We assessed the infestation of Bactrocera invadens Drew Tsuruta & White on field-collected Cavendish dwarf bananas of different ripening stages in Kenya and Mozambique. Of 5085 fruits collected in Kenya, B. invadens was reared from all ripening stages except bananas at the mature green stage. The highest level of fruit fly infestation was recorded from the 'all yellow' fruit ripening stage at 17% of which 401 B. invadens was recovered. In Mozambique, no fruit flies were recovered from a total of 169 fruits of different ripening stages sampled. Of 1349 culled Cavendish dwarf bananas sample, the highest number of fruit flies (518 B. invadens) was recovered from fruits that were precociously ripened. In field cage experiments conducted in Kenya and Mozambique, although oviposition wounds (101-587) were observed on green bananas after artificial infestation with 100-1000 gravid B. invadens females, no flies were recovered from fruits at the green stage of harvest maturity. Based on the results of these findings, mature green bananas of the Cavendish dwarf cultivar should be considered as a non-host stage of maturity for B. invadens. However, bunches with precociously ripened fingers and with other damages such as cracks and splits, ant burns, abrasions, point bruise, tip rot or general decay should be carefully inspected before export and discarded because such damages can permit attack by B. invadens and pose the risk of inadvertent translocation of the insect during export. © 2013 Blackwell Verlag GmbH.

Fresh fruits are increasingly focused in the recent years for their nutritional and health benefits. Research involving simple and safe preservation technologies is at a high demand to satisfy consumer concerns and harvest maximum market potential. The present study was therefore undertaken to assess the response of chemical and bioactive compounds (pH, acidity, ascorbic acid, total phenolics, carotenoids, free radical scavenging capacity and enzyme activity) in apricot under the effect of calcium treatments (1, 2, 3 and 4%) at ambient storage. The results revealed that ascorbic acid, phenolic compounds and carotenoids were least affected in 3 and 2% calcium as compared to control, 1 and 4% CaCl2. Similarly, higher antioxidant capacity and lower enzymatic activity was retained in the same concentrations. Titratable acidity and ascorbic acid decreased in all treatments during storage and higher reduction was observed in control, 1 and 4% as compared to 3 and 2% calcium, respectively. pH, phenolics, carotenoids, antioxidant and enzymatic activity increased initially and it was rapid up to 6th day, followed by a slight decrease during subsequent storage. The overall results demonstrated higher compositional losses in control followed by 1 and 4% calcium treated fruits, while 3 and 2% treatments exerted pronounced effects on keeping quality of apricot during ambient storage up to 12th day. © Asian Network for Scientific Information, 2013.

This study was accomplished to determine the effects of egg yolk, egg white and sodium carbonate on textural properties of beef patties by using Central Composite Design of Response Surface Methodology. Meat patties were prepared using beef, lamb tail fat and spices. Effects of addition of egg yolk powder (0-1%), egg white powder (0-1%) and sodium carbonate (0-1%) on textural properties were studied by using a texture analyzer. The TPA and cutting force tests were measured in the samples. Effects of sodium carbonate were found to be significant (P∈<∈0.01) on springiness, hardness and cohesiveness values of beef patties. However, effects of egg white and egg yolk on the textural parameters were not found significant (P∈>∈0.05). The levels of sodium carbonate up to 0.72% improved the textural properties of beef patties. © 2011 Association of Food Scientists & Technologists (India).

Twelve-year-old apricot trees from the 'Hacihaliloglu' apricot cultivar were pruned in a series of five treatments. In all treatments, one-third of annual shoots (33.3%) were removed between 1999 and 2003. The chlorophyll a, chlorophyll b, total chlorophyll and carotenoid contents in leaves were determined. The starch, total sugar, reducing sugar and sucrose contents in shoots were also determined. In addition, seasonal variation of carbohydrates was studied. The treatments did not affect the carotenoid content of leaves, but they statistically affected the total chlorophyll content. The highest total chlorophyll content in leaves was 5.27 mg/g, and it was found in the post-harvest summer/winter pruning treatment. The highest average total sugar content (6.25%) was observed in the post-harvest summer pruning treatment, while the lowest (2.56%) was found in the post-harvest summer/winter and control treatments. The highest starch content (8.18%) was found in October from the post-harvest summer/winter treatment, whereas the lowest value (3.59%) was obtained in March from the winter pruning treatment. Summer pruning treatments promoted an accumulation of carbohydrates.

This study was accomplished to determine the effects of sodium carbonate, egg yolk, and egg white powders on some of the physical-chemical and sensory properties of meat patties by using central composite design of response surface methodology. Meat patties were prepared using beef, lamb tail fat, and spices. Effects of the addition of egg yolk powder (0-1%), egg white powder (0-1%), and sodium carbonate (0-1%) on pH, proximate composition, cooking yield, and sensory properties were studied. The influence of egg yolk in the beef patties was found to be limited. However, the effects of egg white and sodium carbonate were found to be significant on several parameters. The levels of sodium carbonate up to 0.8% and egg white greater than 0.5% improved the physical-chemical and sensory properties of beef patties. © 2011 Berkeley Electronic Press.

Pink snow mold, caused by Microdochium nivale, is a serious disease of winter wheat (Triticum aestivum) in the Northern Hemisphere. A field study with artificial inoculation was conducted using 38 winter wheat cultivars during the 2002-2003 at Erzurum, Turkey. Significant differences were detected among cultivars for reaction and yield components to the M. nivale. The most resistant winter wheat cultivars were Harmankaya and Pehlivan, and the most susceptible ones were Aytin-97, Ki{dotless}rgi{dotless}z-95 and Bayraktar. Yield components decreased significantly in inoculated plants. Pink snow mold resulted in decreased number of spikes per m2, the grain yield and the plant height of 71.1, 67.3 and 13.2% respectively.

Lecanicillium muscarium (Petch) Zare et Gams is a widely occurring entomopathogenic fungus. The effect of L. muscarium against Ricania simulans (Walker) (Rhynchota Ricaniidae) was studied under laboratory and field conditions. In laboratory studies, six isolates of L. muscarium were assessed against nymphs of R. simulans, at a single dose (1 × 107 conidia/ml) on tea leaflets. Mortality percentage caused by L. muscarium isolates after a seven-day period varied from 50.95 to 74.76% and median lethal time (LT50) values ranged from 2.34 to 3.90 days. In a field experiment, L. muscarium strain Lm4 was assessed against nymphs and adults of R. simulans, at a single dose (1 × 107 conidia/ml) on kiwifruit plants. The LT50 values for nymphs and adults of R. simulans were 4.18 days and 6.49 days, respectively. The results of the field study indicated that R. simulans nymphs were more susceptible to the fungus than adults. L. muscarium strain Lm4 could be considered as an environmentally friendly alternative for biocontrol of R. simulans.

This study presents a low cost measurement setup for estimating apple bruise volume during drop impact tests. The proposed measurement system consists of three main stages namely recording impact sound, signal processing, and estimating bruise volume. In the recording stage, the impact sound occurred when striking the apple on the surface was recorded by a piezoelectric microphone into computer. The impact sound was converted into Shannon entropy signals based on the Kernel density approach, and two measurable quantities namely entropy peak and pulse-width time were extracted from Shannon entropy signals in the signal processing stage. In the bruise volume estimating stage, the regression curves that map entropy peak and pulse-width features into bruise volume are estimated using measurements data. To evaluate the performance of the proposed method, we conducted several drop experiments with six different drop heights and two different temperatures (1 and 19. °C). Experimental results showed that bruise volume was exponentially proportional to the entropy peak and it was inversely proportional to pulse-width time as power functions, and all the curves were fitted with coefficients of determination of more than 0.98. Moreover, it was found that colder apples developed less bruise volume then warmer ones. © 2014 Elsevier B.V.

The objective of this study was to determine the seroprevalence of paratuberculosis in dairy cattle in Burdur province located in southwest of Turkey. Blood samples were collected and tested by the enzyme linked immunosorbent assay (ELISA) from 465 dairy cattle older than 2 years randomly selected from 24 dairy cattle herds. Seroprevalence of paratuberculosis was found in 6.2% at the individual cow level and 58.3% at herd level. Seropositivity was detected in a total 14 of 24 herds. The prevalence of paratuberculosis by age ranged from 3.6% to 19.73% where the highest prevalence rate was found in 3 years olds. In conclusion, we determined that the seroprevalence of paratuberculosis in Burdur province was higher than those in other parts of Turkey. In addition, we found that when the size of the herd increased, the possibility of infection with paratuberculosis was greater.
