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.
Similar results have been obtained by several authors who have studied the effect of nutrient factors in diapause induction in stem borers.
Some planters do not realise the disastrous effects which follow when cane-tops infested with borers are planted.
It should be an invaluable addition to the library shelf for all those with a professional interest in stem borer pest management.
The number of surviving larvae+pupae recovered and the length of stalk bored were used as measures of borer numbers and stalk damage, respectively.
