| malfunction | knockdown of LdUAP1 reduces chitin contents in whole larvae and integument samples, thins tracheal taenidia, impairs larval-larval molt, larval-pupal ecdysis and adult emergence. Combined knockdown of LdUAP1 and LdUAP2 causes an additive negative effect. Phenotypes, overview | Leptinotarsa decemlineata |
| malfunction | silencing of LdUAP2 significantly reduces foliage consumption, decreases chitin content in midgut samples, damages PM, and retards larval growth. The resulting larvae have lighter fresh weights, smaller body sizes and depleted fat body. As a result, the development is arrested. Combined knockdown of LdUAP1 and LdUAP2 causes an additive negative effect. Phenotypes, overview | Leptinotarsa decemlineata |
| physiological function | knockdown of UAP1 reduces chitin contents in whole larvae and integument samples, thinned tracheal taenidia, impairs larval-larval molt, larval-pupal ecdysis and adult emergence.
