Objective: To determine abundance, distribution and diversity of potential breeding container habitats of the dengue vectors in public places including schools, restaurants,mosques and parks in southwest areas of Penang Island, ***: Premises at restaurants, schools, parks and mosques were surveyed simultaneously and inspected visually for container habitats and production of immature mosquitoes from March 2015 to March 2016. abundance(mean ± SE) of breeding containers between sites was compared using One-way ANOVA. Independent sample ttest was used to compare total number of Aedes albopictus(Ae. albopictus) and Aedes aegypti(Ae. aegypti) ***: The surveyed locations yielded a total of 3 741 breeding containers and 19 537 immature mosquitoes from four areas. Concurrent artificial and natural containers produced 78.4% immature Ae. albopictus and 6.3% Ae. aegypti mosquitoes in wet season,with 14.2% Ae. albopictus and 1.1% Ae. aegypti mosquitoes in dry season. Artificial containers accounted for 98.1% of the total containers recorded, with restaurants being the most productive locations(8 012) and schools being the least productive(2 234).Conclusions: It was concluded that public places are good sources of potential container habitats of Aedes mosquitoes in Penang Island, Malaysia and Ae. albopictus has exclusively replaced the home-grown Ae. aegypti even in urban areas. Therefore, treatment of artificial containers in such locations is critical in Aedes mosquito control campaigns during dengue outbreaks.

Spatial distribution of banana skipper （Erionota thrax L.）（Lepidoptera： Hesperiidae） and its parasitoids in a Cavendish banana plantation, Penang, Malaysia

引用

Insect Science 2006年第5期13卷 381-389页

作者： JUSTIN N. OKOLLE MASHHOR MANSOR abu hassan ahmad School of Biological Sciences Universiti Sains Malaysia Minden Penang Malaysia

Spatial distribution of immatures of the banana skipper （Erionota thrax L.） and their parasitisms from three major parasitoids were studied in a Cavendish banana plantation from April 2004 to December 2004. Infestation levels and parasitism of E. thrax life stages were recorded from bunched plants （BP）, flowering plants （FP）, preflowered plants （PF）, broad leaf followers （BLF） and narrow leaf followers （NLF）, as well as on well managed and poorly managed plants. Mean numbers of the immatures and numbers parasitized from the nine blocks in the plantation were fitted to four dispersion indices. Significant numbers of E. thrax immatures and those parasitized by Ooencyrtus erionotae, Cotesia erionotae and Brachymeria albotibialis were recorded from BLF and PF; no eggs were found on BP and FP. Although infestation was higher on well managed plants, only larval parasitism was significantly different. Three of the four indices indicated that eggs and larvae were random while all the indices showed pupae to be clumped. Parasitized eggs and pupae were clumped （4/4 indices） while 3/4 indices revealed a random pattern for parasitized larvae.

作者： Amir Shah Ruddin Md Shah Mashhor Mansor Shahrul Anuar Mohd Shah Che Salmah Mohd Rawi abu hassan ahmad Ibrahim Jaafar School of Biological Sciences University Sains Malaysia 11800 Penang Malaysia

A survey was carried out at the largest rice cultivation area in Peninsular Malaysia,the Muda rice *** main objective of this study was to document the overall biodiversity associated with this unique agroecosystem by using a combination of sampling techniques in order to record different groups of fauna and *** total number of biota recorded and identified from the rice field ecosystem during the study period consisted of 46 species of zooplankton,81 species of aquatic insects,5 species of rodents,7 species of bats,87 species of birds,11 species of fishes and 58 species of weeds.A long-term study should be carried out as more species are expected to be recorded when more of the Muda rice agroecosystem area has been sampled to obtain sufficient information on the Muda rice agrobiodiversity.

Objective:To generate life table characteristics for the dengue vector Aedes albopictus(A. albopictus) under uncontrolled conditions,incorporating both the aquatic and the adult stages. Methods:Ten females derived from wild pupae were allowed to fully blood-feed on restrained mice.774 eggs were hatched in seasoned water.F1 larvae were followed for development until their F2 counterparts emerged as *** population parameters were monitored(Fl) or estimated(F2).Results:*** exhibited increased fecundity and egg hatch success. Immature development was *** survival was high,with lowest rate in the pupal *** emergence was about 81%and sex ratio was close to 1:*** mortality(K) was about 28%.A high proportion of females completed a reproductive cycle and the obtained parity rate was predicted to lead to higher fecundity in the next ***:It can be concluded that natural *** populations in Penang seem largely determined by quick development in combination with low immature loss and increased oviposition.
