Termites are well - known for their capacity to damage and destroy wood products of all kinds in the tropics and subtropics. A field test was undertaken to evaluate variations in wood consumption of Pinus sp. And three species of Eucalyptus by subterranean termites. The test consisted of wooden stakes of each species being initially submitted to water immersion for 0, 24, 48 and 72h, and buried in the ground to natural infestation by subterranean termites for an exposure period of 30, 45 and 60 days. Three species of subterranean termites were identified: Heterotermes longiceps (Snyder), Coptotermes gestroi (Wasmann) (Isoptera: Rhinotermitidae), and Nasutitermes jarague (Holmgren) (Isopetra: Termitidae). This is the first record of occurrence of H. longiceps in the state of Rio de Janeiro. Although the wood-consumption rates were not correlated significantly with their wood densities, there was a tendency of the softwoods (E. robusta and Pinus sp.) to be more consumed by subterranean termites than the woods of intermediate hardness (E. pellita and E. urophylla). Among the eucalyptus, E. robusta showed to be more susceptible to attack by subterranean termites tahn E. pellita and E. urophylla. Térmitas são bem conhecidas por sua capacidade de danificar e destruir madeira e produtos derivados nos trópicos e subtrópicos. Um teste de campo foi realizado para avaliar as diferenças no consumo de madeira de Pinus sp. e de três espécies de Eucaliptus por térmitas subterrâneos. O teste consistiu de estacas de madeira de cada espécie, que foram inicialmente submetidas à imersão em água por 0, 24, 48 e 72 horas, e enterradas no solo para infestação natural por térmitas subterrâneos por um período de 30, 45 e 60 dias. Três espécies de térmitas subterrâneos foram identificadas: Heterotermes longiceps (Syder), Coptotermes gestroi (Wasmann) (Isoptera: Rhinotermitidae), e Nasutitermes jaraguae (Holmgren) (Isoptera: Termitidae). Este é o primeiro registro da ocorrência de H. longiceps no estado do Rio de Janeiro. Embora a taxa de consumo de madeira não se correlacionou significativamente com a densidade da madeira, houve uma tendência das madeiras macias (E. robusta e Pinus sp.) serem mais consumidas do que as madeiras duras (E. pellita e E. urophylla). Entre os eucaliptos, E. robusta mostrou ser mais susceptível ao ataque de térmitas subterrâneos do que E. urophylla.

This study aimed to quantify the levels of resistance of 39 hybrids BClone 83 × Clone 02^of Coffea canephora var. conilon to the races II (v5) and XXXIII (v5,7,9) of H. vastatrix. To study the resistance of the genotypes, leaf discs were removed from the plants and spreaded on the top of a stainless steel screen inside gerbox as a moist chamber. The gerboxes were mantained at 22 ± 2 °C in the dark for 48 h and under 12 h of photoperiod, respectively. The hybrids were classified into four levels: resistant (R), moderately resistant (MR), moderately susceptible (MS) and susceptible (S). Leaf discs (%) containing sporulated lesions was the resistance component that had the greatest absolute correlation (0.95). The level of resistance of the hybrids varyied according to the race of the pathogen. The percentage of R, MR, MS and S of the hybrids to race II and XXXIII were 25 %, 25 %, 38 %, and 11 %, and 13 %, 37 %, 42 %, and 8 %, respectively. Nine (25 %) and five (13 %) hybrids were R to race II and XXXIII, respectively. Four hybrids (21, 30, 48 and 66) showed vertical resistance to races II and XXXIII. Possibly these hybrids have the resistance factor SH6, because they were resistant to race XXXIII v5,7,9. Leaf discs (%) with sporulating lesions can be used as a reference in future studyies of screening genotypes with horizontal resistance to C. canephora genotypes to leaf rust. |
