The subgenus Anastega is fused with the subgenus Orthostegana as syn. nov.. Four new species are described from Yunnan, China： Stegana （Orthostegana） flavicauda Zhang ＆ Chen sp. nov., S. （O.） hirsutinna Zhang ＆ Chen sp. nov., S. （O.） hylecoeta Zhang ＆ Chen, sp. nov. and S. （O.） multicardua Zhang ＆ Chen sp. nov.. Two known species： S. （O.） curvinervis （Hendel, 1914） and S. （O.） singularis Sidorenko, 1990, comb. nov. are described complementally. A table showing uncorrected pairwise p-distance among the DNA sequences of the mitochondrial COl and ND2 genes of six Orthostegana species is provided.展开更多

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

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
