Book Description
The current research aimed to study biological control of pest thrips Frankliniella occidentalis (PERGANDE) (Thy., Thripidae), Thrips tabaci LINDEMAN (Thy., Thripidae) and Gynaikothrips ficorum (MARCHAL) (Thy., Phlaeothripidae) using predatory bug species: Geocoris ochropterus FABR. (Het., Lygaeidae), Montandoniola moraguesi (PUTON) (Het., Anthocoridae), Orius similis ZHENG (Het., Anthocoridae) and Scipinia subula HSIAO et REN (Het., Reduviidae). Firstly, the biology and prey consumption of the four predatory bug species were experimented at temperature 25oC. In further research, G. ochropterus, which displayed high prey consumption, fecundity and long longevity, was selected to study its biology and prey consumption at temperatures 18 and 30oC. After that, its prey consumption in changing prey offer, the effect of extreme temperatures, its prey preference for prey ages and species, the effect of the different nutritions, as well as its cannibalism and the intraguild predation with O. similis were determined at temperature 25oC. Finally, greenhouse experiments were conducted to confirm the efficiency of G. ochropterus for the biological control of the pest thrips. Under laboratory conditions, the results showed that all the tested predators, except S. subula, were able to complete their life cycles with the three pest thrips species as prey at temperature 25oC. Among them, G. ochropterus was the most superior in terms of prey consumption, fecundity and longevity. Further experiments revealed that G. ochropterus displayed shorter life cycle, lower mortality, higher fecundity and daily prey consumption at temperature 30oC than at 18oC. In addition, G. ochropterus showed the adaptability to changing prey offer. It also developed well with considerably high prey consumption at extremely high constant and changing temperatures (35 and 35/25oC). Under extremely low temperature 3 and 6oC, the adults of G. ochropterus showed high tolerance. Moreover, G. ochropterus could exhibit prey preference for certain life stages of thrips, and clearly preferred pest thrips to the non-thrips prey species. Different nutritions affected the development and survival period of G. ochropterus, with the adult predators living for a considerable period of time on 10% honey emulsion. Its cannibalism and intraguild predation with O. similis occurred in the experiments, and reduced with sufficient prey availability. Under greenhouse conditions, releasing a pair of G. ochropterus adults per plant caused up to 92.1, 85.7, and 83.7% reductions in the populations of F. occidentalis, T. tabaci and G. ficorum, respectively.

Book Description
Thrips (fhysanoptera) are very small insects, widespread throughout the world with a preponderance of tropical species, many temperate ones, and even a few living in arctic regions. Of the approximately 5,000 species so far identified, only a few hundred are crop pests, causing serious damage or transmitting diseases to growing crops and harvestable produce in most countries. Their fringed wings confer a natural ability to disperse widely, blown by the wind. Their minute size and cryptic behavior make them difficult to detect either in the field or in fresh vegetation transported during international trade of vegetables, fruit and ornamental flowers. Many species have now spread from their original natural habitats and hosts to favorable new environments where they often reproduce rapidly to develop intense damaging infestations that are costly to control. Over the past decade there have been several spectacular examples of this. The western flower thrips has expanded its range from the North American continent to Europe, Australia and South Africa. Thrips palmi has spread from its presumed origin, the island of Sumatra, to the coast of Florida, and threatens to extend its distribution throughout North and South America. Pear thrips, a known orchard pest of Europe and the western United States and Canada has recently become a major defoliator of hardwood trees in Vermont and the neighboring states. Local outbreaks of other species are also becoming problems in field and glasshouse crops as the effectiveness of insecticides against them decline.

Book Description
India is especially suitable for agricultural products, its vast plains containing alluvial soil with rich natural contents. The major economy of India is based on agricultural products. The green revolution in India brought high hopes for Indian farmers. Several new scientific information helped crop production to grow by leaps and bounds: the more researches, the more intricacies. Further knowledge of pests makes scientists consider several new solutions. The use of chemicals was immediately adopted to decimate the population of pests and, at first, good results were obtained. But later on, harmful effects of the pesticides became known. It was realized later on that the regular use of chemicals in pesticides is extremely dangerous for human health. Generally, chemical pesticides are used to curb the harmful effects of insects and pests. But the immediate gain of this process has an adverse effect on the environment in the long run. Regular use of chemicals leads to insecticide resistance. Then, biodiversity is distributed by pest resurgence and pesticide residues. So, the immediate gain of one generation creates serious problems for the next generation. To sustain agriculture towards its natural mode some new solutions are to be traced. The solution to reduce pesticides is present in the preference for biological management. Predators and parasitoids may be used as natural enemies. In order to gain control over the thrips pests by less harmful means for the agricultural crops, more research work needs to be done. Certain other methods have to be explored in favour of the environment, biodiversity and other useful flora and fauna. We need to maintain the tritrophic interactions in which eating relationships between several species may be traced for biological control.

Book Description
Biological control – utilizing a population of natural enemies to seasonally or permanently suppress pests – is not a new concept. The cottony cushion scale, which nearly destroyed the citrus industry of California, was controlled by an introduced predatory insect in the 1880s. Accelerated invasions by insects and spread of weedy non-native plants in the last century have increased the need for the use of biological control. Use of carefully chosen natural enemies has become a major tool for the protection of natural ecosystems, biodiversity and agricultural and urban environments. This book offers a multifaceted yet integrated discussion on two major applications of biological control: permanent control of invasive insects and plants at the landscape level and temporary suppression of both native and exotic pests in farms, tree plantations, and greenhouses. Written by leading international experts in the field, the text discusses control of invasive species and the role of natural enemies in pest management. This book is essential reading for courses on Invasive Species, Pest Management, and Crop Protection. It is an invaluable reference book for biocontrol professionals, restorationists, agriculturalists, and wildlife biologists.

Book Description
Over the years farmers have over relied on chemical pesticides as the main strategy for controlling pests in French beans. Consequently, there has been a pest resurgence, environmental damage, pest resistance as well as lethal effects on non target beneficial organisms. A shift to the more environment friendly biological control of pests is therefore prudent. This book explores and provides an insight on the potential of Entomopathogenic nematodes, Heterorhabditis bacteriophora, and Steinernema karii, as a biological control agent against flower thrips, Frankliniella occidentalis and Megalurothrips sjostedti in French beans.The book will be found especially useful to all proponents of biological pest control and more so to researchers and other professionals in search of biological pest control. All persons interested in exploiting the potential of EPNs as a biological Agent will also find the book useful
