Pest management is an important component of crop production. Pests can have a detrimental effect on horticultural operations by affecting the quantity, quality and ultimately, the marketability, of the crops grown. A pest is any animal, insect, weed or disease that attacks a crop.
How does pesticide use affect agriculture?
In addition to posing risks to humans and to nontarget organisms outside of agroecosystems, heavy use of insecticides and other pesticides incurs significant direct and indirect costs to agricultural producers. Frequent applications of an insecticide can limit its effective lifespan as the target pest population develops resistance to that chemical. At the same time, the broad spectrum of activity of many pesticides leads to the creation of new pests by killing beneficial insects and other organisms that would normally regulate pest populations. Pesticide exposure can be lethal to honeybees and other pollinators that are necessary for the production of all fruit and most vegetable crops. Finally, as most conventional pesticides must be applied externally to the plants (although some are systemic), pesticides may not be effective under certain circumstances (e.g., when weather conditions prevent applications or when pests feed inside plant tissue).
Why are moths considered crop pests?
As noted earlier, many are migrants, preadapted to be crop pests (because they are highly dispersive insects that locate resources quickly and thrive in early successional habitats).
What is IPM in agriculture?
IPM is a sustainable approach to managing pests by combining different tools and strategies including pesticides, natural enemies, cultural practices, and host–plant resistance in a way that minimizes both economic and environmental risks. The approach is generally knowledge-intensive rather than product-intensive and strives to preserve and enhance natural controls of pests. Although most IPM programs in specific crops involve pesticide applications, the pesticides chosen tend to be fairly specific in their activity and pose less risk to humans and other nontarget organisms than other pesticides. IPM approaches also often include modifications to pesticide application practices to reduce human and environmental exposure.
Why is natural pest control important?
This focus is because promoting natural pest control could yield several important benefits, i.e., a reduced reliance on pesticide use, but also greater crop yields and increased biodiversity in agricultural landscapes ( Gagic et al., 2017 ).
What are the pests that humans have been able to control?
Humans have been managing agricultural pests for thousands of years. Pests can include weeds, plant pathogens (certain fungi, bacteria, and viruses), rod ents, and nematodes in addition to the plant-feeding insects and mites described in the preceding text, and are estimated to destroy as much as one-third of all agricultural yield. A wide array of pest control tools exist including cultural practices such as weeding, pesticide applications, and selective plant breeding for pest resistance.
How do abiotic factors affect insect pests?
Environmental favorability is influenced by abiotic factors that can affect a potential insect pest either directly via tolerance of physical, chemical, or climatic conditions, or indirectly through their influence on the nutritional quality of cultivated plants. For example, heavy rains not only lead to direct mortality of plant-feeding insects, but can also lead to improved host plant quality through the stimulation of plant growth. Similarly, environmental favorability is influenced by biotic factors that, in addition to host plant quality, include host plant abundance, activity of competitors and natural enemies, and disturbance from human intervention. Given the broad range of factors that contribute to environmental favorability, what evidence do we have that natural biological control ever plays a pivotal role in the suppression of potential agricultural pests?

How do worms damage apple trees?
The apple tree is mostly damaged by a worm which appears in spring and eats the leaves and spins a web. As a result [the fruit] is weakened and falls; it is especially more [abundant] in humid years. In some regions it is more prevalent. As this pest is [found] more in Isfahan and the tree is grown more in this city, its behavior is better known, [since] it has been more investigated. The method of control is as follows: when the worm appears for the first time, a wooden ladder is used to clean up the tree of worms [and their] webs, using an old piece of cotton which is rubbed on the stems [twigs]. If every day they clean up a few trees, the worm will not grow to eat the leaves and damage the trees. This method is not practiced in any other provinces; as the pest occurs, it is left undisturbed until the fruit is totally destroyed.

Pests and diseases that affect annual forages vary worldwide. Local recommendations are usually available for their control. Toxic chemicals are often used for control, and extreme care is required in their use. The chemicals have withholding periods when the animals should not be allowed to graze the sprayed crop. These periods should be adhered to carefully to reduce risks.
What are the pests that affect potato crops?
Insect pests account for 16% of the crop losses of potato (Solanum tuberosum L.) worldwide ( Oerke et al. 1994 ), and reductions in tuber yield and quality can be between 30% and 70% for various insect pests ( Raman and Radcliffe 1992 ). Among those pests are three species of the Gelechiidae (Lepidoptera) family, and these make up the so-called potato tuber moth complex, which are the common potato tuber moth, Phthorimaea operculella (Zeller), the Andean potato tuber moth, Symmetrischema tangolias (Gyen), and the Guatemalan potato tuber moth, Tecia solanivora Povolny. Although the three species have quite similar appearance and biology at first glance, there are differences among the species’ worldwide and regional distribution. This chapter describes the biology and ecology of the three species, and analyzes factors that favor or limit the different species’ distribution and damage potential.
What is insect pest management?
Insect pest management is applied insect ecology. Chapters 1 and 2 cover insect habitats, the influences of regulations and business practices, and methods for identifying and working with insects. Chapters 3, 4, and 5 emphasize the spatial aspects and Chapters 6 and 7 the temporal aspects of stored-product insect ecology. Decision aids ( Chapter 8) include sampling information, cost-benefit analysis, consultants, expert systems, and the predictions of computer simulation models. The economics of insect pest management ( Chapter 9) are important when using cost-benefit analysis. Resistance management ( Chapter 10) is necessary because insect populations readily adapt and are likely to eventually become resistant to any pest management method.
What insects feed on fruit?
Insect pests that feed internally in fruit are more difficult to detect and to disinfest, and are thus of greater concern in quarantine efforts. This type of feeding is most highly evolved and successful in several groups of the Lepidoptera, Diptera and Coleoptera, wherein the adult stage locates the host upon which the larval stage feeds and develops. Larvae enter fruit in one of two ways. In the Lepidoptera, for example, the eggs are placed by adults on or in the vicinity of the fruit, and the first larval stage penetrates the fruit after hatching. In contrast, for internal fruit feeding Coleoptera and Diptera, the adults choose and penetrate fruits using specialized ovipositors or mouthparts which allow them to place eggs directly in fruit tissues.
Which pathway has shown the most potential in insect pest control?
Among them, the siRNA pathway has shown the most potential in insect pest control. Briefly, when exogenous dsRNA designed to target an endogenous gene is delivered to the target pest, it triggers the slicing activity of Dicer, resulting in the long dsRNA being processed into short 21–22 nt siRNAs.
