...There are methods to spray insecticides so that they come directly on the insects, or to let insecticides with high penetrability penetrate the plant through the stems, leaves, or roots, and have the aphids absorb the plant juices. Predatory natural enemies such as ladybugs and parasitic natural enemies such as Aphidiidae (parasitic wasps specific to aphids, related to braconid wasps) also play a major role in controlling aphid populations. Other countermeasures include using crop varieties that are highly resistant to aphids, and taking advantage of the habits and physiological characteristics of aphids, and research is also being conducted on integrated control that combines these various methods. *Some of the terminology that mentions "Aphidiidae" is listed below.
