Chrysopa oculata



     The Chrysopa oculata survives mostly on a diet of sugar, water, and pea aphids (Tauber and Tauber 1973).  Pea aphids are small bugs that can severely damage crops, such as peas and alfalfa (Integrated pest management North Carolina 2012).  Because of this, Chrysopa oculata are often used as biological control agents to keep these aphids from completely destroying certain gardens and harvests (Dunn 1996). When mating season arrives the females must prey completely on pea aphids to produce fertile eggs, while the males do not need this source of food for reproduction (Tauber and Tauber 1973).  Current research shows that certain chemicals, such as iridodial, can be used to draw Chrysopa oculata to a particular field or area to lay their eggs.  This would allow the newly hatched, predacious goldeneyed lacewings to consume large amounts of other pests, such as aphids.  This is a new technology in targeting certain areas for specific biological pest control (Chauhan et al. 2007).
