Beneficial insects are a resource touse against insect pest in the garden (Mother Earth News, n.
d.). There are ways tomanage these insects and one of the ways is to follow the Intergraded PestManagement program (IPM, n.d.
). Within the IPM is aprevention step and this step can include attracting, buying, and raisingbeneficial insects (IPM, n.d.). Managing beneficialinsects is a healthier choice compared to chemical pesticides (Mother Earth News, n.d.). Beneficialinsects have three categories (Fugate, 2012).
The are pollinators,predators, and parasites (Fugate, 2012). Honeybees are anexample of the beneficial pollinator insects. An aphid eating ladybug is anexample of the beneficial predator insect (Fugate, 2012). The braconid waspthat injects her eggs under a hornworm skin is an example of a beneficial parasiteinsect (Gray, n.d.
). These insects bringbiodiversity to the garden (Mother Earth News, n.d.). Oneof the things that brings trouble to the beneficial insects is chemicalpesticides (Vinje, The Effect of Pesticides on Beneficial Insects, n.d.
). Chemical pesticidesnot only kill the pest, but also kills the beneficial insects, soil microbes,and nematodes (Vinje, The Effect of Pesticides on Beneficial Insects, n.d.
). Humans also havehealth risks when exposed to chemical pesticides (Lorenz, 2017). Chemical pesticidescan enter the body by skin, eyes, mouth, and lungs (Lorenz, 2017). Some of the symptomsare wheezing, coughing, difficulty breathing, coma, and death (Lorenz, 2017). There are differentchemical pesticides and cause different symptoms compared to others (Lorenz, 2017). One type of pesticidethat is a natural insect control that is made from soil-borne bacteria calledBt (Bacillus thuringinsis) (Vinje, n.d.
). This type ofpesticide is doesn’t harm humans, beneficial insects, or animals (Vinje, Bacillus thuringiensis Products, n.d.). A toxic crystalthat is in the spore of the bacteria disrupts the pest stomach and kills thepest (Vinje, Bacillus thuringiensis Products, n.d.).
There are different Bt sprays for different targeted insect pest (Vinje, Bacillus thuringiensis Products, n.d.).
TheIntegrated Pest Management consists of steps to follow and depending on whichyou use, will depend on the number of steps (IPM, n.d.). EnvironmentProtection Agency has four steps (IPM, n.d.
). The four steps are actionsthreshold, identify and monitor, prevention, and control (IPM, n.d.). Using IMP helpswith focusing on pest prevention and only uses pesticides as needed (IPM, n.d.). The IPM can be usedfor agriculture and non-agriculture (ex.
garden) (IPM, n.d.). Thereare three ways to bring beneficial insects into the garden. The ways arebuying, attracting, and raising.
Ordering online is an option to buying beneficialinsects. Arbico Organics has many beneficial insects to choose from and theygive instructions on how to care for and release (Beneficial Insects – Generalists, n.d.). Raising insects,for example ladybugs, need to have a net tent structure with holes where larvaeand adults can’t fit through (Saffell, n.d.).
The ladybugs wouldalso need enough flying space, food (ex. wheast), suitable temperature, andwater (Saffell, n.d.). The ways to attractbeneficial insects are with plants, fountain, and food like wheast (Hoffman, 2014) (Hadley, 2017). Plants not only attractthem, but also provide other food and shelter (Hoffman, 2014).
Usingchemical pesticides not only kills beneficial insects, but can cause majorsymptoms to humans or even death (Vinje, The Effect of Pesticides on Beneficial Insects, n.d.) (Lorenz, 2017). Bt spray is anotheralternative to chemical pesticides (Vinje, Bacillus thuringiensis Products, n.d.).IPM steps try to prevent the use of targeted or non-specific pesticides (IPM, n.d.
). Whether it is usinga combination or choosing just one of the ways to prevent insect pest, beneficialinsects bring biodiversity and are garden allies (Cedar Circle Farm, n.d.) (Mother Earth News, n.d.
