The incidence of dengue hemorrhagic fever (DHF) is still a public health problem in Indonesia. Observations over a period of 20 to 25 years since the beginning of the discovering of the disease, has show the increase of the diseases incidence every five years. The purpose of this study are 1) study the diversity of Aedes’s mosquitoes in Sukabumi City, 2) measure the Aedes population based on the number of eggs and ovitrap index, and 3) to know the correlation between ovitrap index and house condition. Aedes eggs were collected from 14 villages in Sukabumi City that has the highest incidence rate, started from May 2015 until August 2015. Collecting eggs is done by setting a trap eggs (ovitrap) as many as 230 pieces in 115 homes (indoor and outdoor). The results showed that Ae. aegypti were found inside houses and Ae. albopictus were outside houses. The number of eggs collected from ovitrap inside the houses were three times more than those collected from outside. Ovitrap index inside houses was 60%, or 1.6 times more than the ovitrap index outside the houses (37%) in 14 villages in Sukabumi. Houses with poor ventilation and sanitation increased the risk 3.09 times of number of ovitrap index. The results of this study could be use as basic information for the communities to improved environment hygiene through reduced mosquito breeding sites, thus degraded the incidence of dengue

The existence of Ephemeroptera, Plecoptera, and Trichoptera (EPT) in a body of water can be used as indicators of the quality of the waters. The aim of this study were 1) to know the diversity of EPT insects in Jangkok River, Lombok, West Nusa Tenggara, 2) determine the water quality of Jangkok River based on family biotic index (FBI), and 3) to know the effect of physical, chemical, and biological of environment parameters on the presence of EPT insects. Sampling was conducted in Jangkok River, Lombok, West Nusa Tenggara, in the dry season of July 2016. EPT groups insects were taken using water nets and eckman grab in 22 sampling points that was randomly determined in systematic random sampling. Data of physical, chemical, and biology of waters were also taken in these sampling points. Water quality is determined by the score of FBI, and the multiple correlation analysis to determine the relationship between physical and chemical parameters with the presence of EPT. Biological parameter was analyzed descriptively. The influence of biological parameter was determined by descriptive analysis. The study found 902 individuals of EPT belonging to 12 family and 12 genera. In the upstream we found 788 individuals (12 family and 12 genus), in the middlestream found 114 individuals (10 family and 10 genus), while in the downstream the EPT was absent. From the seven physical and chemical parameters of waters tested, only water temperature has significant correlation with the presence of EPT. The differences of water temperature in these area were caused by the covering and heterogeneity of the vegetation in the river side in each area. FBI score for upstream was 3.6 which indicates that the quality of the waters are very good. In the middlestream, the FBI score was 4.6, and it was categorized as good. In the downstream, results of the FBI get infinite value that entered the category as very bad.

Siklus hidup dan statistik demografi kutukebul Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) biotipe B dan non-B pada tanaman cabai (Capsicum annuum L.) Purnama Hidayat; Hazen Arrazie Kurniawan; Lutfi Afifah; Hermanu Triwidodo

The whitefly Bemisia tabaci (Gennadius) biotype B also known as Bemisia argentifolii (Gennadius) is a more malignant whitefly biotype in damaging plants compared to non-B biotype. Currently the whitefly B. tabaci biotype B has been reported to exist in Indonesia. Basic information such as life cycle, length of life, fecundity, and breeding ability of a whitefly is important information as a basis in preparing the whitefly control strategy. The aim of this research was to study the life cycle and demographic statistic of the B. tabaci biotype B and the non-B biotype on chili pepper. The study was conducted by observing the development of the whiteflies from eggs to adult in a growth chamber that the temperature and lighting were controlled. Observations were made on several aspects of biology and some parameters of demographic statistics. The results showed that the biotype B of B. tabaci has several different biological aspects with the non-B whitefly in chili pepper. The life cycle of the biotype B of B. tabaci and the non-B were different, 33.27 and 30.86 days respectively. The biotype B of B. tabaci had a net reproduction rate (R0) which was similar to that of the non-B biotype as well as the average of its generation. However, the intrinsic increase rate (r) of the biotype B B. tabaci was 2.5 times shorter than the non-B biotype. The biotype B of B. tabaci doubled its population (DT) 2 times faster than the non-B biotype. It is clear that the biotype B of B. tabaci potentially more dangerous than the non-B.

Thrips parvispinus Karny (Thysanoptera: Thripidae) is one of the major pests of chili pepper in Indonesia. The pest can be found on all parts of the plants, especially flowers and leaves. Information of the biology and demographic statistic of T. parvispinus are still limited. The objective of this research was to study the biology and demographic statistic of T. parvispinus in Bogor. Fifty individual of 1st instar nymphs were reared on caged chili pepper leaves (d = 4 cm and h = 8 cm). Chilli pepper leaves were replaced everyday and observed daily to determine the development and number of offspring eggs. The collected data were used to obtain information about the biology of the pest such as the stadia of each instar, preoviposition period, life cycle, adult longevity, and fecundity. The data were also used to construct life tables for demographic statistic analysis using of the Jackknife method. There were 5 phases of immature stages of T. parvispinus: eggs, two instars nymph, prepupa, and pupa with their stadia were 4,79, 1,36, 3,54, 1,08, and 1,96 days respectively. The preoviposition period of the insect was 1,11 days, life cycle was 13,68 days, female longevity was 8,55 days, male longevity was 6,00 days, and fecundity was 15,33 eggs per female. The population development of T. parvispinus followed type III of survivorship curve with intrinsic rate of increase was 0,15 individual per days female per days, net reproductive rate was 5,71 individual per female per generation, generation time was 11,49 days and doubling time was 4,57 days.

Presence of insects in agricultural habitat is affected by several factors such as natural habitat. The objective of this research was to study the effect of natural habitat on diversity and abundance of flower-visiting insects in cucumber fields. Ecological observation was conducted in 12 cucumbers fields located in regencies of Bogor, Cianjur, and Sukabumi, West Java. Cucumber fields were categorized in two different distant form natural habitat i.e. near natural habitat (less than 200 m) and far from natural habitats (more than 1000 m). The observations of flower-visiting insects in cucumber fields were conducted by counting the number of flower-visiting insects that perched within 100 flowers in four different transects. The result showed that the presence of natural habitat affected species richness but not the abundance of flower-visiting insects in cucumber field. The dominant species of flower-visiting insects in cucumber fields were Aphis sp., Tapinoma sp. and Thrips parvispinus Karny, while the most dominant pollinator was Apis cerana Fabricius. The distance of natural habitat from farmland affected the presence of flower-visiting insects especially pollinator insects that provide important services on enhancing crop yield.

Tetragonula laeviceps (Smith) is one of the most common species of stingless bees in Indonesia. However, only few publications available on the flight activity rhythms of the species. Research was conducted with the objectives to determine flight activity of T. laeviceps in relation to daily times and various weather elements. Three colonies of T. laeviceps were observed hourly for 5 minutes beginning at 06.00 a.m. until 06.00 p.m. Number of bees entering with pollen or resin, as well as exiting with waste were counted. Flight activity was significantly different (P < 0.001) among times of day. The preferential times (acrophases) of flight activities occurred at afternoon (11 a.m. to 12 a.m.). Number of entrance and exit flights positively correlated (moderate) with temperature and light intensity, while negatively correlated (moderate) with relative humidity.
