Black soldier fly emergence (Saito)

 

Like above picture, some BSF larvae start to emergence. These days, I get some BSF adult. Actually I am not sure it can be growth well. Because I collect in winter season. I was relived I can see some BSF emergence. But, now I have problem which emergence is not same time. So, I can not keep high density BSF adult. this is main problem I have. I observe first emergence around 3 weeks before and I see BSF emergence yesterday also. This was collected same time. It seems the duration they need for emergence is not same or I miss some important information to emergence.　Anyway I need to study more about BSF.

 


写真にあるようにアメリカミズアブの蛹が羽化し始めました。最近ようやく、ミズアブの成虫が出てきました。蛹から捕まえてきて25℃で飼育して成虫になるかどうかわからず不安でしたがとりあえずは蛹から成虫までの流れが確認できたので良かったとおもいます。しかし、成虫になるタイミングにずれがあり、一度にたくさんのミズアブの密度を維持できないという問題があります。最初に観察できたミズアブの成虫は約3週間前、最近で羽化したミズアブは昨日とタイミングにかなりのばらつきがあります。同じ時に採取したものなので個体差による違いなのかそれとも自分が何か重要な情報を見落としているのか、とりあえずミズアブについて勉強しようと思います。

HAZARD VS. RISK-BASED APPROACHES TO PROTECTING HEALTH (ERNEST)

                                               HAZARD VS. RISK-BASED APPROACHES TO PROTECTING                             HEALTH AND ENVIRONMENT FROM PESTICIDES                                                                      April 2021     What’s the difference between a hazard and risk-based approach? These two approaches are often presented as opposing. However, this is a misrepresentation of risk management. ‘Hazard’ is the potential for a chemical (in this case a pesticide) to cause harm to human health or the environment; Risk , on the other hand , is the probability that the harmful outcome happens. Hazard cannot be separated from risk; it is an integral part of it. Pesticide risk management focuses on reducing the probability (and hence frequency), that people or the  environment will be exposed to pesticides. The hazard-based approach to pesticide regulation is founded on the principle that if an active substance possesses certain hazardous character

Locust as a source of food and feed (Rahima)

イメージ
I came across a pack of roasted locusts at the store the other day and decided to check their nutritional value and study a bit more about them. Locusts are a type of insect from the family Acrididae . They are known to swarm in huge numbers and can travel great distances, causing considerable damage to crops. However, in many African, Middle Eastern, and Asian countries, locusts are considered a delicacy and eaten in abundance. Locusts are an excellent source of protein and contain a variety of fatty acids and minerals. Although not considered palatable by most Americans and Europeans, locusts are an important food source in many other countries.   According to the book "Insects" by Steve Parker, species of locusts vary in protein content from about 50 percent of dry weight to almost 60 percent, making them denser in protein than cows . Researchers have also noted that the cholesterol content in locusts is high, about 286 milligrams per 100 grams, which is higher than th

Full vaccination（Sagae）

イメージ
We some of the lab members had second vaccination at university. It was so hard situation for me because of side effects. I had heard some news that the side effects of the second vaccine are more serious. It was TRUE. The night after the vaccine, started to increase my body temperature. At midnight temperature already reached 38.5 ℃. And also my bone has pain and "Moderna arm". I could only lay on the bed the whole day by agony. My fever continues till next midnight. I thought my fever had gone down, but then I started to have terrible headaches. Again I spent the time on the bed the whole day. Finally, I recovered fully after 60 hours of vaccination. It was the worst experience in 2021 at least. I wish our painfulness contributes to making the situation better. 大学で二回目のワクチン接種を受けました。結論から言うと、副反応が本当きつかったです。二回目は一回目より副反応がきついと聞いていましたが、その通りです。接種日の夜から熱が上がり始めて、夜中には38.5℃に達しました。きつすぎてベッドに横になる事しかできません。全身の関節は痛むし、モデルナアームも発症しています。次の夜中は明朝まで高熱は続きました。熱が下がったと思ったら次はひどい頭痛です。またベットから動けず一日を過ごします。最終的
