The price of defence: Maternal effects in an aposematic ladybird [PDF]
, 2016 Offspring phenotype can be adaptively altered via maternal non-genetic inheritance. Such ‘maternal effects’ enable females to adjust their per offspring investment in response to variation in the offspring environment, and thus maximise their ...

Understanding the impact of Bacillus thuringiensis proteins on non-target organisms [PDF]
, 2019 Bacillus thuringiensis (Bt) is a spore-forming, gram-positive, aerobic, rod-shaped bacterium. During sporulation, Bt produces proteinaceous crystals called Cry proteins that are lethal to many insects’ species, so are commonly used as biological ...

Flower strips increase natural pest control of peanut aphids, thereby enhancing crop yield [PDF]
Flower strips can enhance biodiversity and predation on pests by attracting predators. To improve their effectiveness in natural pest control and crop production, we need to understand the mechanisms that determine their success or failure.

Kyushu Plant Protection Research, 1999 耐久卵,ショ糖および酵母Y2Aを等量混合した基本飼料と,これにトリレバー粉末あるいは食用花粉粉末を添加した3種類の人工飼料を用いて,ナミテントウ幼虫およびヒメカメノコテントウ幼虫の飼育を試みた。ナミテントウ幼虫は,いずれの飼料でも成虫が得られたが,羽化率や飼料調整の点から基本飼料にトリレバー粉末を添加した飼料が最適と考えられた。また,ヒメカメノコテントウ幼虫も本試験で用いた人工飼料を与えることで成虫が得られ,雄蜂児粉末以外の人工飼料でも飼育が可能であった。しかし,蛹化率,羽化率が低く,また,羽化成虫の小型化が見られたことから,さらに改良が必要と考えられた。安価な酵母Y2Aを用いた人工飼料は,ナミテントウ幼虫およびヒメカメノコテントウ幼虫の飼育が可能であり ...
