AbstractAdult Calosoma sycophanta L. (Carabidae: Coleoptera) male and female pairs in a laboratory arena were observed for up to 30 days with a video recorder. Beetles were visible (i.e. not hiding) or in soil (i.e. female ovipositing) especially during night hours. Feeding on gypsy moth larvae occurred any time of the day or night. Male and female beetles were most active during the time when female beetles were ovipositing. Females spent more time eating and staying in soil than did males, but males tended to move around the arena more than did females. Based on results from this study, it is expected that, in the forest, C. sycophanta females will spend most of their time hidden in leaf litter or ovipositing. Males are more likely to be seen because they spend more time moving about, probably seeking mates.

This study aimed to explore the source of IL errors on male and female students’ pronunciation. The participants in this research were ten college students who were participated in an English speech contest organised by English Student Association of UNNES 2019. The ten participants consist of five male and five female students who came from different kinds of University in Indonesia. In this study, the researcher used a descriptive qualitative method to analyze the data by using a video recorder as an instrument to collect the data. The result of this research showed that there were four sources of errors which influenced male and female students in producing IL errors on pronunciation. Those were L1 transfer, different form of plural between L1 and L2, the existence of sounds with the same phonetic features but different in distribution, and English foreign sounds. The second result described that the source of errors on male and female college students was mostly similar, and they had no significant differences. Last result showed that male students made more variation of IL errors on their pronunciation than female students.

Nesting Activity

Osmia cornifronsRadoszkowski (Hymenoptera: Megachilidae) is utilized as an alternate pollinator toApis melliferaL. (Hymenoptera: Apidae) in early-season fruit crops. This study was conducted to investigate nesting activities and associated behaviors ofO. cornifrons.Osmia cornifronsnesting activity was recorded by using a digital video recorder with infrared cameras. Nesting behavior of ten femaleO. cornifronswas observed, and the number of nesting trips per hour was recorded. Trends in daily activity were determined with regression analysis, and chi square analysis was used to determine ifO. cornifronsspent a greater amount of time performing certain activities. The percentage of time required to gather nesting resources and complete nest construction activities was recorded from the video footage. Results of this study showed that pollen gathering was the most time-consuming gathering activity, requiring221.6±28.69 min per cell and cell provisioning was the most time-consuming intranest activity, requiring 28.9 min ± 3.97 min. We also found thatO. cornifronsactivity was correlated with time of day, temperature, and precipitation. Various nesting behaviors, including cell provisioning and partitioning, oviposition, grooming, resting and sleeping, nest-searching, and repairing behaviors, are described in this paper.

Holorusia Loew, 1863 (Diptera: Tipulidae) is a relatively large crane fly genus with a wide distribution in the Afrotropic, Australasian–Oceanian, Eastern Palearctic, Oriental and Nearctic Regions. Although the genus is well known to include the largest crane fly species, the immature stages are, thus far, only described for the larva and pupa of the North American Holorusia hesperea Arnaud & Byers, 1990. In this study, we describe for the first time the egg, larva and pupae of the Japanese Holorusia mikado (Westwood, 1876). Larvae were collected from semi-aquatic habitats, from slow flowing areas of streams and small waterfalls where leaf litter accumulates; the larvae are detritivores and feed on wet, decomposing leaves. The larvae were reared to adults in the laboratory. Morphological characters of immature stages discussed with comparison with the North American H. hespera. Male and female genitalia are illustrated and described in detail for the first time.

AbstractDifferences in responses of males and females of Lucilia cuprina (Wiedemann) to carrion-baited traps were examined in Australia in relation to time of day, temperature, wind speed, relative humidity and solar radiation. The differences were small compared with responses obtained for the combined sexes (total catch), but the results were inconsistent over the four seasons of trapping. The seasons with most data (1975–1976 and 1981–1982) gave reasonably consistent results. Seasonal differences, although significant, were small enough to neglect for the purpose of standardizing trap catches. Time-of-day effects were also unimportant, except that males tended to be less active than females during the early morning (dawn-0900 h) and more active than females during the late afternoon (1500 h-dusk). Separate models are presented for standardization of male and female catch rates; the estimates differ from those obtained from total catches, but the differences are small compared to the observed day-to-day variation in catch rates.
