Tabulation and evaluation of recent field experiments using the DD-136 strain of Neoaplectana carpocapsae Weiser: a review

A tabulation and discussion of trials utilizing the nematode, Neoaplectana carposapsae Weiser, against insect pests in the field are presented. Only those references not included in an earlier review article (Poinar, 1971) are considered here.Moisture limits the immediate usefulness of these nematodes and this factor should be taken into consideration for field trials. The neoaplectanid species, N. carpocapsae, seems best adapated for living on or just beneath the soil surface but can also parasitize deeper soil insects and even enter plant tissue to locate successfully potential hosts.In conclusion, it can be stated that neoaplectanid nematodes can play an important role in the control of insect pest populations and may be most successful in a program of integrated control.
