservation) remain vital and valuable tools in the biological control of pests for agricultural crops, range lands, forests, and glasshouses. New technologies offer promise. One emerging technique involves the genetic improvement of natural enemies of arthropods through selection, hybridization, or recombinant DNA technology.

Resumen
AbstractThe new association approach for selecting biological control agents has been reanalyzed in the light of recent data. The results support the conclusion that the new association approach is ecologically and statistically sound. One of the major advantages of this approach is its capacity to control native pests, which make up 60–80% of all pests. The specificity of biocontrol agents newly associated with the target hosts is similar to other biocontrol agents. In addition, the new association approach is as safe as the old association approach in terms of environmental risks. Recent trials in the use of new associations have been most encouraging, and suggest that this approach should contribute to the future success of biological pest control worldwide.

Resumen
The classical biological control technique of introducing two or more populations of the same species of beneficial agent to increase the genetic diversity of that species (and so increase the chances of achieving a successful project) is reviewed. From standard literature sources, all cases of multiple introductions of conspecific populations against insect targets were listed and the effect of subsequent introductions on the outcome of the project was recorded. Of 178 projects identified, involving 417 separate importations, only 11 (6.2%) were successful through a second or later importation of the same morphologically defined species of beneficial agent. Of these, five involved host-related "strains" that are likely to be cryptic species, so the success rate for the introduction of conspecific populations falls to 3.4%. The possibility that some (or even all) of the other six cases also involved cryptic species awaits investigation. Our analysis demonstrates that introducing two or more populations of the same species is less likely to result in enhanced success than if other species of natural enemies are sought for "normal" classical biological control (historical success rate 12–16%). In our discussion we focus on the genetic theory of species which underpins this area of applied biology and find that there is also no theoretical support for the continued introduction of strains.

Resumen
In this paper, we propose two impulsive differential systems concerning biological and, respectively, integrated pest management strategies. In each case, it is observed that there exists a globally asymptotically stable susceptible pest-eradication periodic solution on condition that the amount of infective pests released periodically is larger than a certain critical value. When the amount of infective pests released is less than this critical value, the system is shown to be permanent, which implies that the trivial susceptible pest-eradication solution loses its stability. Further, the existence of a non-trivial periodic solution is also studied by means of numerical simulations. In the case in which a single control is used, one can only use the amount of infective pests which are periodically released in order to control pests at desirable low levels, while in the case in which integrated management is used, one can use the proportion of pests removed by means of spraying chemical pesticides together with the amount of infective pests which are periodically released to control pests at desirable low levels.

Resumen
In the article, 10 species of pests that damage rice plants during the season in the rice agrobiocenosis were identified. Leptestheria dahalacensis Sars, Apus concriformis Sh., Corn stalk Ostrinia nubilalis Hb, and Cephus pygmaeus have been reported to cause damage to rice grasses.A growth calendar has been developed. In the pest experiment during the rice germination period, biological effectiveness of the drug was the highest for 15 days, accounted for 93.9%, in the variant treated with Nurell D 55% em.k at rate of 1.5 l/ha. When the variant was treated with Tayshin 500 s.d.g (Clothianidin) at rate of 0.06 kg/ha, the effectives of the drug were 93.3% in 14 days. In the experiment, Nurell D 55% em.k (1.5 l/ha) was used against the main pests (0.06kg/ha) yielded 70.7 q/ha in the variant in which the chemical agent was used, and 10.1 additional yields were reported. The results showed that the yield of “Iskandar” variety was 73.8 q/ha, which was 13.2 q/ha more than the control, when Nurell D 55% em.k (1.5 l/ha) against the main pests was applied. Whereas new chemical Tayshin 500 s.d.g. (0.06kg/ha) was used in the variant, in which the yield was 70.7 q/ha, and it was more by 10.1 q/ha than the control variant.

Resumen
AbstractThe extent to which pests should be managed by biological versus chemical methods has been a burning public policy issue since about 1950. A thorough policy analysis is needed to facilitate movement beyond the status quo. Such analysis should: a) review the extent of adoption of ecologically selective methods of pest control that have emerged from the last three decades of research, b) examine changes in policies, legislation and institutional arrangements that would foster more rapid and widespread adoption of environmentally benign pest controls, c) assess the role of biological controls in facilitating survival of farms during periods of economic adversity and in increasing the competitiveness of American agriculture, d) evaluate opportunities to use ecologically selective pest controls to improve water quality, to reduce environmental impacts of pests and of farming practices, and to preserve the usefulness of pest-resistant crop cultivars and pesticides, and e) identify options and mechanisms to further increase the flow of private and public resources into biocontrol research, development and implementation. A committee of highly accomplished and respected citizens needs to be formed to conduct a thorough analysis of the above and other issues related to the long-term economic viability of farming and to the development and widespread adoption of agricultural practices that will conserve and improve the resource base, and that are devoid of negative impacts on the environment and public health.

Resumen
Indonesia is one of the largest rice producing countries in the world. In rural areas, the majority of the population has a livelihood as rice farmers. Being a farmer also has several obstacles, one of which is the attack of planthopper on rice plants. This makes the yield less optimal. Farmers must be vigilant from the outset against planthopper pests. Onward with the development of technology, farmers can use information technology as a learning tool to detect planthopper pests early and control them. The result of the development of information technology that every community uses and owns is an Android-based smartphone. For this reason, with the socialization of the application of early detection of planthopper pests and their control using biological agents can help farmers in managing rice plants. The app is made based on Android, so farmers can install the application into a smartphone to detect planthopper pests. Whereas for the control of planthopper pests selected using Biological Agent, because Biological Agents are a safer way to control planthopper pests than using pesticides. By utilizing Android applications and biological agents, farmers are expected to get maximum yields.Keywords—: Rice; Wereng Pest; Socialization; Biological Agents.

Resumen
The fall armyworm (FAW), Spodoptera frugiperda, is one of the most important invasive pests worldwide, resulting in considerable losses in host crops. FAW comprises two genetic strains, such as the “rice strain”, which prefers rice and other grass species, and the “maize strain”, which feeds upon maize and sorghum. Potential control measures are generally more applicable to the farmers who lack financial assets to buy chemical insecticides or costly pure seeds. The adverse effects of pesticides on the ecosystem and human’s health and the development of resistance to insect pests have exaggerated efforts to find an alternative strategy that is cost-effective, low-risk and target-specific. Therefore, biological control is widely considered as one of the most important options for insect pest management. This comprehensive review amasses the information on biological control in all phases of their development, including predators, parasitoids, entomopathogenic fungi, viruses, nematodes, bacteria, and biopesticides, with a special focus on their effectiveness against FAW. The findings regarding biological control are briefly discussed in light of improving management programs of the invasive pest S. frugiperda.

Resumen
Crop monocultures encourage the multiplication and spread of pest insects on massive and uniform crop. Numerous studies have evaluated the impact of plant diversification on pests and beneficial arthropods population dynamics in agricultural ecosystems and provided some evidence that habitat manipulation techniques like intercropping can significantly influence pest control. This paper describes various potential options of habitat management and design that enhance ecological role of biodiversity in agroecosystems. The focus of this review is the application and mechanisms of biodiversity in agricultural systems to enhance pest management.
