DOWNLOAD EBOOKFor nearly 50 years, pest control was mostly based on broad-spectrum conv- tional insecticides such as organochlorines, organophosphates, carbamates and pyrethroids. However, the severe adverse effects of pesticides on the environment, problems of resistance reaching crisis proportions and public protests led to stricter regulations and legislation aimed at reducing their use. Ways to reduce the use of synthetic pesticides in plant protection and to use more alternative and novel me- ods for pest control or biorational control are the challenges of pest control for the twenty-first century. The term biorational (biological + rational) pesticides can be defined as the use of specific and selective chemicals, often with a unique modes of action, that are compatible with natural enemies and the environment, with minimal effect on n- target organisms. Biorational control is based on a diversity of chemical, biological and physical approaches for controlling insect pests which results in minimum risk to man and the environment.

DOWNLOAD EBOOK"No one method for the control of the common mealy bug can be recommended under all conditions. The remedy or remedies to be used will depend upon whether the trees are in house lots or orchards, whether few or many, and the infestation light or severe.In the case of sever infestation it will depend also upon the kind of fruit. This insect infects oranges of all varieties, grapefruit, lemons, and all other kinds of citrus fruit grown in California, causing deformity, weakening and dropping of much immature fruit, and the discoloration and weakening of the rind of the fruit maturing. This bulletin discusses the three remedies which have been widely used : namely, fumigation, spraying, and the artificial spread of insect enemies, points out the sphere of usefulness of each method, and shows, on pages 14-15, how they may be combined so as to secure complete control. An important part of the procedure recommended is the banding of trees with a mixture consisting of sulphur and a sticky material used to protect trees from insects. This keeps off the Argentine ant and other ants which attend and foster the mealybug and hinder or prevent the good work of insect enemies which otherwise might hold it in check. The method of preparing the mixture and applying the bands is described on pages 12-13. Where insect enemies are few or absent, or where they are themselves heavily parasitized, the trees should be sprayed or fumigated, and colonies of effective enemies should be introduced." -- p. [2]

DOWNLOAD EBOOKThis book is a compilation of information on all basic aspects of mealybugs, as well as management strategies for mealybug species affecting different crop plants in different countries. It highlights the latest information on morphology, cytogenetics, taxonomy, molecular characterization, biology, damage, ecology, natural enemies, ant association, control measures, insecticide resistance and pheromones – essential aspects which will equip researchers to pursue further research on mealybugs. The book examines current trends in the management of mealybugs for a variety of agricultural and horticultural crops, forest plants and mulberry in different countries, while also addressing the negative effects of chemical control methods and presenting success stories of mealybug control that utilize their natural enemies. It offers a valuable guide for crop growers, government officials and other stakeholders in the industry, as well as researchers and students engaged in related research and development activities.

DOWNLOAD EBOOKTraps baited with sex pheromones were used to monitor field populations of longtailed and obscure mealybugs. Lures loaded with 25 microgram doses of racemic pheromones remained effective for at least 3 months. Pheromones could also be combined to make lures that attracted several species simultaneously. The numbers of insects caught in traps were correlated with mealybug abundance, indicating that pheromone traps can be used in place of laborious manual sampling to monitor populations. The efficacy of using pheromone traps to monitor seasonal fluctuations in mealybug populations was demonstrated.
