The Science Behind Pest Control – An In-Depth Analysis

Due to DDT’s success, there was widespread optimism within entomology following its launch. But its failure to control all pests effectively, emergent resistant populations, rapid resurgence of secondary species (some previously innocuous), residues and persistent chemicals’ detrimental impacts on nontarget organisms and pollution have altered entomologists’ perspectives, with pest management now often emphasizing efforts that minimize or avoid chemical use as much as possible.

Ideally, biological control should be the first choice when controlling pests on crops; however, this is often not feasible due to invertebrate natural enemies being far less numerous than pests – making biological control an expensive proposition. Furthermore, many natural enemies are highly vulnerable to the same types of chemical pesticides used on them as with crops.

Insects are susceptible to diseases that can reduce their rate of feeding and growth, affect reproduction or kill them altogether. Parasitics are capable of invading pest cells to interfere with vital processes like digestion or excretion while fungi and protozoans can attack insects at different life stages.

Biological control requires extensive research on both the target pest and potential natural enemies, and careful collection, quarantining and release in an area where both enemies can encounter each other at times when their life cycles align with one another. Furthermore, physical selectivity ensures that an increased proportion of people are available at any given moment to attack any possible pest attacks that arise – it also increases chances of success with biological control methods.

Selecting appropriate natural enemies can be made easier through biological control agents that are more selective than traditional pesticides, such as predatory mites, parasitoids and viruses. Chemical pesticides may be reduced through using pheromone traps designed specifically to capture fruit flies; similarly pheromones may disrupt or confuse insect behavior and therefore protect insects from being killed off with chemicals.

Without effective nontoxic control methods available to them, some growers utilize natural enemies as a limited form of control. Most often these natural enemies target diseases; but other predatory organisms could include parasitoids and predators as well. Such programs typically utilize imported, exotic natural enemies instead of local species for control purposes. Temecula Pest Control Natural enemies often differ in habitat requirements from their target crop and there may be concerns regarding introducing native species into agricultural environments. However, these strategies can be costly and are generally restricted to crops with higher profit margins; the high costs of pheromones have kept many small farmers away from utilizing this strategy. Future agricultural success requires developing cost-effective, environmentally sustainable biological controls for crops of all sizes. To do so successfully requires collaboration among entomologists, pathologists, pollination ecologists and others who specialize in pollination ecology – their combined expertise must help delineate roles of each class of natural enemies they encounter as well as interactions among them and any pests or diseases they might prey upon or even exposure to pesticides or harmful elements in their environments.
