“…For the MYD palm, stem and fruits was yellow in color, MRD was orange in color and Tagnanan was greenish in color. This color may attract the Oryctes rhinoceros which parallel with the study done by Mohammed and Hassan (2004) indicated that beetle highly preferred with the yellow color.…”

In the current study, population dynamics of males, females, and total males and females of Rhinoceros Beetle (Oryctes rhinoceros), namely, DXP PPNJ 1 and DXP PPNJ 2, was evaluated in different host varieties of oil palms and coconut palms of Ladang Penyelidikan Segamat in Johor State of Malaysia. Ethyl 4-methyloctanote had been used as a pheromone aggregation in this study. The results clearly indicated that population dynamics of Oryctes Rhinoceros (total male and female) in oil palms and coconut palms has significant difference within the whole sampling period. Based on cumulative Oryctes Rhinoceros caught, varieties of DXP PPNJ 1 and DXP PPNJ 2 had significant effects on its male and female population. MYD inclined more towards the population of Oryctes Rhinoceros male, female and total male and female, giving more impacts, when ccompared with MRD and Tagnanan. Both crops of same species/family were not recommended for planting in that area, because it facees similar problems of direct Oryctes Rhinoceros attacks, obviously affecting the yield. Therefore, MRD and Tagnanan, considered to be a cross-variety, had been recommended to farmers. Instead of having higher yields, farmers have lesser chances of severe attacks by Oryctes Rhinoceros, within the same time period. Contribution/ OriginalityThis study is important to study the abundance and the interaction of the rhinoceros beetle in oil palm and coconut palm. The abundance of male and female of rhinoceros beetle were observed and the interaction between the population dynamic, different types of crop and different plant variety in each crop also evaluated. Our findings are an attempt to provide adequate knowledge in recommending potential farmers to select the best variety, which is more resistant to Oryctes Rhinoceros attacks.

“…Oryctes rhinoceros more attracted to MYD which is yellow physical appearance compared to MRD and Tagnanan. Yellow sticky trap color attracted more insect pest compared to pink, green, and orange color (Mohammed and Hassan, 2004). Additionally, the composition of the chemical properties and nutrient elements probably differed among varieties.…”

“…Greenhouses provide better environmental conditions for plant growth and productivity. The important environmental factors affecting plant growth are temperature, relative humidity, light level, and carbon dioxide [3].Greenhouses are covered with transparent material that transmits visible light (400-700 nm), the main source of energy for photosynthesis and Lozano (1996) emphasized the importance of good light permeability in increasing greenhouse crop production [4]. Low density polyethylene (LDPE) has replaced the traditional glass cover due to its similarity in permeability of short wave transmission compared to glass but much higher permeability for long wave radiation.…”

Low-Density Polyethylene films of 100 μm thickness doped with Eu (TTA)3phen complex was hot-blown by a lab scale extrusion process. The ratio of the complex was varied from 0%, 0.025%, 0.5%, 0.1%, to 0.2% with respect to the total weight of LDPE. The mechanical properties of the films were measured according to ASTM D882, and ASTM D1938 standards. The optical and chemical properties were characterized by spectrofluorometer and FTIR respectively. FTIR characterization shows that Eu (TTA)3phen in LDPE films does not exhibit spectrum due to the dominant nature of amorphous LDPE. All emission transition lines of Eu3+ion for doped films were observed when excited at 394 nm, and the highest peak was detected at 608 nm. The peak intensity reached a saturation level at 0.1% doping ratio, while mechanical test showed that the tensile strength (TS) and elongation at break (EB) of machine direction (MD) oriented films decreased with increasing ratio of the complex, in which at doping ratio of 0.2%, both values dropped by 17.8% and 11.6% respectively.. These results indicate that different doped ratio of Eu (TTA)3phen affect significantly the film properties which offer possibility for an improved photoselective greenhouse plastic films. Keywords; LDPE, Eu (TTA)3phen, Photoluminescence.

This study deals with the effect of using two layers of polyethylene tightly fixed together along the frame elements of the walls and the roof, the space between the films was inflated at a pressure of 50 Pa, on, the effectiveness of evaporative cooling system during hot period, energy transport characteristics during cold period, and most relative vegetative growth parameters and production of egg-plant crop under eastern province climatic conditions of Saudi Arabia. These parameters were studied and compared with the commonly used double layers (without air gap) covering method. The results of this experimental work show that the greatest values of cooling effect (16.60°C) and effectiveness of evaporative cooling system (81.5%) were achieved inside the greenhouses covered with double layers of polyethylene with 9 cm air gap (G1), whereas, the effectiveness of cooling system (76.2%) occurred inside the greenhouse covered by double layers of polyethylene without air gap (G2). Consequently, Greenhouse 1 increased the effectiveness of cooling system by 5.3%. At nighttime the heat flux at the soil surface normally contributes heat energy to the greenhouse air, by releasing heat energy stored from the absorption of solar radiation at the floor surface on the previous daylight. Inside the greenhouse heat is transferred from the floor surface to the inside air by natural convection and thermal radiation emits from the floor or a uniform horizontal canopy surface of egg-plant. The hourly averages solar radiation recorded outside and inside the two greenhouses was 563. 8, 273.8, , consequently, the effective reflectance, absorption, and transmittance of the covering methods was on the average 48.56% and 53.34%, respectively. The air temperatures within the two greenhouses were at or around the desired level particularly in the greenhouse 1. Thus, the egg-plants were grown well during the experimental period. Moreover, the greenhouse 1, on the average, increased the rate of vegetative growth by 30.30% and fresh yield of egg-plant crop by 32.68%.
