However, its roots extend back to the year 1921. Today, it is an international scientific journal focused on all aspects of plant protection sciences, fully published in English. This occasion offers a fitting opportunity to describe some of the most important historical stages of the journal's development. In our brief historical overview, we summarise the changes in journal title, chief-editors, and editorial policy during the last fifty years, and with an examination of its importance, scope and readership. We present analyses of the journal's development, some for the entire period of 1965-2013, while others are limited to more recent decades. The journal's present place among the world's scientific journals is documented by analyses in the international citation databases, BIOSIS CI, SCOPUS, and WOS. An analysis of three particular citation databases were made in October 2013, while the overall period 1998-2013 was conducted from All Databases/Thomson Reuters in March 2014. PPS is also included in other, important technical-literature databases, including Czech Agricultural and Food Bibliography, AGRIS/FAO database, AGRICOLA, CAB Abstracts, Current Contents, and Zoological Abstracts. Information about all of them is available in Ulrich's WEB database. In the final part of this paper, we summarise some recent achievements of the journal, and discuss some key topics related to its future development.

The tested compounds exhibited variable degree of antibacterial activity against both tested bacteria as minimum inhibitory concentrations (MIC) ranged 90-520 mg/l. Neoambrosin showed the highest antibacterial activity among the tested sesquiterpenes with MIC values of 150 and 90 mg/l against A. tumefaciens and E. carotovora, respectively. On the contrary, hymenin was the least effective compound with MIC values of 520 and 310 mg/l against A. tumefaciens and E. carotovora, respectively. Neoambrosin, damsinic acid, and damsin caused significant reduction in sulfhydryl group content with the former being the most effective. The tested sesquiterpenes significantly inhibited polygalacturonase and pectin-lyase activities of A. tumefaciens and E. carotovora except for hymenin which caused a significant activation of E. carotovora enzymes.

Studies on the pathogen variability and distribution of races are essential to identify effective sources of resistance to this disease. In this study, a survey was conducted during the period 2007-2011 in four different agro-climatic zones. Pathogenic variability in 52 isolates of FOP, collected from different pea-growing areas of western Algeria, were evaluated using 7 genotypes as differential hosts. Results indicated that the disease was prevalent in all fields prospected and isolates obtained were assigned to Races 1, 2, 5 or 6 by their pathogenicity. It was found out that Races 1 and 2 were more common in all areas with 61.5 and 19.2%, respectively. This study is the first report of pea Fusarium wilt races distribution in Algeria.

Four types of fungi (Alternaria spp., Dendryphion penicillatum, Fusarium spp., and Penicillium spp.) were detected on poppy seeds, with the highest infection rate being 72% for D. penicillatum. Surface disinfection decreased infection rate chiefly in D. penicillatum (by 32%) and in Alternaria spp. (by 16%). Seed treatment increased emergence by 9-10% in laboratory experiments but by only 0-6% in greenhouse experiments. Temperature plays an important role in emergence. In climate chamber experiments at a stable temperature of 12°C, the seed treatments increased emergence by 8-16%.

To do this, α-amylases of the two insect species were extracted and their activities were determined using 1% soluble starch. Results showed that α-amylase, which hydrolyses starch, is present in both aphids. Also, it was shown that optimum pH and temperature for the α-amylases of both species is 7.0 and 40°C, respectively. Gel assays using zymogram analysis showed that in both aphid species more than one isoform (two isoforms) of α-amylases hydrolyszing carbohydrates are present.

Traps containing pheromone capsules could catch significantly more thrips than those without capsules, proving their efficiency in attracting and controlling this pest. In fact, greenhouses with traps with pheromone capsules caught 585.1, 526.7, and 668.8 adults/trap in a greenhouse with 10 traps with pheromone capsules on April 12, 19, and 26, 2012, respectively. The capture in a greenhouse with five traps with pheromone capsules was about 456.2, 412.8, and 431 adults/trap while in a greenhouse with five traps without pheromone capsules, the capture of F. occidentalis adults numbered 198, 257, and 302 adults/trap for the same three dates. Furthermore, traps with pheromone capsules captured males and females in equal numbers while traps without capsules caught much fewer males than females: 218.2 males/trap on April 26, 2012 in a greenhouse with five traps with pheromone capsules and 212.8 females/trap, 322.4 males/trap, and 342.3 females/trap in a greenhouse with 10 traps with pheromone capsules. In neither case were the differences significant. In contrast, in a greenhouse with five traps without pheromone capsules, the number of adults was about 88.6 males/trap, a significantly lower amount than the number of females/trap (213.4). This indicates that this pheromone plays a double role as a sex pheromone and as an aggregation pheromone by attracting both sexes. In fact, this double attraction approach improved the efficiency of these capsules by preventing the mating of untrapped females with males. This induced a high percentage of males and led to a decline in the thrips population on pepper flowers. Ten blue sticky traps with pheromone capsules reduced the thrips population more effectively in one week only than the use of five sticky traps, which took two weeks to achieve the control.

In the evolution of Integrated Pest Management (IPM), patterns and processes that influence spatio-temporal dynamics in insect populations tend to assume more importance compared to the classical theory. Geostatistics represent a valuable tool to investigate the spatial pattern of insect populations and to support pest control. After an explanation of the geostatistical analysis, in the present paper we provided an overview of practical applications in managing pests, focusing on fruit orchards and vineyards. The utility of geostatistical tools is illustrated with examples taken from field studies, with attention to the analysis of spatial patterns, monitoring schemes, use of traps, scale issues, precision targeting, and risk assessment maps. Potential approaches in the context of IPM are discussed in relation to future perspectives.
