Spiders are important predatory enemies that control the pests of various insects in the rice ecosystem. m– Aminophenylacetylene (m-a) has been demonstrated to induce maternal care behaviors Pardosa pseudoannulataprotects young spiders and promotes population growth. The role here m-A of other breeding stages was assessed by injection m– For virgins and post-nutritional female spiders. When injected into a virgin woman, m-A can extend the first pull-re-carry stage of a woman after mating and breeding offspring. In post-reproductive females, m– In particular, in the second and third stages, injections shortened the egg SAC carry stage. Transcriptome analysis showed differentially expressed genes between control females m– Injected females were concentrated in the arachidonic acid (AA) metabolic pathway. Real-time quantitative PCR (QPCR) confirmed upregulation of Cyclooxygenase-II (cox-ii),, Prostaglandin E Synthase 2 (PGES2), and Prostaglandin E Synthase 3 (PGES3) Genes involved in PGE2 (Prostaglandin e2) Synthesis. In the reverse verification experiment, continuous injection of mFollowing -A, the Cox inhibitor aspirin was recovered to normal levels at a tempered egg sac-injection stage. The survey results showed that m– PGS synthesis is enhanced and the stage of carrying egg SAC is reduced. If a female spider encounters an enemy, the egg breeding stage can be fatal, so the stage shortening is m-A reduces potential threats. These findings are important for developing environmentally friendly control strategies.
