Integrated Pest Management for Crops and Pastures describes in straightforward language what is required for farmers to successfully implement Integrated Pest Management (IPM) in cropping and grazing operations. It explains the differences between conventional pesticide-based controls and IPM, and demonstrates the advantages of IPM. Effective control of pests depends on a number of approaches, not just chemical or genetic engineering. The opening chapters cover the different approaches to pest management, and the importance of identification and monitoring of pests and beneficials. Most farmers and advisors can identify major pests but would struggle to recognise a range of beneficial species. Without this information it is impossible to make appropriate decisions on which control methods to use, especially where pests are resistant to insecticides. The book goes on to deal with the control methods: biological, cultural and chemical. The biological control agents discussed include both native and introduced species that attack pests. Cultural changes that have led to an increase in the incidence or severity of pest attack are also examined. The chapter on chemical control describes the different ways chemicals can affect beneficial species, also detailing acute, sub-lethal and transient toxicities of pesticides, drawing on examples from horticulture where necessary. Finally, the authors bring all the components of integrated pest management together and show farmers how to put their IPM plan into action.

The investigation was carried out during kharif 2010-2011 and 2011-2012 in order to know the effect of different IPM module on insect pests of soybean. Significantly lower population of (2.54 larvae/ mrl) H.armigera, per cent pod damage (4.23%) by H.armigera were observed in MAU module. The minimum larval population of semilooper (3.62 larvae/mrl), S.litura (2.64 larvae/mrl) and per cent leaflet damage (6.71%) due to leaf miner, the minimum per cent defoliation (10.49%) due to defoliators were observed in chemical control followed by MAU module.

  Insect and mite pests of cotton feed on cotton roots, leaves, stems, and fruit and reduce plant health and productivity, and, subsequently, cotton crop yields. These pests hide in different places on or within the plant or field, which makes them difficult to find and identify and costly to manage. The purpose of this 14-page guide written by Joseph Funderburk, Nicole Casuso, Norman Leppla, and Michael Donahoe and published by the Department of Entomology and Nematology is to provide Florida cotton growers a selected set of options for integrated pest management of insects and mites in cotton fields. It serves as a reference for cultural, mechanical, biological, and chemical control of arthropods. The guide includes links to additional UF/IFAS EDIS articles, as well as external sources of information on arthropod management. The guide also contains a searchable table of registered insecticides, herbicides, and fungicides for Florida cotton.­edis.ifas.ufl.edu/in1111

Abstract Studies on the natural factors contributing to pest regulation are fundamental to developing efficient integrated pest management programs. Chemical control is the main management method used for pests [e.g., Aphis gossypii (Glover)]. The studies of pest management with chemical control provide information that can be incorporated into integrated pest management programs to promote more sustainable pest control approaches. Here, we report the critical stages of A. gossypii and its abiotic and biotic natural mortality factors in cotton crops as a function of plant phenology using a life table. The critical stages of A. gossypii were the first and fourth instars. Together, the abiotic and biotic factors caused 94.31% of the mortality in the A. gossypii populations in cotton crops with plants in the vegetative, flowering, and fruiting stages. The key mortality factors were rainfall and predation. Syrphidae Allograpta exotica (Wiedemann) (Diptera: Syrphidae) and Chrysopidae Chrysoperla externa (Hagen) (Neuroptera: Chrysopidae) larvae, many Coccinellidae species Cycloneda sanguinea (L.) (Coleoptera: Coccinellidae), Eriopsis connexa (Germar) (Coleoptera: Coccinellidae), Harmonia axyridis (Pallas) (Coleoptera: Coccinellidae), Hippodamia convergens (Guérin-Meneville) (Coleoptera: Coccinellidae), Scymnus rubicundus (Erichson) (Coleoptera: Coccinellidae) and Stethorus punctillum (Weise) (Coleoptera: Coccinellidae), one Anthocoridae species Orius insidiosus (Say) (Hemiptera: Anthocoridae), and individuals from the Araneidae family were responsible for the predation of A. gossypii. The results obtained in this study provide support for the idea that efforts to preserve natural enemies (e.g., predators) and rainfall monitoring should be adapted due to their importance for the regulation of A. gossypii populations in all the phenological stages of cotton in tropical regions.

Integrated Pest Management technique is used to formulate a mathematical model by using biological and chemical control impulsively. The uniform boundedness and the existence of pest extinction and nontrivial equilibrium points is discussed. Further, local stability of pest extinction equilibrium point is studied and it has been derived that if T≤T_max, the pest extinction equilibrium point is locally stable and for T>T_max, the system is permanent. It has also been obtained that how delay helps in eradicating pest population more quickly. Finally, analytic results have been validated numerically.

Obstace of pakoba (Syzygium luzonense (Merr.) Merr.) cultivation in nursery is  twig caterpillar (Hyposidra talaca WLK) attacks. The Pest symptoms was holes in the leaves especially young leaves; twig caterpillar enable to attack all leaves of pakoba seed. Severe attacks cause death of seedlings. There are five blocks in pakoba nursery that were observed; 1014 pakoba seedlings were grown in these blocks. The average percentage of twig caterpillar’s attack was quite high, reached 49.34%. Twig caterpillar has been controlled by integrated pest management. Chemical control to decrease twig caterpillars attack in nursery has been done by using half dose of insecticide profenofos.

Abstract. Plant resistance is considered as an important pillar of Integrated Pest Management (IPM), being a highly targeted method since is a less harmful method to the environment, if compared to other tactics such as chemical control. Abiotic factors are those related to the environment and have a direct influence on the dynamics of interaction between insects and plants. The abiotic factors such as altitude, temperature, humidity, luminosity, wind and soil fertility, among others, do not act alone, but in a complex net that leads insect population dynamics in agroecosystems. How the variations of these factors can be studied in the same context? First, it is important to consider how each abiotic factors act separately and then in a coexistence influence over the populations dynamics of insects and plants. In this study, the literature about the influence of abiotic factors on insect herbivory has been reviewed, focusing mainly on the mechanisms in which the plants use in the defense against insects.Influência de fatores abióticos na resistência de plantas a insetos Resumo. A resistência de plantas é considerada um importante pilar no contexto do Manejo Integrado de Pragas (MIP), sendo um método bastante visado por ser menos nocivo ao meio ambiente, quando comparado a outras táticas como o controle químico. Os fatores abióticos são aqueles relacionados ao ambiente e têm influência direta na dinâmica de interação entre insetos e plantas. Os fatores abióticos como altitude, temperatura, umidade, luminosidade, ventos e fertilidade do solo, por exemplo, não atuam sozinhos, mais sim em um complexo de fatores coexistentes que regem as dinâmicas populacionais nos diversos agroecosistemas. Como as variações destes fatores podem ser estudadas em um mesmo contexto? Primeiramente, é importante conhecer como cada uma atua individualmente para então contextualizar em uma situação de coexistência sobre as dinâmicas populacionais de insetos e plantas. Neste artigo, a literatura sobre a influência de fatores abióticos na herbivoria de insetos foi revisada, focando principalmente nos mecanismos em que as plantas utilizam na defesa contra insetos.
