garden pests such as gypsy moths, Japanese beetles, sawflies, and peach twig borers
pests such as caterpillars, tomato hornworms, aphids, bean beetles, and various borers
The results showed that the remaining lepidopteran stem borer families and subfamilies have restricted host plant ranges.
For these pest groups, climatic conditions and geographical distribution of pests (downy mildews, corn borers, etc.) restrict the importance to some hot spots.
To enable measuring the effect of reduced borer densities on maize yield, the maize monocrop and all intercrops were grown with and without insecticide treatment.
Top borers attack the youngest part of the plant top, and usually destroy the growing point.
