Laboratory and field studies were conducted on some aspects of biology and control methods of fruit stalk borer Oryctes elegans Prell., the study was conducted in date palm orchards in south Baghdad during the years 2009 and 2010. The laboratory rearing result ofO. elegans indicated that the larval stage period was very long reached 6 months, the body weight of the mature larva was 7.61 gm, the length and body circumference were 7.58 and 5.23 cm respectively. The period of pupa stage was 19 day and 2.97 gm body weight, while the length and body circumference were 3.74 and 3.21 cm respectively .While the weight of adult stage was 1.67 gm and 3.14 cm, 2.71 cm for the length and circumference body respectively. Results of hand collection larvae in palm trees during the regular annual service, showed reduction in population density of adults to 1.4 adult/trap per week compared with 3.3 and 14.0 adult/trap per week in the orchards were larvae collected partially and without hand collection by using the light traps with solar energy (Magna Traps, Russell IPM) respectively. Also, the study proved the existence of an inverse relation between the moon light and adult activity, which affected on the adult number cough in light traps. These results indicated that the hand collection of larvae works during months January, February, March and April at synchronized with the larval stage on palm trees, and use Magna Traps as an effective method to control O. elegans through IPM programs in palm orchards. 展开更多

(1824) is one of the most important pest that can infest orchards if its spread is not controlled. Among the preventive measures recommended in the fight against this pest, we are interested in looking for varieties that are less favorable to the development of this pest among different varieties of fig trees in our region. The biological parameters of the fruit fly which were followed in this study are duration of pupation, rate of emergence, sex ratio and longevity of males and females. The results show that these parameters vary depending on the variety of fruit. 展开更多

Fruit flies are causing extensive socio-economic losses in citrus orchards in Ghana. The flies as quarantine pests have detrimental effects on the export market due to international trade regulations. Oecophylla species have been tested as biological control agents on other crops, and have shown great potential in reducing the effects of pests. The effectiveness of Oecophylla as a biocontrol agent of fruit flies was compared with insecticide, Cypermethrin + Dimethoate (Cydim super~) at Forest and Horticultural Crops Research Centre, Kade, in the Eastern Region of Ghana. The results have shown that trees colonized by Oecophylla had between 6%-10% fly infestation and Cypermethrin + Dimethoate (1614 mg a.i. mL~ tree"1) recorded 3.0% infestation. Cypermethrin + Dimethoate treatment recorded 3.50 ~ 0.87 dropped fruits, and Oecophylla colonized-trees recorded 15 to 19.20 -4- 3.61. Oecophylla colonized-trees recorded yield values from 12.90 to 15.20 tons ha-~ whilst Cypermethrin + Dimethoate treatment recorded 27.90 tons hat fruit yield. Total number of fly landings in the presence of Oecophylla (72.00) was significantly lower than the absence of Oecophylla (114.20). Set-up with no Oecophylla recorded the highest infestation index (71.17) while the presence recorded 45.83. These results suggest that Oecophylla longinoda can be used as a biocontrol agent for IPM programs in citrus orchards. 展开更多

Spatio-temporal relationship of the phytophagons Clania miniscula (Butler) and garden spiders was examined through analysis of their niche and distribution as they occur in sasanqua orchard in Southern Anhui, China from June 2003 to May 2004. The dynamic relationships between Clania minuscula and garden spiders were seasonal in time and space. Spatio-temporal niche breadth was high for the two groups, ranging from 0.57 to 0.98; niche overlap was also high between the two groups from 0.76 to 0.96 during the seasons of June 2003 to May 2004. Geostatistical results indicated that Clania minuscula and garden spiders were aggregated during the emergence periods. The pest Clania minuscula was spatially dependent to a range from 33.48 to 46.84 m while spatial dependence from 30.93 to 51.11 m for garden spiders. The correlation analysis of distribution maps further illustrate the distribution of garden spiders always coincided with that of Clania minuscula. These results showed spatio-temporal synchrony of Clania minuscula and garden spiders at different periods. Adequate knowledge of spatio-temporal correlation between Clania minuscula and garden spiders contributed to provide information for biocontrol at different periods in sasanqua orchard. 展开更多

Ethanolic extracts of five plant material from Eucalyptus gluaca, Melia azadrach, Mentha arvensis, Olea europaea leaves and periearp of Punica granatum were investigated for insecticidal activity against the confused flour beetle Tribolium confusum DuVal in the laboratory. Different concentrations 2.5%, 5%, 7.5%, 10% using filter paper test were implemented in the experiment. Mortality was assessed after 24, 48, 72 hrs of treatment and LDs0 were calculated at respective time intervals. Data analysis was made by using factorial Complete Randomized Design (CRD). The results revealed that all of the tested materials with some variations had lethal effects against the pest as compared with the untreated check. The time 24 h showed higher insecticidal effect with the tested concentrations for the larvae and adult of Tribolium confusum. Strong toxicity effect was observed at concentration 5% of M.. arvensis for adult followed by E. gluaca, O. europaea, M.. azedrach and P. granatum. For larval stage the extract of O. europaea and E. gluaca with concentration 7.5%, 1%, respectively caused high mortality followed by M. arvensis, M. azedrach and P. granatum. The LDs0 values for adults and larvae were calculated to be 1.33 and 1.42 with M.. arvensis and O. europaea, respectively. 展开更多

Population dynamics of Bactrocera dorsalis Hendel (Diptera: Tephritidae) were studied through pheromone trapping over 4 years (1997, 1999, 2000, 2003) in the Kunming region, a high plateau area in southwestern China. B. dorsalis immigrates from southern Yunnan to Kunming each year, and occurs during early May through November. Annual trap captures recorded an increase in the B. dorsalis populations from May to July, when they peaked in abundance, and a decline until November. No flies were detected from November to April. The fruit flies had two generations. There was considerable overlapping due to the continuous arrival of immigrating flies during the summer months. Annual capture rates were significantly related to numbers of flies caught in July when peak captures were recorded; whereas the peak captures, in turn, positively depended on numbers of flies recorded in May, the first month of fly appearance in the current year. It suggested that the annual population abundance was mainly dependent on the size of the initial emigrating population. A daily average temperature of 18℃ was probably the threshold temperature required for the flies to undertake long-range dispersal, which partially explained the start of the fly in May each year on this high plateau. Under field conditions, the fruit flies can withstand 13℃ as a daily average temperature. No flies were recorded in any of the study years at a daily temperature colder than 10 ℃. 展开更多

The Morpho butterfly is famous for its typical structural color and has increasingly attracted the interest of scholars in a wide variety of research fields. Herein, it was found that the color of Morpho menelaus butterfly wings is not only structure-based but also viewing-angle-dependent. Firstly, the discoloration effect of this typical butterfly was confirmed by a series of experiments. Then, the general form, arrangements, and geometrical dimensions of the scales were observed using a stereomicroscope. Scanning electron microscopy was also used to examine the two-dimensional morphologies and structures of a single scale. Afterwards, one model with the optimized three-dimensional profile of the structure was described using Pro-engineer software. The associate model was then analyzed to reconstruct the process between the incident light and the model surface. Finally, the mechanism of the angle-dependent discoloration effect was analyzed by theoretical calculation and optical simulation. Different light propagation paths and the length of the incident light at different angles caused destructive or constructive interference between the light reflected from the different layers. The different spectra of the reflected light make the wings appear with different structural colors, thereby endowing the angle-dependent discoloration effect. The consistency of the calculation and simulation results confirms that these structures possess an excellent angle-dependent discoloration effect. This functional "biomimetic structure" would not only be of great scientific interest but could also have a great impact in a wide range of applications such as reflective displays, credit card security, and military stealth technology. 展开更多
