Resistant Genotypes

The preimaginal development of the parasitoid Cotesia marginiventris (Cresson) was observed in soybean looper, Pseudoplusia includens Walker, on different genotypes of soybean, Glycine max (L.) Merrill. Larvae were reared from eclosion on resistant soybean breeding lines, ED73-371 and D75-10230, both having PI 229358 as the resistance source, or on susceptible cultivars, ‘Bragg’ and ‘Braxton.’ Parasitized larvae consumed less foliage than nonparasitized larvae. Parasitized larvae, regardless of soybean genotype, also weighed less than nonparasitized larvae that fed on susceptible varieties. The developmental time of C. marginventris intrahost was not affected by the hosts' feeding on resistant germplasm. In field cages which contained only one of the soybean genotypes (no choice), parasitization of soybean looper among soybean genotypes was significantly greater in loopers collected from resistant genotypes for one generation during 1986. The resistant genotypes also had greater percentages of undeveloped parasitoids.

The seasonal incidence of Meteorus autographae Muesebeck (Hymenoptera: Braconidae) on larvae of the soybean looper, Pseudoplusia includens (Walker) (Lepidoptera: Noctuidae), in soybean fields in South Carolina was monitored at two locations during 1981, 1982, and 1983. In most instances, parasitism of soybean looper larvae by M. autographae was detected 7 to 14 days after soybean looper larvae were first found in the fields. During this three-year study, maximum parasitism of soybean looper larvae by M. autographae within a season ranged from 4.6 to 19.8%. In the laboratory, numbers of hosts parasitized per 24 hours by M. autographae increased with each successive increase in host density. At a host density of 40 larvae per 1.75-liter cylindrical container, an average of 26 hosts were parasitized by one M. autographae during 24 hours. Percent parasitism remained about the same (64 – 70%) at all host densities.
