톱다리개미허리노린재는 콩과작물과 과수에 경제적 피해를 주는 주요해충이다. 본 연구는 톱다리개미허리노린재의 온도에 따른 산란특성을 규명하고 수정란을 이용한 산란모형과 생명표 매개변수를 추정하기 위하여 15.8, 19.7, 24.0, 27.8, 32.6, 34.0, 35.5℃ 정온조건에서 실험을 실시하였다. 15.8℃를 제외하고 조사된 모든 항온온도조건에서 산란이 가능하였다. 암컷 성충 수명은 15.8℃ (110.5일)에서 가장 길었으며 온도 가 올라갈수록 짧아지는 경향을 보였다(19.7℃에서 76.6일, 35.5℃에서 20.6일). 전체 산란수와 수정란수는 24.0℃ (193.5와 151.2)에서 가장 많았으며 부화율은 27.8℃ (84.0%)에서 가장 높았다. 전체 산란수와 수정란수를 이용하여 산란모형과 생명표 매개변수를 비교하였다. 수정란수 를 이용시 온도별 총산란수 모형의 추정된 총산란수(159개)는 전체 산란수(190개)를 이용했을 때보다 적었다. 생명표분석에서 수정란을 이용하였을 때 개체군순증가율과 평균세대기간은 전체 산란수를 이용한 결과보다 작은 값을 나타내었다. 수정란을 이용한 산란모형 작성과 생명표분석은 실질적인 개체군변이를 이해하는데 도움이 될 것이다.

Riptortus pedestris is one of economically important insect pests in soybean fields. The study was conducted at seven constant temperatures of 15.8, 19.7, 24.0, 27.8, 32.6, 34.0 and 35.5℃. We compared the results from life table parameters and oviposition models of R. pedestris between two data sets. One included the total number of eggs and the other used only hatched eggs. When the total number of eggs were included to calculate the parameters the intrinsic rate of increase, net reproductive rate and mean generation time were 0.066, 58.13 and 61.45 at 24℃, respectively. These values were different only when hatched eggs were applied (0.064, 45.46 and 59.41, respectively). The parameters of temperature-dependent total fecundity and age-specific cumulative oviposition rate from each data set were different.

Riptortus pedestris is one of economically important insect pests in soybean fields. The study was conducted at six constant temperatures of 15.8, 19.7, 24.0, 27.8, 32.6 and 35.5℃. We investigated the biological traits of R. pedestris adults. R. pedestris adults survived at all temperatures tested but female did not oviposit under 15.8℃. The longevity of R. pedestris male was longer than that of female. Oviposition model was constructed using nonlinear functions and the number of eggs produced by a cohort of females was estimated in relation to constant temperature and adult age. The life table parameters in relation to temperature were analyzed.

The oriental fruit fly is a major polyphagous insect pest with a worldwide distribution. The effects of temperature on stage-specific development were investigated at eight constant temperatures (13.0, 14.4, 16.2, 19.5, 23.8, 27.7, 31.8 and 34.8℃). Stage-specific lower developmental thresholds and thermal constants were determined using linear regression. The lower and higher temperature threshold (TL and TH) were estimated using the Sharpe-Schoolfield-Ikemoto (SSI) model. The daily adult emergence frequency of B. dorsalis was estimated in relation to adult age and temperature. Thermal performance was compared among B. dorsalis populations from different locations in Taiwan.

과실파리류는 국내 60종의 검역 해충 가운데 42종을 차지하고 있다. 이들 대부분은 자연계 산물인 methyl eugenol (ME) 또는 raspberry ketone에 특이적으로 유인된다. 이들 유인물질을 파라핀 왁스를 이용하여 제형화하였고, 이를 대만에서 야외 유인 효과를 검증하였다. 이들 왁스 제형은 모두 델타트랩에 설치하고 8월 말경에 모니터링 한 결과 ME 왁스 제형은 오리엔탈과실파리(Bactrocera dorsalis)를 매일 60-80 마리 포획하 였다. 반면에 Cuelure 왁스제형은 오이과실파리(Bactrocera cucurbitae)와 B. tau를 유인하였다. 이러한 결과는 본 왁스제형이 이들 검역 해충에 대 한 국내 모니터링에 응용될 수 있다는 것을 제시하고 있다.

The soybean bug, Riptortus pedestris, is a polyphagous species and an important pest of soybean. We investigated the development periods and survivorship of R. pedestris egg and nymph stage. The study was conducted at eleven constant temperatures of 12, 14, 16, 18, 20, 24, 28, 32, 34, 35, and 36℃, respectively. Egg could not hatch under 14℃. Nymph could not develop to adult at 16℃.

Higher temperature threshold (TH) and lower temperature threshold (TL) were calculated by two nonlinear functions (Performance and SSI model). The adult emergence frequency of R. pedestris over full range of constant temperatures was simulated using developmental rate functions and Weibull function.
