Title: Recent approaches for controlling downy mildew of cucumber under greenhouse conditions
Abstract: The efficacy of biocontrol agents (effective microorganisms (EMs1), Bacillus subtilus, and Bacillus pumilus), zinc oxide nanoparticles, castor and clove oils, as well as of a recommended fungicide (famoxadone + cymoxanil) utilised during two growing seasons under greenhouse conditions against downy mildew of cucumber were evaluated. Furthermore, GC-MS analysis was carried out to identify the bioactive chemical components of plant origin oils (castor and clove). The effect of these treatments on some biochemical, growth, and yield characters of cucumber was also investigated. Famoxadone + cymoxanil was the most effective treatment in both test seasons, followed by clove oil, zinc oxide, EMs1, Bacillus pumilus, Bacillus subtilus, and castor oil. The results showed a significant effect of all the treatments on some biochemical (chlorophyll content, peroxidase, and polyphenoloxidase) as well as growth and yield characters (plant height, fruit number per plant, and fruit yield) of the cucumber plants relative to control.

Title: Antifungal activities of Chaetomium spp. against Fusarium wilt of tea
Abstract: An isolate of Fusarium denominated as NHP-Fusa-2 from tea wilt and root-rot diseased sample collected in Vietnam was identified as Fusarium oxysporum based on molecular analysis of translation elongation factor-1α sequence. Interestingly, it is the first time F. oxysporum is reported as a causal pathogen of wilt and root-rot disease of tea in Vietnam. Chaetomium spp. were investigated to control F. oxysporum NHP-Fusa-2 in in vitro test. Three antagonists (Ch. cupreum CC3003, Ch. globosum CG05, and Ch. lucknowense CL01) inhibited mycelial growth by 31.69-34.03% and reduced conidial production of the pathogen by 67.25-75.92% in the bi-culture antagonistic test after 30 days with non-significant difference in their effect. All the crude extracts of these antagonists significantly inhibited mycelial growth and conidial production of NHP-Fusa-2. MeOH extract of CC3003 was more effective in conidial inhibition of the pathogen than the others, the effective dose (ED50) was 85.30 μg/ml of which, it was hexane (49.32 μg/ml) and EtOAc extract (62.17 μg/ml) in the case of CG05 and CL01, respectively.

Title: Comparison of two Coniochaeta species (C. ligniaria and C. malacotricha) with a new pathogen of black pine needles - Sordaria macrospora
Abstract: A new pathogen, Sordaria macrospora, isolated from damaged needles of black pine (Pinus nigra) causes discolouration, brown spots, blight symptoms, and necroses spoiling aesthetic value. Two species, C. ligniaria and C. malacotricha, the most common anamorphs attributed to Coniochaeta species occurring on selected conifers, and a new pathogen, Sordaria macrospora, occurring on Pinus nigra, are compared. Specific differences in spore size and anamorph morphology between the similar species C. malacotricha and C. ligniaria could be confirmed.

Title: Projections of climate-induced future range shifts among fruit fly (Diptera: Tephritidae) species in Uganda
Abstract: The potential impact of future climate change on fruit fly species distribution was assessed in Uganda using two general circulation models (HADCM and CCCMA) and two future predicted CO2 emission scenarios (A2 and B2), under both full and no species dispersal modes. Future ranges were overall projected to decline by 25.4% by year 2050. Under full-dispersal, D. ciliatus > C. cosyra > B. invadens ranges were predicted to increase, while the rest are likely to decrease. In the no-dispersal scenario, a significant average decrease in size of niches is predicted. Range losses are predicted higher under B2 than A2. Future niches will likely shift to northern Uganda. The results should assist in the development of climate change adaptive pest management strategies.

Title: Synergism of entomopathogenic fungus, Metarhizium anisopliae incorporated with fipronil against oil palm pest subterranean termite, Coptotermes curvignathus
Abstract: The compatibility and synergy in efficacy of the termiticide fipronil with a biocontrol agent Metarhizium anisopliae, alone or in combination, against the subterranean termite, Coptotermes curvignathus were investigated. Sublethal doses of fipronil were found relatively less detrimental to fungal growth of M. anisopliae local isolates in a compatibility test. The fungus-insecticide bait formulation showed the greatest synergistic effect that increased termite mortality as well as reduced the lethal time at a sublethal dose of 0.05 mg a.i./l fipronil with conidia concentrations of 107 conidia/g bait (χ2 = 48.80) at LT50 value of 6.46 days, followed by 108 conidia/gbait (χ2 = 5.09) at LT50 value of 4.89 days compared to the use of these control agents alone. The insecticidal stress caused by sublethal fipronil in the formulated bait may weaken the termites and reduce their defence mechanism, which facilitates fungus infection on termites. The observed synergism treatments show the potential for integrated fungus-insecticide control method and need to be further investigated on termite infested oil palm trees.

Title: Trapping of internal and external feeding stored grain beetle pests with two types of pitfall traps: a two-year field study
Abstract: Pitfall trapping studies are available for particular stored grain pest species. In small farms, the stored grain pest control strategy is rarely species-specific but is often "pest ecological-group-specific" instead. A two-year field study was conducted in flat grain stores to compare the efficacy of cone-surface (PC trap; AgriSense-BCS Ltd., Pontypridd, UK) and probe-subsurface (WB Probe II Trap; Trécé Inc., Adair, USA) traps for three ecological insect pest groups (Group I, internal feeding primary pests; Group II, external feeding primary pests; Group III, external feeding secondary pests). Altogether, 1328 specimens (32% Group I, 11% Group II, and 57% Group III) in 12 species of Coleoptera (17% Group I, 25% Group II, and 58% Group III) were trapped. No significant differences were found in the efficacy of PC traps and WB Probe II Traps to catch the evaluated ecological pest groups over the long term. Our study indicated that for trends to appear in long-term trapping there was no need for the simultaneous use of both traps due to the low trapping differences between the surface and subsurface types of traps in all ecological pest groups. However, significant differences between the traps were found in the short-term evaluations and before and after fumigation; in that case, the use of both traps is recommended because of the higher sensitivity and more precise evaluation of efficacy of the control treatment effects.

Title: Acaricidal properties of extracts of some medicinal and culinary plants against Tetranychus urticae Koch.
Abstract: The acaricidal activity of aqueous extracts obtained from 28 plant species was tested against Tetranychus urticae. The extract efficacy on the incidence of individual development stages of T. urticae on the treated plants was determined, compared to untreated plants. Of the 28 extracts, 24 showed an efficacy higher than 50%; of these, 16 extracts caused a reduction in the count of adults on the plants by more than 90% compared to the control. The counts of nymphs and eggs showed significant differences depending on the extract used. Only 13 extracts showed an efficacy higher than 50%, and only 2 extracts (obtained from Ammi visnaga and Saponaria officinalis) had more than 90% efficacy. Twenty extracts resulted in eggs reduction of more than 50% compared to the control; of these, 6 extracts (from A. visnaga, G. glabra, J. palmata, L. carthamoides, O. majorana, S. officinalis) exhibited an efficacy higher than 90%. Extracts with the highest efficacy were tested for their acute toxicity for T. urticae adults, and LD50(90) values were estimated. By comparing the confidence intervals (CI95) for individual LD50 values, extracts obtained from Saponaria officinalis roots and Ammi visnaga seeds were found to provide the significantly highest efficacies, and lethal doses (LD50) of 10.3 and 12.5 g/l, respectively, were estimated for them. However, wanting to compare LD90 values as well, we chose 5 extracts (A. visnaga, C. annum, M. × piperita, O. majorana, and S. officinalis) whose CI95 intervals overlapped (P ≤ 0.05). Based on our tests, aqueous extracts from S. officinalis roots can be recommended for the development of products which reduce the incidence of T. urticae on plants.

Title: Inhibiting effect of shallow seed burial on grass weed emergence
Abstract: The efficacy of superficial tillage as a sustainable tool to reduce the emergence of Digitaria sanguinalis, Setaria viridis, and Sorghum halepense was evaluated with field experiments. Seeds were buried at 1, 2, 5, and 10 cm of depth to simulate seed vertical distribution caused by autumn superficial tillage. Seedling emergence was monitored weekly for two years after sowing. The highest emergence was obtained in the first year after sowing and from 1 and 2 cm. Sorghum halepense was only slightly affected by seed burial, with 15% of emergence from 10 cm of depth, while D. sanguinalis was strongly affected, with 4% of emergence from 5 cm. The efficacy of superficial tillage as control tool could vary according to local weed flora.
