In natural conditions, the black soldier fly, Hermetia illucens (L.) (Diptera: Stratiomyidae), colonizes in warm temperate regions, and is active in Korea from May through October. Information on black soldier fly rearing, which is affected by seasonal factors in Korea, is limited. This species colonizes and oviposits in a wide variety of decomposing vegetable and animal matter. For mass rearing of black soldier flies, the egg deposition methods are dependent on sunlight and oviposition sites. In this study, we investigated the substrates and oviposition sites preferred by black soldier fly in artificial rearing system. Our results showed that as black soldier flies prefer mating under sunlight, they prefer ovipositing at sites where adequate sunlight and food substrate are available. Further detailed research is required to develop methods for artificially rearing black soldier fly throughout the year in Korea.

Timing of oviposition, nuclear maturation of oocytes, egg-sperm contact and brooding were observed in the giant fresh-water prawn Macrobrachium rosenbergii reared in the laboratory. When a pre-spawning molted female was transferred to the male, the female oviposited commonly at 5 to 10 hr after mating. The first polar body were extruded within 2-3 min after spawning. The egg chromosome progressed to release second polar body by 30 min and mitotic nuclear division occurred in 8 hr after spawning. Thumbtack-shaped spermatozoa were seen peneterating egg membrane with their spike directed forward. Transformation of spermatozoa and fertilization membrane could not be observed by light microscopy. The elapsed hours from oviposition to the end of brooding wee taken in 5-7 hr. Brood size for female 9 cm and 18 cm in body length was estimated to be 10,000~15,000 and 100,000 eggs, respectively and is proportional to the total length of the berried females. The ovigerous females reared at chlorinity of 2.21~4.25$\textperthousand$Cl. showed a normal egg development up to hatching.

금잔화, 들깨풀, 수국등 10종의 야생식물잎의 추출물이 담배나방(Heliothis assulta) 유충의 발육과 성충의 산란에 미치는 영향을 조사하였다. 그 결과 유충이 높았으며 대부분 1영과 2영 기간중 먹지않기 때문이다. 여기서 살아남은 유충들도 발육기간 및 탈피횟수는 증가하는 경향을 보였다. 이중 갈매나무와 때죽나무의 추출물은 성충의 산란도 상당히 억제하였다.

온도가 벼잎벌레의 산란 및 발육에 미치는 영향을 조사하였다. 조사온도는 15, 20, 23, 25, $28^{\circ}C$로 하여 수행한 결과 발육기간은 $15^{\circ}C$에서 $28^{\circ}C$에서 최고를 이루고 다시 낮아지는 경향을 보였다. 발육기간은 저온보다 고온($28^{\circ}C$)에서 짧은 경향을 보였다. 알발육영점도는 $6.4^{\circ}C$, 총유효적산온도는 75.8일도였다. 이 결과는 $23^{\circ}C$가 벼잎벌레의 산락적온으로 추정되었다.

The diapause of $Telegryllus$ $emma$, the Emma field cricket, was investigated to study the ecological characteristics of the species. Changes in the volume, oxygen consumption, and water content of T. emma eggs were followed from oviposition. An increase in volume, oxygen consumption and water uptake occurred from 7 to 8 days following oviposition. The oxygen consumption of the eggs increased slowly for 7 days following oviposition, but then decreased until 15 days following oviposition. These results showed that a physiological change at diapause initiation affected the volume, water content, and oxygen consumption of the $T.$ $emma$ eggs. An experimental investigation of egg hatching showed that the eggs could be stocked at $10^{\circ}C$ for 40 days with a 14 day pre-period after laying and yield, 62.1% hatchability under these conditions. Maintaining the temperature at approximately $10^{\circ}C$ was favorable for hatching. Another experiment on egg hatching showed that the storage of eggs at $10^{\circ}C$ from 40 to 180 days would ensure satisfactory, hatching capacity.

작물의 화분매개를 위해 사용되고 있는 뒤영벌 종 토종 호박벌에 적합한 전기를 이용한 산란유도장치를 본 연구에서 처음으로 개발하였다. 개발된 산란유도장치는 여왕벌의 산란이 이루어지는 산란상자, 산란상자의 온도 유지를 위한 온도제어장치, 열전도부 및 이를 지탱할 수 있는 이동형 선반 등으로 구성되어 있다. 개발된 산란유도장치와 기존의 온수 보일러 장치를 이용하여 토종 호박벌의 산란성과 봉세발달을 조사한 결과, 개발된 산란유도장치에서 산란율이 3.9% 높고, 봉군형성율도 5.2% 높은 것으로 확인되었다. 특히 개발된 산란유도장치는 기존의 장치보다 설치비용을 75% 줄일 수 있었고, 에너지 절감이 가능하여 유지비용에 있어서도 효과적이었다. 이러한 결과들로 볼 때, 본 연구에서 새롭게 개발된 전기 산란유도장치는 비용절감과 함께 효과적인 산란유도에 따른 호박벌의 대량생산에 기여할 수 있을 것으로 판단된다.

Bumblebees are widely used to pollinate crops in greenhouses and fields. Here, we investigated whether different wake-up treatments during a short period of 1~3 days just before indoor rearing has any effects on oviposition and colony development of $CO_2$-treated Bombus ignitus queens and artificially hibernated B. terrestris queens The wake-up regimes were defined as 16L for 1 day (16L-1), 16 L per day for 3 days (16L-3), 24L for 1 day (24L-1), or 24D for 1 day (24D-1). Among these wake-up treatments, the oviposition rate and preoviposition period of B. ignitus queens reared at 24L-1 were 16.7~25.1% higher and 1.0~3.5 days shorter than other wake-up treatments. B. terrestris queens reared at 24L-1 also showed the best results for egg-laying characteristics, which were 8.9~18.8% higher for oviposition and 0.6~3.5 days shorter for preovipostion period than other wake-up treatments. Furthermore, B. terrestris queens reared at 24L-1 were 17.5% and 13.8% higher in rate of colony foundation and queen production, respectively, than other wake-up treatments. These results show that the most favorable wake-up treatment just before rearing for egg-laying and colony developmental characteristics of B. ignitus and B. terrestris queens was 24L-1. Overall, our findings indicate that a wake-up treatment just before rearing was effective for colony initiation and colony development of bumblebee queens.

아메리카잎굴파리의 내부기생봉인 Neochrysocharis formosa의 산란과 기주체액섭취 선호성을 조사하였다. N. formosa는 기주유충의 몸 뒤쪽에 대부분 산란하였다. 온도 조건에 따른 일산란수와 일기주체액섭취수를 조사한 결과 온도가 높을수록 증가하는 경향이었으며 15, 20, 25, 3$0^{\circ}C$에서의 산란수와 체액섭취수의 비율은 각각 0.5, 0.9, 1.0, 1.0이었다. $25^{\circ}C$ 항온조건하에서 N. formosa의 총산란수와 기주체액섭취수는 각각 176개 188.7개이었으며 산란수와 기주체액섭취수 비율은 0.9이었고 암컷 수명은 11.8일이었다. 산란과 기주체액섭취는 주로 아메리카잎굴파리 3령유층을 선호하였다.

This study investigated the oviposition characteristics of Protaetia brevitarsis seulensis after emergence as adults from the larva collected from three regions in Gangwon-do, Chungcheongnam-do, and Jeju-do. The laying egg method was identified with zone breeding, and the average and cumulative number of eggs laid were measured once a week for seven weeks. The average number of eggs laid peaked until 4 weeks, and subsequently decreased. The source areas with respect to average number and cumulative number of eggs laid were in the order of Jeju > Chungnam > Gangwon. In conclusion, this result suggests a method for continuously improving management and economic feasibility of insect farming by securing genetic diversity, and raising the most productive breeds to select individuals form regions associated with high numbers of laid eggs.
