Control Japanese beetles, Popillia japonica with three different beneficial entomopathogenic nematodes in fall
The Japanese beetle (Popillia japonica) is one most damaging pests of turfgrass and ornamental plants grown in urban landscapes (Fig. 1 and 2) and golf courses where chemical pesticides are not currently recommended to use for controlling this important insect pest because of their deleterious effects on the human beings, animals and environment. It has been demonstrated that the beneficial entomopathogenic nematodes as biological control agents have a potential to control Japanese beetles.
The best time for the application of beneficial nematodes against Japanese beetle is during the late summer (August) to early fall (September-October) because beneficial nematodes will kill the Japanese beetle grubs/larvae before they move deep into the soil for overwintering. Thus, this targeted preventive application of beneficial nematodes should reduce the emergence of Japanese beetle adults during the next spring.
Following three beneficial entomopathogenic nematode species when applied at the rate of 1 billion nematodes per acre (which is equivalent to 23000 nematodes per square foot area) have been proved to be effective in infecting and killing grubs and pupae of Japanese beetles.
- Heterorhabditis bacteriophora nematodes
- Heterorhabditis indica nematodes
- Steinernema carpocapsae nematodes

Mnyama wa Japani (Popillia japonica) ni wadudu wa kuharibu zaidi wa nyasi na mimea ya mapambo inayokua katika mandhari ya mijini. "Kama ilivyoelezwa hapo juu, ""kiwanda cha dawa za kuua wadudu ni mojawapo ya njia za kuzuia wadudu wa hatari kwa binadamu, wanyama na mazingira.""" Imeonyeshwa kwamba nematodes zenye faida za entomopathogenic kama mawakala wa udhibiti wa kibiolojia zina uwezo wa kudhibiti vipepeo wa Kijapani. Wakati bora wa kutumia nematodes nzuri dhidi ya beetle ya Kijapani ni wakati wa majira ya joto (Agosti) hadi vuli ya mapema (Septemba-Oktoba) kwa sababu nematodes nzuri itaua larvae ya beetle ya Kijapani kabla ya kuhamia ndani ya udongo kwa ajili ya overwintering. Kwa hivyo, matumizi haya ya kuzuia yenye lengo ya nematodes zenye manufaa yanapaswa kupunguza kuibuka kwa watu wazima wa beetle ya Kijapani wakati wa spring ijayo. Aina tatu za nematode za entomopathogenic zinatumiwa kwa kiwango cha nematodes bilioni 1 kwa ekari (ambayo ni sawa na nematodes 23,000 kwa eneo la futi za mraba) na zimeonyeshwa kuwa na ufanisi katika kuambukiza na kuua magugu na pupae ya vimelea vya Kijapani. Heteroptera (Heteroptera) na nematodes (Heteroptera) ni aina ya nematodes ya aina ya Heteroptera, ambayo huathiri wanyama wa asili na wanyama wa asili. - Anita S.
