Mean duration of nymphal period ([+ or -]SE), survival percentile ([+ or -]SE) and percentile of fertile females ([+ or -]SE) of Doru luteipes kept on four diets (26 [+ or -] 2[degrees]C, RH = 50 [+ or -] 10%; photophase = 12 hours).
Heat-shocked seedlings with psyllid eggs were immediately transferred to a rearing room under climate-controlled conditions (28 [degrees]C [+ or -] 2 [degrees]C; 60% [+ or -] 10% RH; 14-h photophase) for egg hatching and nymph development.
Table 1--Nutrient indices (mean [+ or -] SEM) of caterpillars in the 4th instar of Helicoverpa armigera under the diet regime, in the laboratory (25 [+ or -] 2[degrees]C, 60 [+ or -] 10% RH and 12 hours of photophase).
Cadavers were transferred to Petri dishes containing wet cotton (humid chamber) and placed in a BOD germination chamber (25 [+ or -] 1[degrees]C and 12 hour photophase) for 10 days to confirm the mortality caused by the pathogen through mycelial growth and fungus colonization.
Locomotor activity was measured as the number of movement events (ME) of the spider in the arena during the scotophase and photophase. The criterion for movement was a position shift not less than the body length of the spider.
The inoculated rice seedlings were placed in a chamber with a 12-24 h photophase under 25[degrees] C and then transferred to a greenhouse with 14 h of light and 10 h of dark for 7 days.
These containers were covered and maintained in a climate-controlled room (temperature 27 [+ or -] 2[degrees]C, 70 [+ or -] 10% relative humidity (RH) and 12 hours photophase).
zeamais with 10 to 14 days of age, arranged in each replicate and maintained in a BOD (Biochemical oxygen demand) chamber, at temperature of 25 [+ or -] 3[degrees]C, humidity of 70 [+ or -] 10% and photophase of 12 h.
The bees were maintained in a climate controlled chamber at 26 [+ or -] 1[degrees]C, and 70 [+ or -] 10% RH and 12-h photophase. The experiments were conducted in a completely randomized design, with 10 replicates per diet represented by the cages.
Temp: 25.2 [+ or -] 1.4[degrees]C, RH: 67 [+ or -] 0.7% and 12 h photophase. Treatment Eggs ([+ or -] SE) (2) Hatched ([+ or -] SE) (2) (n= 3) (1) Control 1604.8 [+ or -] 235.63 (a) 97.2 [+ or -] 0.37 (a) Clove 50 mg/L 790.4 [+ or -] 113.14 (b) 87.4 [+ or -] 1.43 (b) Statistics (P) [13.38.sup.0.0001] [24.38.sup.0.0001] (1) N = replication numbers.
The eggs were placed in petri dishes (2 cm high x 5 cm in diameter) lined with moistened filter paper and kept in a climatic chamber at 25 [+ or -] 2[degrees]C, with 70 [+ or -] 10% relative humidity (RH) and a 14 h photophase. The filter paper was moistened daily, and embryonic development was observed up to stage 4(S4), close to hatching, which was used on the experiments.
At the start of this 5-week regimen, temperature varied daily from 170[degrees]C to 8.0[degrees]C and the photophase was 16.5 h; at its end, in mid-September, temperature varied daily from 13.0[degrees] C to 2.5[degrees] C and the photophase was 13.3 h.
