Earthworm abundance and species diversity was evaluated in four land use systems near Jaguapitã, (Paraná); where pastures are being converted to soybean and sugarcane. Samples were taken during the rainy and dry seasons of 2004 and 2005 in eight sites: two old degraded pastures, an old pasture being converted to row cropping, two grain crop fields, two sugarcane fields and a native forest fragment. Twentyfive 25 × 25 cm soil blocks were taken at each site, 20 of them to 10 cm and five to 30 cm depth. Earthworms were manually sorted from the soil and preserved in formaldehyde. Earthworm species found were: the exotics Pontoscolex corethrurus (Glossoscolecidae), Dichogaster affinis, D. bolaui and D. saliens (Acanthodrilidae), Eukerria saltensis, E. eiseniana and Ocnerodrilus occidentalis (Ocnerodrilidae), and Amynthas sp. (Megascolecidae); the native species Glossoscolex n. sp. and Fimoscolex n. sp. (Glossoscolecidae), Belladrilus n. sp.1 and an unidentifiable Ocnerodrilidae n. sp.1 (probably Belladrilus); and two unidentified Eukerria spp. (of unknown origin) (Ocnerodrilidae)

The effect of the cultivars Miura (standard) and Korin, and the hybrids SM 14, SM 63, SK 1, SK 4 and FM 86 was evaluated on silkworm development, and on cocoon production and quality, at the Instituto Agronômico do Paraná, IAPAR, in Londrina, PR, Brazil (23 +/- 3 degrees C; 61 +/- 8% RH). The experiment was arranged in a randomized block design with four replicates. Larvae feeding either on 'SK 4' or on 'Korin' showed a higher weight compared to that of larvae feeding on 'Miura'. Cocoon weight (both sexes) and pupae weight (male) obtained with larvae fed on SK 4 were higher compared with that of insects that fed on Miura; there was no difference among the remaining treatments. Silk net weight was independent of the cultivar used. Cocoon shell weight was similar amon...

This study investigated the effects of seed dressing pesticides on survival and reproduction of Folsomia candida (Collembola), using standardized ecotoxicological tests (after ISO guidelines with few adaptations for tropical conditions). Commercial formulations of five seed dressing pesticides were tested individually in Tropical Artificial Soil (TAS): the insecticides imidacloprid, fipronil, thiametoxam, and the fungicides captan and carboxin+thiram. Thiametoxam, captan, and carboxin+thiram were only lethal to F. candida at the highest concentration tested (1000mg of active ingredient kg(-1) of dry soil). Imidacloprid and fipronil were lethal at lower concentrations (100 and 10mg a.i. kg(-1) soil d.w, respectively), however, these concentrations were much higher than those predicted (PEC) for soil. Imidacloprid and fipronil were the most toxic pesticides in both tests, reducing significantly collembolan reproduction (EC20=0.02 and 0.12mga.i.kg(-1) soil d.w, respectively). Further studies under more realistic conditions are needed, since imidacloprid and fipronil reduced collembolan reproduction at concentrations below or close to their respective PECs.

Smith) (Lepidoptera: Noctuidae). Neste trabalho, avaliou-se o efeito de temperaturas constantes no desenvolvimento de Doru luteipes (Scudder) e Doru lineare (Eschs.). D. luteipes não completou seu desenvolvimento nas temperaturas de 30 e 32ºC, enquanto D. lineare não completou apenas na temperatura de 32ºC. O período de incubação variou de 8,0 (25ºC) a 17,2 dias (18ºC) e de 4,6 (30ºC) a 14,5 dias (18ºC), para D. luteipes e D. lineare, respectivamente. A duração do período ninfal variou de 30,4 dias (25ºC) a 63,6 dias (18ºC), para D. luteipes, e de 20,4 dias (30ºC) a 60,5 dias (18ºC), para D. lineare. A duração do ciclo biológico (ovo-adulto) variou de 38,4 (25ºC) a 80,8 dias (18ºC), para D. luteipes, e de 25 (30ºC) a 75 dias (18ºC), para D. lineare. Portanto, as temperaturas elevadas foram desfavoráveis para ambas as espécies, observando-se que D. luteipes é mais susceptível à elevação térmica. ABSTRACT Some Earwigs species (Dermaptera: Forficulidae) are important predators of the fall armyworm, Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae). The effects of constant temperatures on the development of Doru luteipes (Scudder) and Doru lineare (Eschs.) were evaluated. The development of D. luteipes was not completed at 30 and 32ºC, whereas D. lineare did not complete only at 32ºC. The incubation period ranged from 8.0 (25 o C) to 17.2 days (18 o C) for D. luteipes and D. lineare, respectively. The duration of the nymphal stage ranged from 30.4 (25ºC) to 63.6 days (18ºC) for D. luteipes and, from 20.4 (30 o C) to 60.5 days (18ºC) for D. lineare. The duration of the biological cycle (egg-adult) varied from 38.4 (25 o C) to 80.8 days (18 o C) for D. luteipes and from 25 (30 o C) to 75 days (18 o C) for D. lineare. Therefore, high temperatures were unfavorable for both species, but D. luteipes is more susceptible to higher temperatures. 1567 Exigências térmicas de Doru lineare Eschs. e Doru luteipes Scudder em laboratório.

Earthworm communities were sampled in three areas with organic coffee cultivation (CO1, CO2 and CO3), two with conventional coffee (CC1 and CC2), and a native forest fragment (MT). The soil of the areas CO1, CC1, and MT was classifi ed as Nitossolo Vermelho (Rhodic Kandiudox), while CO2, CO3, and CC2 were on Latossolo Vermelho (Rhodic Hapludox). Eight samples were taken in each area on two occasions, winter and summer, using the Tropical Soil Biology and Fertility (TSBF) method in the 0-20 cm soil layer. The earthworms were handsorted and preserved in 4% formaldehyde, and were later weighed, counted and identifi ed. The highest earthworm biomass, both in winter and summer, occurred in the CO3 area. For population density, the higher numbers of individuals were found in CO1 and CO3. The highest number of species was identifi ed in the organic cultivation. The adoption of organic practices in coffee cultivation favored the diversity, density and biomass of earthworm communities.

The earthworms were collected in the municipalities of Barra do Bugres and Arenápolis, and were studied together with species previously identified from other municipalities. Seventeen municipalities, at 29 sampling points of Mato Grosso State, have been sampled. Seven species of earthworms were collected and identified in Barra do Bugres: Goiascolex vanzolinii, Pontoscolex (Pontoscolex) corethrurus, Opisthodrillus borellii borellii, Opisthodrillus sp., Dichogaster (Diplothecodrilus) gracilis, Dichogaster sp. and a species of the Criodrilidae family. Four species of earthworms were identified in Arenápolis: Pontoscolex (Pontoscolex) corethrurus, Dichogaster (Diplothecodrilus) gracilis, Dichogaster (Diplothecodrilus) affinis and Dichogaster sp. In total, 32 earthworm species/subspecies are known from Mato Grosso, 22 native and 10 exotic.

The first NT farmers created an association to promote their practices, the 'Clube da Minhoca' (Earthworm Club), thus named because of the observed increase in earthworm numbers in their fields after adopting NT. However, little data were available on the topic until 1996, when more intensive studies began near Londrina, in N Paraná. Earthworms were sampled by hand-sorting soil monoliths (25 × 25 cm square, 30-40 cm depth) at 8 sites, comprising various natural and agricultural land-use and management systems. Data from the literature were collected from a further 6 sites for comparative purposes. The results for N Paraná confirm the presence of higher earthworm populations under NT (46-116 indiv., 0.49-1.06 g f.wt. m -2 ; mean values in dry-wet seasons, respectively), minimum tillage (42-179 indiv., 0.68-1.05 g f.wt. m -2 ), pastures (48-182 indiv. m -2 ) and native forests (16-42 indiv., 1.56-0.83 g f.wt. m -2 ) than under conventional tillage (13-22 indiv. and 0.13-0.02 g f.wt. m -2 ). Soil disturbance thus had a negative impact on earthworm populations, and significant positive relationships were observed between earthworm abundance and age of NT systems, as well as with soil % C. In the Londrina area, some species present in the primary forests were absent in NT, where most earthworms were small-sized endogeic or epi-endogeic species. These results contrasted greatly with those from the cooler region in E Paraná, where the exotic epi-endogeic Amynthas spp. dominated, reaching high densities (up to >100 indiv. m -2 ) and biomass (up to >30 g f.wt. m -2 ), especially under NT. Given the high abundance of worms under NT, further work should focus on estimating their potential contributions to soil processes, fertility and plant production in these systems.

The eggs were collected on plants of P. hysterophorus. Rearing procedures, from egg hatching to aduld emergence, were carried out under controlled enviromental conditions: 25 ± 2ºC, 70 ± 10% UR and 12:12h of photoperiod. The egg stage lasted seven days; the larval development took 18.9 days, with 75% survivorship; the pupal stage lasted 6.1 days, with 65% of survivorship. C. lacinia saundersii prefered to feed on sunflower comparatively to P. hysterophorus. The weed plant, P. hysterophorus, can be considered a host-plant for the sunflower caterpillar.

The mulberry cultivars Miura (standard), Korin and Tailandesa and the hybrids FM 3/3, FM 86, SK 1 and SK 4 were tested. Seventy five fifth-instar commercial hybrid larvae were individualized in gerbox® unities and maintained in a rearing room (25 ± 3ºC and 80 ± 10% RH).The mulberry leaves of each of the five cultivars used to feed the silkworm larvae were submitted to bromatological analysis. The dry weight of larvae at the beginning and at the end of the fifth instar, the food consumed and the feces eliminated were recorded to determine the following indexes: relative consumption rate (RCR), relative metabolic rate (RMR), relative growth rate (RGR), approximate digestibility (AD), efficiency of conversion of ingested food (ECI), efficiency of conversion of digested food (ECD), metabolic cost (MC). The bromatological composition analysis of mulberry leaf cultivars revealed that the hybrid SK 4 presented superior nutritional quality compared to the standard cultivar Miura, due to its higher content in crude protein and ethereal extract, and lower detergent fiber content. The hybrid SK 4 was the most adequate food to the silkworm larvae because it was ingested in small amounts, thus providing good digestibility to the larvae, low metabolic cost, good growth rate and one of the highest efficiencies in the conversion of the ingested food and ingested and digested in biomass.
