This paper is a review of some experiments using black soldier fly (BSF) and its by-product to explore their nutritional value, production potential in Indonesia and its application in the ration of ruminants. Evaluation on the effect of milk replacer, creep feed containing BSF, BSF frass and the possibility to use lactic acid bacteria from BSF as probiotics are presented. Utilization of BSF larvae in milk replacer as skim and cream milk substitute showed that there were similarity on physiological, hematological status and performance of goat kids compared to those offered goat milk or commercial milk replacer. In addition, BSF larvae can be used to substitute soybean meal in the creep feed for post weaning goat kids without any differences in weight gain and blood profiles. However, utilization of BSF frass in the fattening goat ration resulted lower digestibility of dry matter and organic matter due to the chitin content in the frass. Black soldier fly larvae grown on chicken manure harbour lactic acid bacteria (LAB) which have potential as probiotics for ruminants. In general, BSF larvae has potential as ingredient for milk replacer, creep feed, fattening ration, and source of LAB for probiotics.

1) 버들재주나방은 년 3-4회 발생하는데 제 1회발생은 5월 중순내지 6월 초순경이며 유충으로 월동한다. 2) 성충의 평균수명은 숫놈이 5,8일이고 암놈이 5.9일이다. 3) 난기간은 약 4일이고 유충기간은 약 17.2일이며 용 기간은 5-8일이다. 4) 유충의 두폭은 1령기에 0.37mm 이고 최종령기에 2.45mm 이다. 5)실내 조건하에서 유충의 섭식량은 암놈의 경우 $95cm^2$이었고 숫놈의 경우 $60cm^2$이었다. 6) 유충의 배분수는 실내에서 682개이고 야외에서 663개이었다. 7) 배분의 크기는 유충의 영기에 따라 길이가 0.11mm에서 2.46mn, 직경이 0.05mm에서 2,92mm로 변하였다. 8) 암놈 한 마리당 포난수는 400개이며 산란율은 평균 $80\%$이었다.

본 연구(硏究)는 잣나무넓적잎벌(Acantholyda posticalis posticalis)의 가해량(加害量)과 섭식량(攝食量) 및 탈분량(脫糞量)을 조사(調査)하여 피해수준(被害水準)과 개체군밀도(個體群密度)를 파악(把握)하고 이에 의해 본(本) 해충(害蟲)의 관리(管理) 및 방제전략수립(防除戰略樹立)을 위한 기초자료(基礎資料)로 제공(提供)하기 위하여 수행(遂行)되었으며 얻어진 결과(結果)는 다음과 같다. 잣나무넓적잎벌유충당(幼蟲當)의 잣나무잎 평균가해량(平均加害量)은 암수 각각(各各) 약(約) 11,774mm와 7,394mm였고 평균가해량(平均加害量) 약(約) 9,584mm였다. 총가해량(總加害量) 중 실제(實際)로 해충(害蟲)이 섭식(攝食)한 엽량(葉量)은 7,797mm로 총가해량(總加害量)의 81.4%였고 잔량(殘量)은 18.6%였다. 총가해엽량(總加害葉量)의 83%는 4령기(齡期)와 5령기(齡期)에 집중(集中)되었으며 3령기(齡期) 이하(以下)의 가해량(加害量)은 17%에 불과(不過)하였다. 일일중(一日中)의 가해량(加害量)과 섭식량(攝食量)의 비율(比率)은 령기별(齡期別)로 뚜렷하여 가해량(加害量)은 노령기(老齡期) 일수록, 그리고 섭식량(攝食量)은 우령기(幼齡期) 일수록 높게 나타났다. 수상유충기(樹上幼蟲期)의 유충당(幼蟲當) 평균탈분수(平均脫糞數)는 약(約) 1,160립(粒)으로 암수간(間)에는 차이(差異)가 없었으나 령기별(齡期別)로는 현저한 차이(差異)가 있었다.

Cockroaches can cause allergic sensitization in humans via contact with their feces or frass. Antibiotics can affect concentration of major allergen and total bacteria production in German cockroaches (Blattella germanica). This study examined the ability of antibiotic-treated German cockroaches to induce allergic airway inflammation and the effect of antibiotics on their lipopolysaccharide and Bla g1, 2, and 5 expression levels. Specifically, we measured the ability of German cockroach extract (with or without prior antibiotic exposure) to induce allergic inflammation in human bronchial epithelial cells and a mouse model of asthma. Bacterial 16S rRNA and lipopolysaccharide levels were lower in ampicillin-treated cockroaches than in the control group. The Bla g1, Bla g2, and Bla g5 expression in ampicillin-treated cockroaches decreased at both the protein and RNA levels. In human bronchial epithelial cell lines BEAS-2B exposed to the ampicillin-treated extract, expression levels of interleukin-6 and interleukin-8 were lower than that in the control group. The total cell count and eosinophil count in bronchoalveolar lavage fluid was also lower in mice exposed to the ampicillin-treated extract than in those exposed to normal cockroach extract. Mouse lung histopathology showed reduced immune cell infiltration and mucus production in the ampicillin group. Our results showed that ampicillin treatment reduced the symbiont bacterial population and major allergen levels in German cockroaches, leading to reduced airway inflammation in mice. These results can facilitate the preparation of protein extracts for immunotherapy or diagnostics applications.
