AbstractIn. the spring of I97I, Neoaplectana bibionis Bovien was re-isolated from larvae and pupae of Bibio hortulanus L. and other bibionids from 3 localities in Denmark. Third stage infective larvae were recovered and used to initiate laboratory cultures. When nematodes were injected into the mouth of the greater wax moth larvae, Galleria mellonella L., they quickly penetrated into the hemocoel of the living insects and brought about their death. Successive nematode generations also occurred on artificial media used for rearing Neoaplectana carpocapsae Weiser. A specific rod-shaped bacterium was isolated from the intestine of infective stage larvae and probably has the same relationship to the nematode as N. carpocapsae has to its symbiotic bacterium, Achromobacter nematophilus. This nematode may make an excellent candidate for biological control programs involving soil insects.

Greenhouse Tests

In a series of greenhouse tests to determine the susceptibility of the larval stage of the curculionid Diaprepes abbreviatus to the entomogenous nematode Neoaplectana carpocapsae, the nematodes controlled the insect larvae. Grubs 1.5 to 3 months old (smaller than one inch long) were less vulnerable to death than older 3- to 4-month-old grubs. The highest grub mortality, 86.66%, was obtained with the nematode density of 40,000 nematodes per pot. When nematode density was increased from 40,000 to 400,000 nematodes per pot grub mortality did not increase. Grubs placed in direct contact with nematodes in petri plates were equally killed, independently of the nematode density used. Direct nematode inoculation through grub's mouth, anus or a combination of mouth and anus or steeped in water containing nematodes did not increase grub mortality beyond that already obtained in the soil. If similar results are obtained in the field, this method of control could be of great value to reduce D. abbreviatus populations.

The entomogenous nematodes Steinernema feltiae Filipjev ( = Neoaplectana carpocapsae Weiser), S. glaseri Steiner, and S. bibionis Bobien (Steinernematidae: Rhabditida) were evaluated as biological control agents against the banana root borer weevil Cosmopolites sordidus. In the grub stage this weevil bore tunnels in the corms of plantains thereby promoting infection and plant decay. In petri-dish trials the three species produced severe mortality at population densities of 4,000 and 40,000 nematodes. Similarly, in greenhouse tests, the three nematode species at rates of 400, 4,000, and 40,000 nematodes/4-month-old plants apparently reduced the number of tunnels produced by the grub. Grub mortality was 100% at nematode populations of 4,000 and 40,000 per plant.

Neoaplectana Carpocapsae Weiser

A survey was conducted to determine the presence of entomogenous nematodes which might parasitize Diaprepes abbreviatus (L.) larvae in Puerto Rican soils. One larva (2.3%) was parasitized with Heterorhabditis sp. Poinar when 4-month-old larvae were placed in the soil at eight different sites throughout the Island. Soil samples, taken from sugarcane fields and pasture lands in five geographical regions during July and September 1980, and January and April 1981, and inoculated with D. abbreviatus larvae did not reveal entomogenous nematodes. In the laboratory, when Neoaplectana carpocapsae Weiser was introduced into sterile soil from these regions, 40% of the exposed D. abbreviatus larvae became infected. We believe this is the first report of the entomogenous nematode, Heterorhabditis sp., occurring in Puerto Rico.
