Rice is the staple food crop for more than half of the world’s population though it’s cultivation is done in only 11% of the world’s cultivable land. Several pests attack rice in different ways at different stages. Increased reliance on pesticides for pest control is found to be unsustainable and cost-ineffective. So, Integrated Pest Management (IPM) has been introduced as the best alternative for pest management in rice. IPM in rice helps to minimize risks to the environment and human health. Rice IPM uses the combination of cultural, use of resistant varieties, biological, physical, and chemical practices for pest control. Farmers Field School has been the most effective way to increase IPM knowledge among rice farmers. Such training helps to facilitate the farmers to apply ecologically informed farming practices. There are several challenges regarding the implementation of rice IPM. To increase IPM implementation in rice emphasis should be given on farmers’ training and education. The role of government is also vital for the successful implementation of IPM. This review article provides an overview of various IPM practices being performed in rice fields at present.

Abstract An expectation for optimal integrated pest management is that the instantaneous numbers of natural enemies released should depend on the densities of both pest and natural enemy in the field. For this, a generalised predator–prey model with nonlinear impulsive control tactics is proposed and its dynamics is investigated. The threshold conditions for the global stability of the pest-free periodic solution are obtained based on the Floquet theorem and analytic methods. Also, the sufficient conditions for permanence are given. Additionally, the problem of finding a nontrivial periodic solution is confirmed by showing the existence of a nontrivial fixed point of the model’s stroboscopic map determined by a time snapshot equal to the common impulsive period. In order to address the effects of nonlinear pulse control on the dynamics and success of pest control, a predator–prey model incorporating the Holling type II functional response function as an example is investigated. Finally, numerical simulations show that the proposed model has very complex dynamical behaviour, including period-doubling bifurcation, chaotic solutions, chaos crisis, period-halving bifurcations and periodic windows. Moreover, there exists an interesting phenomenon whereby period-doubling bifurcation and period-halving bifurcation always coexist when nonlinear impulsive controls are adopted, which makes the dynamical behaviour of the model more complicated, resulting in difficulties when designing successful pest control strategies.

Intercropping of aromatic plants provides an environmentally benign route to reducing pest damage in agroecosystems. However, the effect of intercropping on natural enemies, another element which may be vital to the success of an integrated pest management approach, varies in different intercropping systems. Rosemary, Rosmarinus officinalis L. (Lamiaceae), has been reported to be repellent to many insect species. In this study, the impact of sweet pepper/rosemary intercropping on pest population suppression was evaluated under greenhouse conditions and the effect of rosemary intercropping on natural enemy population dynamics was investigated. The results showed that intercropping rosemary with sweet pepper significantly reduced the population densities of three major pest species on sweet pepper, Frankliniella intonsa, Myzus persicae, and Bemisia tabaci, but did not affect the population densities of their natural enemies, the predatory bug, Orius sauteri, or parasitoid, Encarsia formosa. Significant pest population suppression with no adverse effect on released natural enemy populations in the sweet pepper/rosemary intercropping system suggests this could be an approach for integrated pest management of greenhouse-cultivated sweet pepper. Our results highlight the potential of the integration of alternative pest control strategies to optimize sustainable pest control.

Purpose of study: For the previous couple of years, sugarcane crop production is under crisis for many reasons. This study aimed at exploring those reasons impeding the potential production of sugarcane in the Rahim Yar Khan district of Punjab, Pakistan. Methodology: A total of 343 randomly selected sugarcane growers participated in this study as respondents. Data were collected through face-to-face interview techniques on a structured and validated questionnaire. Data were analyzed using both descriptive and inferential statistics through the Statistical Package for Social Sciences (version 22). Results: Quantitative results indicated that the total production of sugarcane during the last two years dropped from 833 to 636 mounds per acre. The chi-square analysis confirmed that production, protection, climatic changes policy and financially associated factors had statistically significant (P<0.05) inverse impacts on sugarcane production. In contrast, the marketing factors were statistically non-significant for the production of sugarcane (P>0.05). The qualitative findings as perceived by key informants confirmed that non-availability of disease-resistant varieties, traditional irrigation mechanism, lack of proper plant protection measures, Integrated Pest Management (IPM), climate change, high cost of production, and sluggish policy had pressurized the sugarcane production. Recommendations: It is suggested that the development of insect pests, diseasesand drought-resistant varieties should be launched. Efficient and alternate row irrigation system, climate change adoption strategies, integrated pest management, mechanized farming of sugarcane should be adopted in order to curtail the production cost and increase the level of production. Novelty: Studies have been conducted to investigate the influencing factors on the yield of sugarcane but this is the first study that indicates the association of those factors that are hampering on-farm production of sugarcane crop in district Rahim Yar Khan, Punjab, Pakistan.

Aim: Information on the influence of water availability during different seasons of rainfed or irrigated agriculture as it relates to insect pest population build-up in crops could assist in the development of integrated pest management. A study was therefore conducted to investigate effects of spacing, pest infestation and control on cucumber under rainfed and irrigated conditions. Place and Duration of Study: At the Teaching and Research Farm, Ekiti State University, Ado Ekiti, Nigeria during the 2016/2017 rainy and dry seasons. Methodology: The experiment was laid out using randomized complete block design (RCBD) in a split-plot arrangement in five replications, with spacing (60 x 60 cm, 60 x 90 cm and 60 x 120 cm) as the main plot treatments and the sub-plot treatments were different pest control strategies. The pest control strategies include synthetic insecticide (Lambda-cyhalothrin), botanical insecticide (Anogeissus leiocarpus) and control. Growth parameters and yield attributes were recorded. Insect pest occurrence, their build-up and percentage infestation on cucumber and the efficacy of the management strategies were monitored. Results: The results showed that yield was enhanced in irrigated system with the widest spacing of 60 x 120 cm botanical treatment interaction. Bemisia tabaci was the most prominent insect pest attacking cucumber under irrigated system. Conclusion: Other cultural control practices such as the use of trap crops with little or no financial implication should also be added to botanical pesticides as an integrated pest management tactic for effective management and control of the pest.

A considerable amount of scientific time has been spent defining Integrated Pest Management (IPM). The following is quoted from an Extension Committee on Organization and Policy publication (4): “Integrated Pest Management (IPM) is a system that utilizes all suitable pest control techniques and methods to keep pest populations below economically injurious levels. Each pest control technique must be environmentally sound and compatible with production and user objectives. Integrated Pest Management is more than chemical pesticide management. In many cases it includes biological, cultural, and sanitary control practices for all pest complexes.”

Invertebrate pest control within both agricultural and horticultural production systems continues to present many challenges. Over the past decades the commonly used method for pest control has been the direct application of chemical products. However, in response to environmental, economic, and other problems associated with the over-reliance on chemical insecticides there has been an increasing drive towards the development of Integrated Pest Management (IPM) approaches. Many IPM strategies are now well developed under protected environments. However, within the open field in many situations targeted success is yet to be achieved. This special issue will seek to showcase original articles and reviews by leading research entomologists and associated experts. Articles presented will focus on the development and implementation of IPM strategies against various major arable and horticultural invertebrate pests (both indigenous and invasive species).

Despite competition from other natural and man-made fibres cotton remains the world's most important textile, of great economic importance in many of the countries in which it is grown. It is prone to a number of pests which reduce yield and the control of these presents many problems. While integrated pest management can solve many of these, some use of insecticides cannot be avoided.
