The effects of foods on the life cycle, survival rate, and reproductive ability of Ostrinia furnacalis (Guenee, 1854) were studied in laboratory. Maize HN88-Fed O. furnacalis had a complete life cycle of 32.9 ± 1.7 days, which was 38.4 ± 1.5 days shorter than those fed with maize LVN4. The average survival rates of O. furnacalis on two types of feeds were 97.5% and 94.4%, respectively. When O. furnacalis were fed with 100% honey or 50% sugar or water, the average length of female life cycle as well as their everage laid egg number were 11.1 ± 0.9 days and 535.2 ± 77.2 eggs/female; 9.9 ± 0.8 days and 371.7 ± 47.4 eggs/female; 7.3 ± 0.6 days and 216 ± 32.6 eggs/female, respectively.

1. The geographical distribution of cattle lice in Britain is recorded in detail. Bovicola bovis is the commonest and most widely distributed species in Britain.2. The incubation period for the eggs was found to be: Haematopinus eurysternus, 9–19 days (av. 12); Bovicola bovis, 7–10 days (av. 8); Linognathus vitula, 10–13 days; Solenopotes capillatus, 10–13 days. With eggs of H. eurysternus it was found that the higher the minimum air temperature the shorter was the incubation period.3. In H. eurysternus the average length of the instars was: 1st, 4 days; 2nd, 4 days; 3rd, 4 days; pre-oviposition period, 3–4 days. The average time for the complete life cycle, egg to egg, was 28 days.4. The maximum longevity of H. eurysternus on the host was: males, 10 days; females, 16 days. No males or females of H. eurysternus survived a starvation period of 72 hr. at 20° C. and R.H. 70 or 0–10° C. and R.H. 70–85; but some nymphs survived this period at 20° C. and R.H. 70, but none survived 96 hr. starvation.5. The maximum number of eggs recorded for one female was 24; and eggs were laid at the rate of 1–4 a day.6. The threshold of development of the eggs of H. eurysternus appears to be about 27·5° C.

Abstract. Arminudin AT, Suputa, Wijonarko A, Trisyono YA. 2020. Ultrastructure characters and partial mtDNA-COI haplotypes of Asian corn borer, Ostrinia furnacalis (Guenée) (Lepidoptera: Crambidae) from Indonesia. Biodiversitas 21: 2914-2922. In addition to the confirmation of the species of corn borer, we analyzed the relationship of Ostrinia furnacalis in Indonesia with that in other countries. Moths of O. furnacalis were collected from several areas in Java and Sumatra islands of Indonesia. Forewing and labial palpi scales were investigated under Scanning Electron Microscopy observation. A 658 bp of O. furnacalis partial COI gene sequences of 1480-2138 nucleotides were downloaded from GenBank and BOLD system databases. The ridge lamellae and window characters as unique ultrastructure characters of scale were further supported by the COI gene analysis. High similarity was observed between the Java and the Philippines specimens, but they were a different haplotype compared with Sumatra’s specimen. The results could provide the baseline data on the genetic variation of O. furnacalis in Indonesia.

The objective of the present study was to document the growth and survival rates of Hippocampus abdominalis, beginning from captive-born to adulthood, and finally to the complete life cycle. The most significant finding from this culture study was that, after day 193, the life cycle of first generation of captive-born H. abdominalis in AkuaTAR was successfully observed. It is claimed that this is the first successful life cycle in captivity and production of the next generation of H. abdominalis in Malaysia. Our finding was obviously better because the survival rate was significantly higher when compared to those previously reported for this seahorse species. In short, the present observational study presented a simple culture technique that can produce optimum growth and survival through to adult stage of seahorse H. abdominalis. Hence, the present finding is important for conservation of seahorse H. abdominals in the future. Keywords: Seahorse; Hippocampus abdominalis; Closure of life cycle; Conservation

Parthenium Weed

Parthenium hysterophorus Linn. is one of the most aggressive, invasive weeds threatening natural and agricultural ecosystems in the world including Nepal. Augmentative release of host-specific, leaf feeding beetle, Zygogramma bicolorata Pallister (Coleoptera: Chrysomelidae) is one of the sustainable management approaches of parthenium weed. Successful mass rearing program requires knowledge on biology of Z. bicolorata for augmentative release. Thus, life cycle and biology of Z. bicolorata were studied in lab at 26±2 °C temperature and 70±10% relative humidity at NARC, Lalitpur, Nepal during March to September, 2016. The average incubation, larval and pupal periods of the insect were 4.33, 12.20, and 11.00 days, respectively. A single female could lay 1,837 eggs in 58.80 days oviposition period with 73.01% egg hatchability. The insect completed its life cycle in 108.40 and 105.50 days with adult longevity of 91.90 and 75.00 days for females and males, respectively. The average length of egg, pupa, adult female and male was 1.19 mm, 5.90 mm, 6.58 mm and 5.32 mm and breadth 0.51 mm, 3.74 mm, 3.94 mm and 3.20 mm, respectively. The average lengths of the first, second, third and fourth instar larvae were found 1.30 mm, 3.02 mm, 4.96 mm and 8.08 mm and breadth of 0.44 mm, 1.13 mm, 2.02 mm and 3.16 mm, respectively. These findings will help in mass multiplication of Z. bicolorata for biological control of parthenium weed.

ABSTRACTSpodoptera litura is one of the important insect pest of maize besides the notoriously damaging corn borer, Ostrinia furnacalis. S. litura has been the target of various controls including the use of Bacillus thuringiensis (Bt) toxin Cry1A.105 and Cry2Ab2. This study was conducted to evaluate the acute effect of Bt toxin Cry1A.105 and Cry2Ab2 on the growth and development of S. litura from larval to adult stages. Two sublethal concentrations were used; 0.1875 and 0.0469 ppm for Cry1A.105, and 0.0008 and 0.0003 ppm for Cry2Ab2. The bioassay using diet dipping was carried out on a CRD with three experiments and five repetitions. The observation was carried out on the mortality and survival rates of S. litura. The mortality reached 28% when the larvae were treated with 0.1875 ppm and 20% with 0.0469 ppm of Cry 1A.105. The exposed larvae and pupae were smaller than control. Larval and pupal weight were 117.0 and 165.6 g with 0.1875 ppm, while control were 212.9 and 211.2 g. Cry1A.105 also longer the larval stage, larval stage with higher and lower concentration were 24.5 and 22.3 day, while control was 20.5 day. The resulted pupae from larve which exposed by Cry1A.105 were less than control; there were 40% at concentration 0.1875 ppm and control 61%. The two concentration of Cry2Ab2 produced similar mortality of 20%. Similarly, Cry2Ab2 affected pupal to adult stages development. The longevity of pupal stage with concentration 0.0003 ppm was 9.5 days, followed by 0.0008 ppm (9.1 days) and control (10.1 days). The adult emerge on the highest concentration was 47.4% while control only 34.6%. There results showed that both Cry1A.105 and Cry2Ab2 were detrimental to the survival of S. litura which is the non-target insect of transgenic Bt maize.Keywords: Cry1A.105, Cry2Ab2, maize, non-target pest, Spodoptera litura, survival INTISARISpodoptera litura merupakan salah satu hama penting yang menyerang tanaman jagung, selain Ostrinia furnacalis. Belakangan ini O. furnacalis diketahui telah menjadi target dari berbagai macam cara pengendalian termasuk penggunaan toksin Bacillus thuringiensis (Bt) Cry1A.105 dan Cry2Ab2. Penelitian ini dilakukan untuk mengetahui efek akut toksin Bt Cry1A.105 dan Cry2Ab2 terhadap pertumbuhan dan perkembangan S. litura dari larva sampai imago. Dua konsentrasi subletal yang akan digunakan adalah; 0,1875 dan 0,0469 ppm untuk Cry1A.105, dan 0,0008 dan 0,0003 ppm untuk Cry2Ab2. Pengujian dilakukan dengan menggunakan metode celup pakan dan Rancangan Acak Legkap dengan tiga perlakuan dan lima ulangan. Pengamatan dilakukan terhadap mortalitas dan kelangsungan hidup S. litura. Mortalitas mencapai 28% pada larva yang dipaparkan dengan 0,1875 ppm dan 20% dengan 0,0469 ppm Cry 1A.105. Larva dan pupa yang terkena toksin berukuran lebih kecil. Berat larva dan pupa yang terpapar toksin dengan konsentrasi 0,1875 ppm, masing – masing 117,0 dan 165,6 g, sedangkan kontrol masing – masing 212,9 dan 211,2 g. Cry1A.105 juga dapat memperpanjang stadia larva. Lama stadia larva dengan konsentrasi tertinggi dan terendah adalah 24,5 dan 22,3 hari, sedangkan kontrol 20,5 hari. Jumlah pupa yang berhasil terbentuk dari larva yang terpapar toxin Cry1A.105 lebih sedikit dibandingkan dengan kontrol; pada konsentrasi 0,1875 ppm sebesar 40%, sedangkan kontrol sebesar 61%. Kedua konsentrasi dari toksin Bt Cry2Ab2 menyebabkan mortalitas yang sama yaitu 20%. Cry2Ab2 juga berpengaruh terhadap lama stadia pupa dan tingkat keberhasilan pembentukan imago. Lama stadia pupa dengan konsentrasi 0,0003 ppm adalah 9,5 hari, diikuti dengan konsentrasi 0,0008 ppm (9,1 hari) dan kontrol (10,1 hari). Jumlah imago terbanyak terdapat pada perlakuan dengan konsentrasi 0,0008 ppm sebesar 47,4% sedangkan pada kontrol hanya 34,6%. Hal ini menunjukkan bahwa toksin Bt Cry1A. 105 dan Cry2Ab2 juga berpengaruh terhadap kelangsungan hidup S. litura yang merupakan serangga bukan sasaran dari tanaman jagung transgenik Bt.Kata kunci: Cry1A.105, Cry2Ab2, hama bukan sasaran, jagung, kelangsungan hidup, Spodoptera litura

Ostrinia furnacalis is a corn stem-borer that develops complete metamorphosis and all stages in life cycle in corn. This research was aimed to examine several biology aspects of O. furnacalis such as life cycle, egg incubaton period, egg fertility, female fecundity, longevity of imago, and copulation time on artificial diet, based on the previous study. The results of the observations showed that the life cycle of artificial-diet-given O. furnacalis was between 27-34 days range. Female fecundity was 16-452 eggs with fertility rate of 61,97% and 3-5 days renge of egg incubation period. Longevity of imago was between 6-11 days range, and the longevity was longer in female compared to the male. The imago of O. furnacalis copulate on 0-3 days after emerge from pupae and the highest number in on the day 1. Copulation time was occurred at 3-8 hour after scotophase commenced and the highest was at third hour. The artificial diet used in this research can be used for O. furnacalis mass rearing purpose and performed shorter length of egg stage until pupal stage compared to mass rearing with natural diet.

AbstractThe genealogy and diversity of the mitochondrial cytochrome oxidase subunit II (COII) gene were investigated for Ostrinia furnacalis in Japan. A preliminary examination of mitochondrial lineages in China and the Philippines was also made. Two lineages (A and B) were found in the COII gene. Lineage A was frequent throughout the Japanese main islands (Hokkaido, Honshu, Shikoku and Kyushu), while the frequency of lineage B varied among these islands. No clear patterns of geographical population structure were found. Population genetic features suggested that the O. furnacalis population harboring the lineage A mitochondria expanded in the recent past, while lineage B showed weak signals of a population expansion. It is not clear whether the two lineages of mtDNA evolved in separate or identical geographical regions. We discuss two hypotheses regarding the two lineages of mtDNA: a cryptic race/species hypothesis and a selective sweep hypothesis.

Abstract Various information technology (IT) infrastructures for biobanking, networks of biobanks and biomaterial management are described in the literature. As pre-analytical variables play a major role in the downstream interpretation of clinical as well as research results, their documentation is essential. A description for mainly automated documentation of the complete life-cycle of each biospecimen is lacking so far. Here, the example taken is from the University Medical Center Göttingen (UMG), where the workflow of liquid biomaterials is standardized between the central laboratory and the central biobank. The workflow of liquid biomaterials from sample withdrawal to long-term storage in a biobank was analyzed. Essential data such as time and temperature for processing and freezing can be automatically collected. The proposed solution involves only one major interface between the main IT systems of the laboratory and the biobank. It is key to talk to all the involved stakeholders to ensure a functional and accepted solution. Although IT components differ widely between clinics, the proposed way of documenting the complete life-cycle of each biospecimen can be transferred to other university medical centers. The complete documentation of the life-cycle of each biospecimen ensures a good interpretability of downstream routine as well as research results.
