Lee Waters said Neil McEvoy had suggested a "great party political conspiracy theory" was behind various matters the Public Accounts Committee had investigated.
Mr Waters warned against the committee becoming a "circus".
Mr McEvoy said he was "not surprised" Mr Waters "wants to brush the failures of his government under the carpet."
Speaking in a Senedd debate about the committee's work, Mr McEvoy suggested former economy minister Edwina Hart or the first minister should be called to give evidence on several issues the committee had looked at.
They included the Welsh Government's financial support for failed companies, its sale at a loss of two shops in Pontypridd and the RIFW land deals.
"We need to get serious about ending financial waste in Wales, and I think the public accounts committee is the perfect place to do that," said Mr McEvoy .
"I'd ask the chair if he would accept my call to put to the committee the suggestion of a forensic investigation into all these matters, because Labour incompetence is endangering devolution, and we have to shed light on these matters and bring transparency."
Mr Waters responded: "It's imperative it [the public accounts committee] doesn't become a circus.
"I have no problem following any evidence and in holding governments to account with rigour but that requires all members to take the committee seriously, to engage in its work, read the voluminous papers in advance, to engage with the evidence.
"Not to spend the whole committee meeting tapping away at their iPhones then lobbing in some partisan-fuelled conspiracy theory, because that I think brings the committee into disrepute."
Mr Waters said that "when there is evidence we must follow it" and "we should be ruthless in pursuing it".
Following the debate, Mr McEvoy told BBC Wales: "I'm not surprised that Lee wants to brush the failures of his government under the carpet because he's a Labour AM.
"It's becoming a consistent theme now that when I challenge Labour on the issues their AMs resort to smears and personal attacks.
"I've highlighted Â£53m that the taxpayer has lost thanks to Labour incompetence - this isn't some conspiracy theory."

The money will be used for renewable energy projects with a particular focus on wave and tidal power generation.
Known as the Bryden Centre for Advanced Marine and Bio-Energy Research, it will recruit 34 PhD students and six post-doctoral research associates.
Funding is from the Interreg programme which supports projects in NI.
Some border counties of the Republic of Ireland and western Scotland also benefit from the Interreg programme.
Aside from marine energy projects the centre will focus on the anaerobic digestion of agri-food waste.
Match-funding for the projects has been provided by the Department for the Economy in Northern Ireland and the Department of Jobs, Enterprise and Innovation in the Irish Republic.
Partner organisations include the Ulster University, the Letterkenny Institute of Technology and the University of Highlands and Islands.
Gina McIntyre, the chief executive of the Special EU Programmes Body, which manages Interreg, said the project was aimed at tackling the low level of industry-relevant research and innovation in the local renewables sector.
"The Bryden Centre project will help address this issue by creating a new centre of competence made up of dedicated PhD students creating high quality research with strong commercial potential," Ms McIntyre added.
The Interreg programme has a total value of £240m, which is due to be distributed by 2020.
