EVALUATION OF SPECIFIC PHEROMONE TRAP DESIGNS AND COMPONENTS TO IMPROVE THEIR EFFECTIVENESS IN REDUCING THE RED PALM WEEVIL POPULATION IN EGYPTIAN PALM FARMS

Wael El Shafei, 2024

Due to the extreme danger of the red palm weevil (RPW), Rhynchophorus ferrugineus (Coleoptera: Curculionoidea: Dryophthoridae) on date palms and its rapid spread in many countries in the world. This work was carried out to evaluate the effect of using different pheromones, baits and trap shapes on the attraction of the RPW adults by pheromone traps in date palm plantations. Results revealed that the traps contained Rhyncho gel pheromone recorded the highest average of captured RPW 20.17 adults/ trap compared to the three other tested pheromones, Rhyno cap, English and Costa Rican which recorded, 17.44, 12.94 and 7.44 adults/ trap respectively.

Influence of Nano-Chitosan Loaded with Potassium on Potassium Fractionation in Sandy Soil and Strawberry Productivity

Fadl Hashem, 2023

Under sandy soil conditions, increasing the efficiency of potassium (K) fertilizers is considered to be a major limiting factor for improving the productivity and quality of fruit crops. In this context, utilizing nanotechnology has emerged as a novel technique to increase the efficiency of K applications. In our study, two field trials were conducted, in two consecutive seasons (2019/2020 and 2020/2021), to compare the effects of nano-chitosan loaded with K as a foliar treatment with those of conventional soil applications of K on plant growth, yield, and quality of strawberry plants grown in sandy soil. Strawberry plants were treated with 12 different treatments, which were replicated three times in a randomized complete block design in each growing season. Potassium sulfate (K2SO4, 48% K2O) was applied to the soil at a rate of 150.0 kg acre?1 (recommended rate, 100%). Meanwhile, the spraying of nano-chitosan loaded with K was applied at 1000 mg L?1 as a control. In addition, K2SO4 was applied either individually or in combination at the rate of 112.5 or 75.0 kg acre?1 with four nano-chitosan-K dosages (250, 500, 750, and 1000 mg L?1). After harvesting, soil samples were collected and prepared to determine K fractions. As well, plant samples were collected to determine the vegetative growth parameters and the foliage content of NPK and chlorophyll. Eventually, the yield traits and quality parameters were evaluated. A principal component analysis was conducted to determine the interrelationships of the treatments’ averages and their effects on yield components and quality traits. A combined analysis was performed for the two studied seasons and the values were the mean of six replications. The results indicated that the application of common K fertilizer (150.0 kg K2SO4 acre?1) resulted in the maximum increase in soluble and exchangeable K in the soil, which was comparable to those observed with 112.5 kg K2SO4 acre?1 + 1000 mg L?1 nano-chitosan-K and 112.5 K2SO4 acre?1 + 750 mg L?1 nano-chitosan-K. The total yield, marketable yield, and fruit firmness were all significantly increased by the latter two treatments compared to the control group. Furthermore, plots treated with 112.5 kg K2SO4 acre?1 + 1000 mg L?1 nano-chitosan-K significantly increased the total soluble solids, vitamin C levels, acidity, total sugar, and anthocyanin levels in strawberry fruits. In conclusion, under sandy soil conditions, the utilization of nanoparticles could be an indispensable tool for manipulating fertilization management when cultivating strawberries. The K status of the soil was improved by applying 75% of the recommended dose of mineral K in combination with 1000 or 750 mg L?1 of nano-chitosan-K, without compromising strawberry yield or quality.


AN ECONOMETRIC ANALYSIS FORTHE IMPACT OF CLIMATIC CONDITIONS ON THE PRODUCTIVITY OF MANGO CROPS IN EGYPT BY USING PANEL DATA MODELS

Horizontal agricultural expansion is one of the most important pillars of
the national economy in Egypt, so the country makes strenuous efforts
to make optimal use of agricultural resources, and despite these efforts,
the climate prevents it
.Recently, global warming has increased and
climate change is expected to worsen the frequency, intensity, and
impacts of some types of extreme weather events that affected mango
productivity during the last years, which led to a decrease in
productivity by about 37%, with a value of financial losses amounting
to 4.8 billion pounds in 2021.Therefore, the research aims to estimate
the impact of extreme weather on mango productivity during the last
three years (2021-2019) at four studied governorates representing 75%
of the total area of mango in Egypt. The Fixed Effect Cross of Panel
Data Model was adopted as the appropriate model, to illustrate the
impact of the phenomena on the productivity of mangoes. The results
show that there is a statistical significance and a negative effect for both
the minimum and maximum temperatures, as productivity decreases by
about 1.05%, and 1.79% with an increase in each of the minimum and
maximum temperatures by 1%, respectively. The negative impact has
been shown on the governorates of Buhaira and Ismailia. Also, the
individual effect was studied for each month,it was found that there was
a statistically significant negative effect of the minimum and maximum
temperatures for the months of flowering and fruiting.


Effectiveness of Pitfall Trap Colors in Monitoring Adults of Blister Beetle Meloe proscarabaeus Linnaeus, 1758 (Coleoptera: Meloidae) in Faba Bean Fields at El-Farafra Oasis Egypt

The blister beetles Meloe proscarabaeus Linnaeus, 1758 (Coleoptera: Meloidae), is a
dangerous pest that threatens the agriculture of faba bean fields in El-Farafra Oasis,
New Valley Governorate. In this study, an evaluation of the efficiency of different
pit-fall trap colors for capturing adults of the blister beetles has been performed in
faba bean (Vicia faba L.) fields. The experiment revealed that the green and red
traps showed the highest number of captured beetles during the 2020 and 2021
seasons, which was highly significant to other traps’ colors. On the other hand,
black, blue, gray, white, and yellow traps showed insignificant differences in the
number of captured beetles. Concerning the sex of trapped beetles; it could be
highlighted that the green trap attracted more female beetles than males with
significant differences. Inversely, the red color trap attracted more males than
females with significant differences. Approximately 40% of the captured beetle
population was recorded in March, while only 11% were trapped in April. A Green
pit-fall trap could be deemed a new estimating assay to suppress M. proscarabaeus
adults in faba bean fields since the color trap variation affected the number of
captured beetles. Therefore, color traps can be relied upon as an effective method
in controlling beetles without the number of beetles reaching the limit of economic
damage and in a manner that is safe for the environment.
