Ecology, Biology, Damage, and Management of Sucking and Chewing Insect Pests of Citrus

Abstract

Citrus are important commodities for human and animal nutrition but these crops are attacked by a plethora of dangerous agents, including viruses, bacteria, fungi, and invertebrates that decrease the yield significantly. Within invertebrates, insects are the more prevalent citrus pests causing plant damage or act as diseases vector. In this chapter, we focused in the insect pests with worldwide distribution in citrus orchards, including sap sucking Asian citrus psyllid Diaphorina citri, citrus mealybug Planococcus citri, citrus whitefly Dialeurodes citri, thrips representatives such as Scirtothrips citri and Pezothrips kellyanus, and chewing citrus leafminer Phyllocnistis citrella and lemon butterfly Papilio demoleus. These pests are distributed across various regions of different continents such as in Asia-pacific, Americas, Africa, and Oceana. We presented detailed data from these pests’ biology, ecology, damage, and methods for control. The pest incidence and biology is affected by various biotic and abiotic factors thus providing the opportunity to use these factors as method of intervention to disturb pest life cycle. In this context, several IPM techniques such as cultural, physical, biological, and chemical methods were elaborated, which could help to reduce the pest status below damaging levels.
