This chapter proposes chronobiology considerations and the manipulation of arthropod biological clocks. The effects of light on circadian and photoperiodic responses are complex and can affect arthropod biology at many levels. The development of methods to alter daily and seasonal rhythms of...

This chapter focuses on the breeding methods, inbreeding depression, epistasis and heterosis in root and tuber crops and bananas (RTBs). The importance of assessing epistasis in diallel crosses in RTB crops are also discussed.

Early classical biocontrol successes in Barbados, some in combination with natural control, were the control of: sugarcane borers, sugarcane mealybugs and West Indian cane fly in sugarcane; cottony cushion scale and citrus blackfly in citrus; coconut whitefly in palm; fall armyworm in vegetables...

Biological control was initiated in Guatemala in the 1990s, after costs for chemicals had increased substantially and had resulted in a drastic decrease in production of, for example, cotton and tomato. Most often, augmentative biocontrol is used in Guatemala. Examples of successful programmes are...

Conservation biological control, implemented in the 1910s by erecting perches in rice fields for insectivorous birds, resulted in effective control of the fall armyworm. Guyana is supposed to be the first country where the tachinid parasitoid Lydella minense, which had been collected in 1932 in...

Biological control in Paraguay started in the 1980s with the use of a baculovirus for augmentative biocontrol of the soybean caterpillar and application of parasitoids to control the sugarcane borer. Since 2000, organic production has stimulated use of biocontrol. Also in 2000, large-scale...

This chapter discusses the agricultural development components of the Char Development and Settlement Project in Bangladesh. These include: support for field crops, homestead agriculture and agroforestry; poultry and livestock; and value chain development. Women's participation in agricultural...

Recently, the expansion of genomic sequencing and genome editing are enabling progress directly in crops themselves. This is key since, while it is highly tractable, Arabidopsis thaliana is a model dicot, and so it will always be important to assess how relevant it is to crop plants. Nevertheless,...

This chapter describes the principles and practices of Apiaceae seed production. While much of the information presented relates directly to carrot seed production, it is also relevant to production of most other Apiaceae seed crops. Where possible, information and examples from other crops have...

This chapter describes the effects of weed interference in carrot and suggests non-chemical (including crop rotations and systems, planting timing, false sowing, use of competitive varieties, mechanical or physical method, flame weeding, reduced tillage, cover crops and mulch, and hand weeding) and ...
