Diagnosis. Thaumastocoris safordi can be recognised by the following characters: slender body, costal margins subparallel (Figure 8 C,D); distinctive tubercle on anterolateral angle of pronotum (Figure 16 E); pygophoral lock basally invaginated; paramere apically recurved (Figure 19 E). It can be distinguished from T. slateri, which also has the distinctive tubercle on the pronotum, by the male genitalia (cf. Figure 19 F); the pygophoral lock of T. slateri is not invaginated basally but weakly flared; and the paramere of T. slateri is flat and not recurved apically as in T. safordi. Furthermore, these two species differ in their body shape: T safordi having a slender subparallel body shape and the abdomen of T. slateri is laterally expanded beyond the costal margins, which is visible from above (cf. Figure 9 A,B). In addition, T. safordi is smaller and more polished than T. slateri. Description. Submacropterous. Male length 2.41–2.65, width 0.71–0.77; female length 2.41–2.69, width 0.86–0.98.

Thaumastocoris safordi is known from eastern Australia, with a significant distributional disjunction between the Sydney Basin and southeast Queensland (Figure 21 B). Host plants. Thaumastocoris safordi has relatively broad host range and is known from three species of Corymbia, and a single species each of Eucalyptus and Acacia (Table 3). Thaumastocoris safordi was collected from much of the Sydney basin in small numbers on C. citriodora and C. maculata during a survey to ascertain the extent of T. peregrinus infestation in 2002 (Noack 2009). Concurrently, in south east Queensland, this species was heavily infesting plantations of C. variegata (Lawson et al 2010) (Figure 1 B). Remarks. Thaumastocoris safordi has increased in numbers since being first collected in 2002 (Noack 2009), and now many Corymbia spp. street trees planted in the Sydney basin are displaying the yellowish faded green colouration of infestation (AEN, personal observation). Noack and Rose (2007) have studied its life-history in the laboratory.Published as part of Noack, Ann E., Cassis, Gerasimos & Rose, Harley A., 2011, Systematic revision of Thaumastocoris Kirkaldy (Hemiptera: Heteroptera: Thaumastocoridae), pp. 1-60 in Zootaxa 3121 on pages 50-52, DOI: 10.5281/zenodo.27937

No full textThaumastocoris slateri Noack, Cassis & Rose n.sp. (Figures: 9 A,B; 17 A–H; 19 F) Etymology. This species is named in honour of the late Professor James A Slater, who has been one of the most significant heteropterists of all time, had a special interest in Australian true bugs, and published significant works on the Thaumastocoridae. Holotype: 3, QUEENSLAND: St Lucia, university of Queensland campus, nr city cat dock, 27.4938 S 153.0166 E, 10 July 2004, HA Rose, ex Corymbia variegata (AM).

Diagnosis. Thaumastocoris slateri can be distinguished by the following combination of characters: body large; eyes strongly pedicellate; anterolateral angle of pronotum with conspicuous tubercle; abdomen expanded beyond costal margins of hemelytra (Figure 9 A,B).

In addition, the pygophoral lock of T. slateri is elongate and weakly concave apically (Figure 19 F), whereas in T. safordi the lock is stout and strongly concave apically (cf. Figure 19 E). Further, the hemelytra of T. slateri are relatively short, not reaching the genital capsule, whereas the hemelytra of T. safordi cover almost the entire dorsum. Description. Submacropterous. Male length 3.08–3.20, width 0.98–1.05; female length 2.96–3.16, width 0.84–1.11. Females are darker in colouration, abdomen more expanded. Colouration.

Thoracic pleura and sterna: dorsoposterior area of propleuron with fine punctures submarginally; metapleural suture marked by single row of fine punctures (Figure 17 E); thoracic sterna impunctate, mesosternum strongly polished medially. Scutellum: densely and regularly punctate, punctures deep, midline polished posteriorly.

Thaumastocoris slateri is the largest species in the genus.Published as part of Noack, Ann E., Cassis, Gerasimos & Rose, Harley A., 2011, Systematic revision of Thaumastocoris Kirkaldy (Hemiptera: Heteroptera: Thaumastocoridae), pp. 1-60 in Zootaxa 3121 on pages 52-54, DOI: 10.5281/zenodo.27937
Coffee berry disease in Kenya
No full textData are presented on research in Kenya in 1964 - 1969 on anatomical, mycological, epidemiological, chemical control and cultural aspects of coffee berry disease, Colletotrichum coffeanum Noack, of Coffea arabica L. The pathogen causes flower and berry losses and was found in branches where it occupied clearly defined areas of the cortex just before or after formation of the first phellogen. Saprophytic Colletotrichum spp. inhabit bark areas with more periderms in the cortex. No relationship could be found in Kenya between Glomerella cingulata (Stonem.) Sp. & Schr., the perfect stage of most of the saprophytic Colletotrichum bark components, and C. coffeanum . The seasonal fluctuations in pathogenicity in the bark population of C. coffeanum could be assessed and compared with the total sporulating capacity of the bark population of all Colletotrichum spp. Formerly the level of this total sporulating capacity, or 'inoculum potential' as it was then called, was used as an indication when pre-rain copper sprays had to be applied and how effectively the fungicide had reduced the bark inoculum. Based on these data the recommendations for chemical control were changed from pre-rain fungicide applications, to a spraying regime well into the rainy period, the accent being on protection of the berries rather than on a reduction of the bark inoculum. The fungicide Ortho Difolatan proved to be more effective than copper based compounds. Cultural practices, like the application of high levels of fertilizers, manure and mulch and rigid pruning practices, had no effect on the level of C. coffeanum in branches. Copper containing fungicides pushed the Colletotrichum balance in favour of C. coffeanum . Berries from non-copper sprayed coffee fields were less susceptible to standard conidial suspensions of C. coffeanum than berries from copper sprayed trees. A similar effect of fungicides should be considered in South and Central American coffee growing countries, where the application of fungicides has increased tremendously since the occurrence of Hemileia vastatrix Berk. et Br. in Brazil
Generation of high-power femtosecond light pulses at 1 kHz in the mid-infrared spectral range between 3 and 12 mu m by second-order nonlinear processes in optical crystals
No full textWe review methods for frequency conversion of amplified femtosecond laser pulses from the near- to the mid-infrared. The potential of all commercially available optical crystals is evaluated on the basis of the specific requirements in the high-power femtosecond regime. A comparative experimental study of a number of materials (birefringent and quasi-phase-matched) employed in a seeded optical parametric amplifier pumped near 800 nm is presented, where the generated idler is tunable between 3 and 4 mum. Internal conversion efficiencies as high as 40% and pulse energies as high as 20 muJ are achieved in this spectral range. Wavelength tunability up to 12 mum with energies exceeding 1 muJ is demonstrated by pumping optical parametric amplifiers and generators near 1.25 and 2 mum, as well as by difference frequency generation with a quantum efficiency of 40-80%. In all cases the generated mid-infrared pulses are almost bandwidth limited with a duration of 100-200 f

Difference-frequency generation of intense femtosecond pulses in the mid-IR (4–12 μm) using HgGa2S4 and AgGaS2
No full textWe compare the properties and the performance of HgGa2S4 and AgGaS2 in a high-power difference-frequency generation scheme mixing the signal and idler from a travelling wave optical parametric generator at 1 kHz. Femtosecond pulses from 3.7 to 12 mum with quantum efficiency of 40-80% are generated with HgGa2S4 which is about 1.2 times higher than with AgGaS2 typically used in that wavelength range. The maximum single pulse energy obtained exceeds 9 muJ near 4 mum and 1 muJ in the whole tunability range which represents about an order of magnitude improvement in comparison with previous results. The mid-infrared pulses are almost bandwidth limited with durations of the order of 200 fs and less (minimum 165 fs). (C) 2000 Elsevier Science B.V. All rights reserve
