Let E■R be an interval. By studying an admissible family of branching mechanisms{ψt,t ∈E} introduced in Li [Ann. Probab., 42, 41-79(2014)], we construct a decreasing Levy-CRT-valued process {Tt, t ∈ E} by pruning Lévy trees accordingly such that for each t ∈E, Tt is a ψt-Lévy tree. We also obtain an analogous process {Tt*,t ∈E} by pruning a critical Levy tree conditioned to be infinite. Under a regular condition on the admissible family of branching mechanisms, we show that the law of {Tt,t ∈E} at the ascension time A := inf{t ∈E;Tt is finite} can be represented by{Tt*,t∈E}.The results generalize those studied in Abraham and Delmas [Ann. Probab., 40, 1167-1211(2012)].

Ostrinia fumacalis (Lepidoptera: Pyralidae) is one of the most destructive agricultural pests in Asia. Traditional pest-management methods include sex pheromone capture, transgenic crops that produce Bacillus thuringiensis toxin, and pesticides. Although these strategies control pest populations effectively, they also cause negative side effects, including dramatically increased pesticide resistance, severe pollution, and hazards for human health. Recently developed genome editing tools provide new prospects for pest management and have been successfully used in several species. However, few examples have been reported in the agricultural pest O. fumacalis due to a lack in genomic information. In this report, we identified only one transcript of O. fumacalis Argonaute 1 (OfAgo 1) gene from the genome and cloned the open reading frame. OfAgol presented the maximum expression at the embryo stage or in the fat body during the larval stages. To understand its function, an OfAgol mutant was constructed using the Clustered Regularly Interspaced Short Palindromic Repeat/RNA-guided Cas9 nuclease (CRISPR/Cas9). Mutagenesis of OfAgol disrupted cuticle pigmentation by dowregulating micro RNAs and pigmentation-related genes. This is the first report for the cloning and functional analysis of OfAgol, revealing a role of OfAgol in cuticle pigmentation. The current report also established a CRISPR/Cas9 system in O. fumacalisy providing a new insight for pest management.
