Pupae of Thyrinteina arnobia (Stoll) and Thyrinteina leucoceraea Rindge (Lepidoptera: Geometridae) were obtained from Eucalyptus cloeziana F. Muell and Eucalyptus urophylla S.T. Blake plants, respectively. Specimens of a parasitoid emerged from T. arnobia pupae and also found parasitising T. leucoceraea pupae in the field were identified as Palmistichus elaeisis Delvare and LaSalle (Hymenoptera: Eulophidae). This is the first report on P. elaeisis parasitizing T. arnobia and T. leucoceraea pupae in natural conditions in Brazil. P. elaeisis also parasitized these hosts and Bombyx mori Linnaeus (Lepidoptera: Bombycidae), Anticarsia gemmatalis Hubner, Pseudaletia sequax Franclemont, Alabama argillacea Huebner (Lepidoptera: Noctuidae), Dirphia moderata Bouvier (Lepidoptera: Saturniidae) and Halysidota pearsoni Watson (Lepidoptera: Arctiidae) in the laboratory. The production and release of P. elaeisis could be an efficient alternative for controlling Lepidoptera defoliators in eucalyptus plantations.

Abstract: The objective of this work was to evaluate spatial and temporal distributions of Sarsina violascens (Lepidoptera: Noctuidae: Lymantriinae) in two Eucalyptus cloeziana plantations, one with native vegetation strips (WNVS) and another without them (ONVS). Adults were collected with light traps, which were installed: inside an area of native vegetation (Cerrado), 100 m from the edge; at the contact zone between the native vegetation area and the E. cloeziana plantation; inside the E. cloeziana plantation, 250 m from the edge; at the central part of the native vegetation strip, around 500 m from the edge (WNVS) or in the contact zone between two E. cloeziana compartments (ONVS); and inside the E. cloeziana plantation, 500 m from the edge. The number of S. violascens adults collected was 240 in the system WNVS and 1,378 in the system ONVS. The lower number of individuals in the system WNVS was probably due to favored biological control provided by higher species richness with the use of native vegetation strips. These strips, intermingled with E. cloeziana plantations, allow a higher proportion of native forest in the landscape and can help to reduce S. violascens infestations.

Anticarsia gemmatalis nucleopolyhedrovirus (AgMNPV) is being used in Brazil as a biological insecticide. Host plant resistance of soybean to insects is been searched for and some authors have mentioned the interference of plant chemistry in virus efficiency. Interactions among soybean extracts of genotypes used as a source of resistance (PI 274454 and PI 227687) with different AgMNPV concentrations in populations of A. geatalis susceptible (S) and resistant (R) to the virus were studied at laboratory condition. Higher mortality was observed when larvae fed on diets with extracts of the soybean genotypes compared with those fed on a plain diet (control). The mean lethal concentration (LC50) was reduced about 10 ties in the S-population fed on diets containing PI 274454 extracts and different concentrations of AgMNPV, compared to control diet. Additive effect was predominantly observed when larvae fed on diets with extracts of soybean genotypes (PI 274454 and PI 227687) and AgMNPV for both larval populations. The pupal weight was negatively influenced by the extracts incorporated to the diets compared to control, for both larval populations, notably for R-population. The results suggest that, in general, leaf extracts of soybean resistant genotype did not cause any harmful effect on virus efficiency.
